SEO – What Is It? Search Engine Optimization in 2026

SEO, also known as Search Engine Optimization—or, in Danish, “søgemaskineoptimering”—is about improving your rankings in organic search results.

But how do you go about doing that? In this comprehensive guide to search engine optimization (SEO) in 2025, you’ll (hopefully) find answers to all your questions. All the tips in this guide are based on my personal experience with SEO—a field I’ve been working in one way or another since 2015.

Disclaimer: There's no one-size-fits-all solution for SEO!

The points in this article are based on my personal experience with search engine optimization. They should therefore not be viewed as a definitive guide to your SEO strategy—rather, they are empirically based examples of how various measures can influence Google’s algorithm.

I have a total of 8 years of experience in SEO—first 3 years as a freelance copywriter, and the last 5 years as an in-house SEO specialist at Amplify. I have a background in communication and rhetoric, which is why I also have a strong interest in content optimization and semantic SEO. In addition, over the past few years, I have developed a growing interest and knack for analysis, strategy, and technical SEO.

So, for many years, I have tried out and tested the tips you can read about in this article—and I can conclude that they work! 

I hope you, too, will have the courage to dive into search engine optimization and gain your own experience—and that this article will inspire you to get started.

Does it still seem too complicated? If so, you’re always welcome to reach out to me or one of my colleagues—as an SEO agency, we at Amplify always keep an eye on industry best practices, and of course, we have the necessary in-depth overview.

What is SEO—and what is its purpose?

SEO, search engine optimization, Search Engine Optimization, and even SEO optimization.

A beloved child has many names, and the same is true when it comes to SEO.
SEO is an abbreviation for Search Engine Optimization.

Despite the confusion over terminology, the goal remains the same: Search engine optimization (SEO) is, in short, about optimizing your website—both in terms of content and technical aspects—so that it ranks for valuable keywords and appears at the top of Google’s search results.

And there’s a good reason to be visible on Google Search in particular. This search engine is one of the best-known and most widely used in the world—in 2023, Google had a globalmarket share of 83.49% for desktop searches.

In Denmark, Google has amarket share of about 94%, giving it a virtual monopoly. It is no coincidence that the verb “to google” has become synonymous with searching the web.

And this is where SEO comes into play. Search engine optimization
gives you the best chance of appearing in the search results on the world’s largest search engine when potential customers search for your services or products.

Get Noticed on Google with Search Engine Optimization

So why should you focus on search engine optimization? 

Quite simply because it could be your shortcut to success on Google—and thus success for your business. It’s one thing to have a website. It’s quite another to get it seen by your target audience.

And this is where SEO comes into play. Sure, you can reach the top of Google through Google’s paid search results,Google Ads. But since the vast majority of users searching for information click on the so-called organic search results rather than ads, it’s absolutely essential to be visible where users are clicking.

Without a targeted SEO effort, however, your website will most likely languish in the darkest corners of Google—far from the attention of your potential customers. That’s why SEO is an indispensable part of your marketing strategy if you want to drive traffic to your website.

With a targeted and structured SEO strategy, you can achieve the following benefits:

Search engine optimization can ultimately help generate more revenue for your business. In other words, it can be a valuable investment for your company.

SEO, SEA, and SEM—what's the difference?

The acronyms SEO, SEA, and SEM can certainly cause confusion—even for more experienced marketers.

SEM stands for Search Engine Marketing and, simply put, refers to all the marketing activities you can carry out on search engines—both paid and organic.

As mentioned, the term “organic SEO” stands for Search Engine Optimization, while “SEA” stands for Search Engine Advertising. With SEA, we’re talking about advertising on search engines—for example, text ads in search results, Google Shopping, and Performance Max. This brings us to the paid aspect of SEM.

Google Ads is often considered synonymous with SEA because Google holds such a large share of the market—much in the same way that search engine optimization is often implicitly used as a synonym for Google optimization.

But you can certainly do both SEO and SEA on other search engines—for example, Bing, YouTube, Pinterest, etc.

So, to summarize, SEM is an umbrella term, and SEO and SEA fall under this umbrella. To make things even more confusing, in recent years it has become more common to use SEM as a synonym for SEA—and thus as the opposite of SEO. Similarly, the term SEA isn’t used as often anymore.

But let me put it this way: All SEO is SEM, but not all SEM is SEO. Just as all SEA is SEM, but not all SEM is SEA. And that’s enough rambling about marketing acronyms for now.

SEO in 2025 – Nice-to-Knows and Must-Knows

You have to stay on top of things to succeed with SEO. Algorithms and ranking factors—and thus best practices—are constantly changing. That’s why, as an SEO specialist, you need to stay constantly up to date. Search engine optimization is never static.

The advice provided in this article is still relevant—but SEO in 2025 will require an even broader focus if you want to rank highly in search results.

So what do you need to know to succeed with SEO in 2025? I’ll share a few suggestions below. If you’d rather get started with general tips on search engine optimization, click through to the section titled “How to Do SEO.” 

In my look into the crystal ball for 2025, I’ll discuss:

Programmatic SEO – Automation of SEO Processes

Programmatic SEO is an AI-based method that uses automation to develop, write, and create many landing pages at once. Using AI, templates, and data, you can produce and optimize hundreds—or even thousands—of landing pages at once, thereby targeting a wide range of specific search queries simultaneously.

This makes it possible to deliver relevant content to users while also achieving greater visibility on search engines like Google, without spending the countless hours it would otherwise have taken to brainstorm, write, and create the many landing pages.

This method is particularly effective for companies that want to cover a wide range of keywords with minimal effort—without compromising the quality of their content.

I highly recommend that you visit our page on this topic if you’d like to learn more about programmatic SEO—and, in particular, how it can benefit your SEO strategy.

AI Overviews – Google Search Generative Experience

In May 2023, Google announced that it would be developing its search function so that, in the future, you’ll also receive an AI-generated response to your search query. These AI-generated answers will be presented in a so-called “AI snapshot” above the traditional search results, designed to provide users with a more personalized answer that matches their search intent.

And in May 2024, it happened: Google officially began rolling out SGE in the U.S. This means that Google now—under the name “AI Overviews”—offers AI-organized search results, providing a whole new way to navigate search results.

The new AI integration will be a great help when you want to perform more complex searches. Instead of having to break down your searches and piece everything together yourself, SGE will allow you to ask more complex questions or in-depth queries—and actually receive in-depth answers that match your search intent.

An important point for website owners and those interested in SEO is that SGE highlights the sources used to generate the AI response. This means that your website could potentially be featured both as a source in the AI response and as a standalone search result.

Although we do not know for certain the exact launch date for SGE in Denmark, it will most likely be available to Danish users in 2024—and there is no doubt that the future of SEO will likely focus even more on creating high-value content for users. As a result, Google’s E-E-A-T guidelines will also become even more prominent, as Google will likely prioritize trustworthy and high-quality content to an even greater extent with the rise of AI.

I've written a short post about AI Overviews that you might find helpful to read if you want to learn more about how AI-generated search results work—and, in particular, how they can affect SEO.

A demonstration of the Google Search Generative Experience

E + EAT = EEAT – the extra E

The so-called E-E-A-T guidelines have been a ranking factor in Google’s search engine since 2018, and when Google added an extra “E” to its E-A-T guidelines in late 2022—which are now called E-E-A-T (or “Double E-A-T”), the principles became even more relevant.

E-E-A-T is an acronym for “experience,” “expertise,” “authoritativeness,” and “trustworthiness,” and is essentially a way of signaling to Google—and, not least, to Google users! – indicating that a website demonstrates precisely those four qualities.

In other words, the content on your website must reflect your experience, expertise, authority, and credibility within your field or industry if you want to rank highly in Google’s search results.

On amplify.dk, for example, all of our content is written by experienced marketing specialists who, thanks to their knowledge of digital marketing, have the expertise and practical experience to explain topics in this field. Our authority stems, among other things, from our reputation—for example, through customer testimonials on our references page and reviews on Trustpilot and Google.

Furthermore, authority comes from links and references from other websites that are authoritative within our industry. Finally, we demonstrate credibility by having a website that is safe for our users to navigate—for example, through our SSL certificate.

SEMrush has written a very informative article about E-E-A-T if you'd like to read more examples of the four characteristics of E-E-A-T.

E-E-A-T is particularly important for so-called YMYL (Your Money or Your Life) websites—that is, websites that deal with either health or financial stability. A dentist, a private hospital, or a mutual fund are examples of businesses with YMYL websites.

As mentioned, the E-E-A-T guidelines will become even more relevant as more AI-generated content emerges. Although AI can analyze large datasets, robots lack human experience, which can limit their expertise, authority, and, at times, credibility. Therefore, the combination of AI-generated content that has been reviewed (and thus not necessarily created by humans) is usually the best solution for producing the most valuable content.

E-E-A-T is inextricably linked to the Google Helpful Content Update (I’ll discuss this in the next section), as Google now expects websites not only to answer users’ questions but also to actually enrich their knowledge and experience.

That is why the E-E-A-T principles must be crystal clear to everyone working in digital marketing—and, of course, this will still be true in 2024.

E-E-A-T – one of the most important concepts in SEO
Knowledge of the E-E-A-T principles is a must for SEO professionals in 2024

Google Helpful Content Update

Because the E-E-A-T principles are such important components of Google’s guidelines and will likely become even more prominent in 2024, it’s worth investing time in building so-called“topic clusters”in the new year.

Topic clusters are an SEO approach that focuses more on topics than on keywords. It’s a concept based on organizing your website’s content into topic clusters to help search engines navigate it more easily and increase your visibility.

At the heart of a topic cluster is a “pillar page” that covers a broad topic and is supported by several “supporting pages” that address related subtopics. This structure provides comprehensive coverage of a topic, enhances user experience, and boosts your brand’s credibility.

To build an effective topic cluster, start by selecting an overarching topic for your pillar page and identifying related subtopics for your supporting pages. Remember to include internal links between the pages to strengthen the cohesion. The ideal size of a topic cluster varies, but the most important thing is to maintain focus and depth on the topic.

Topic clusters offer several benefits: they increase the likelihood of ranking for more keywords, improve user experience, and build authority. By grouping content around topics rather than keywords, you create a more cohesive and user-friendly structure.

In particular, topic clusters can be part of your AEO strategy (read more about AEO further down).

Topic clusters ​

Google’s“Helpful Content Update”is a crucial update for anyone who uses SEO as a targeted marketing strategy. The update was rolled out in August and September 2023, so there’s no doubt that it will be a game-changer for SEO in 2024.

With Google’s “Helpful Content Update,” content created for users rather than for search engines will be prioritized even more. The goal is to ensure that users receive relevant and trustworthy information, and Google will therefore reward pages that demonstrate genuine experience and expertise, while demoting those that lack substance.

The update particularly affects websites with over-optimized “SEO content” and a lack of in-depth, original content. To avoid a drop in search rankings, websites must demonstrate genuine expertise and offer unique value.

Google prioritizes quality over quantity, so this update may particularly affect sites in the shopping, online education, tech, and entertainment sectors that have previously focused more on search engines than on users.

Since this update also functions as a “sitewide algorithm,” it means that poor content on individual pages can affect the entire website. In other words, one weak link can ruin the whole chain. To avoid this, you’ll need to ensure consistently high quality across all your content in 2024, so that individual weak links don’t affect your entire domain.

Topic clusters focus on topics and semantics rather than individual keywords and terms

AEO – Answer Engine Optimization

Just as in 2023, there’s no doubt that AI will take a quantum leap in 2024 and continue to revolutionize the world of SEO time and again. That’s why it’s crucial to stay one step ahead in order to keep up with the explosive pace of the AI wave.

A term that will become important in 2024 is AEO, which stands for Answer Engine Optimization. AEO should be viewed as a subcategory of SEO and involves optimizing content for AI systems, including Google SGE, ChatGPT, Microsoft’s Bing chatbot, Copy.ai, and similar language models.

The challenge, therefore, is to create content that is both useful to the user and the search engine, and that can be easily incorporated into responses from SGE and other forms of artificial intelligence. This can be a difficult balance to strike, but it is nonetheless essential for achieving high SEO rankings in 2024.

My colleague Jens has written a post about AEO if you'd like to learn more about the discipline.

AI-generated content

We also can’t ignore the fact that AI is—and will continue to be—a central part of copywriting and SEO in general. The future of copywriting will likely be more of a collaboration between humans and machines. AI robots like ChatGPT will act as a kind of digital assistant, helping copywriters with everything from generating ideas to refining structure and language.

If you work with SEO content, AI is therefore a very useful tool—if used correctly. But it’s also important to emphasize that it is just a tool and not a substitute for a human.

I highly recommend having a human review your robot-generated content if you want to ensure that it is both factually accurate and complies with Google's E-A-A-T guidelines.

However, ChatGPT is incredibly good at writing user-friendly, useful content—see, for example, the screenshot below, where I asked the bot to write a product description about green tea for a fictional online store.

I then ran the text through the Helpful Content Checker GPT to ensure that it meets Google’s guidelines for helpful content. 

An example of AI-generated content
An example of SEO-optimized text generation using ChatGPT

Examples of AI prompts

The output of ChatGPT and similar language models depends on the input—the so-called prompts. The better you prompt the model, the higher the quality of the output you’ll get.

For example, ChatGPT can help you develop topic clusters—in this case, I highly recommend using the paid version of the language model. That’s because it can also generate tables.

Try this prompt, for example:

Give me 30 semantically relevant but unique topics under the main category [topic], and for each one, give me 10 different variations of the topic, each of which addresses a different search intent. Present this in a table format with the following columns: Column 1: The unique, semantically related topic; Column 2: The different variations of that topic; Column 3: A comprehensive, engaging, and thought-provoking title.

Next, select and customize the title you want, and you can now prompt it to execute your topic cluster:

Now create an outline for an article: “[title].” Write it as a professional [field/subject] expert, and write it for a [target audience] between [age-age] years old.

This way, the bot can help you not only with content ideas but also with the actual production of the content—even based on E.E.A.T. and Google’s guidelines for useful content (see the next section).

You can also use AI to optimize existing content—for example, this SEO guide, a blog post, or a landing page on your own website.

Here, you can use the following prompt:

Analyze this article using Google's "helpful content" standards regarding expertise, accuracy, transparency, comprehensibility, and reader value.

Highlight areas that comply with or do not comply with the guidelines.

Please provide specific, constructive suggestions for improving the depth, quality of the quotes, clarity, and value to readers.

Use the analysis to improve the article's shortcomings.

That way, you'll get very specific feedback to help you improve your content.

Useful content tailored to users rather than search rankings

Back in the wild 2010s, SEO involved spamming your website with landing pages targeted at various keyword combinations—landing pages that were, in turn, crammed full of the keyword you wanted to rank for.

Thankfully, that method was blacklisted by Google long ago. Google’s mission, in its own words, is to “provide the most relevant and reliable information available” for a given search, and a landing page that exists solely to rank for a specific keyword is hardly intended to provide relevant and reliable information.

That is why Google is constantly working to optimize its search engine’s content requirements—most recently with its “Helpful Content” update from August 2022. As the name suggests, the “Helpful Content” update aims to ensure that users are satisfied with the content they see in search results. In other words, the content must be useful.

So what does Google consider to be useful content? Well, useful content is:

For SEO specialists, the “Helpful Content” update means they need to (even more so) consider how they approach keyword analysis and strategy—but also how they produce content.

There’s no point in trying to rank for as many keywords as possible if the search results aren’t relevant to the user. Likewise, it’s not about flooding the web with content, but about selecting relevant content—and, most importantly, tailoring it to the specific search intent.

That’s why it’s a good idea to take a look at your competitors when developing your content strategy—what makes them rank highly? For example, you can look for:

With useful, user-focused content, you're well on your way to ranking highly in 2023.
With useful, user-focused content, you're well on your way to ranking high in 2024.

So how do you get featured snippets?

One way to do this is by focusing on your target audience and their search intent. Focus on creating great content—write for users, not for bots.

You can also take a more data-driven approach to featured snippets. In SEO tools like Ahrefs, for example, you can see which of your keywords typically trigger featured snippets.

Click on the “Organic keywords” report, sort by “SERP features” → “Featured snippets.” Click ‘Apply’ → ‘Show results’. You’ll then see a list of all the keywords on your website that have featured snippets. Is your website not ranked No. 1 under ‘Position’? Then it’s time to start optimizing your content and aim for that featured snippet.

Featured snippets will only become more prominent in 2023
Featured snippets will only become more prominent in 2024

Lower crawl frequency – fewer updates in the SERP

Real-time search engine data is gradually being taken so much for granted that very few people probably give much thought to the machinery behind the seemingly endless stream of information. But it takes considerable resources to keep a search engine as large as Google Search up to date. 

Because even though we think of Google’s search engine as “something in the cloud,” the “cloud” is actually a physical entity, consisting of countless servers spread across data centers all over the world—data centers that, in turn, must communicate with one another across countries and continents. And that kind of thing consumes a lot of power—a whole lot of it!

That kind of resource consumption doesn't sit well with Google's goal of becomingcarbon-neutral by 2030. That's why Google is continuously implementing measures to reduce its annual carbon emissions.

One of them is reportedly to limit the number of crawler requests (crawlers are essentially bots that comb the web for URLs in order to record and index them). 

Fewer crawl requests naturally also mean fewer updates to search results, since updates to search results are directly linked to crawler behavior —if your website hasn’t been visited by a crawler since your last update, you won’t see any changes until you’re visited again by Googlebot, as Google’s crawlers are called. This is why optimizing your internal link structure is the be-all and end-all of technical SEO, because Googlebot navigates the web by following links on the pages it crawls. 

In short, this means that in the long run, it will pay off to optimize landing pages according to best practices from the very beginning, rather than doing so on an ongoing basis. So if you have your keyword and content strategy in place, it’s a good idea to implement changes right away rather than updating them gradually, since bot visits will also become less frequent.

This will increase the likelihood that your changes will be indexed by Googlebot more quickly—and thus appear in the SERP.

AI—A Game-Changer for SEO in 2024

The ChatGPT language model shook the tech world to its core when it was launched in late November 2022, and this seemingly all-knowing AI has only gotten better over the past year. And a little over a year later, in early December 2023, Google unveiled its response to ChatGPT: Google Gemini. AI is here to stay—and has also become an integral part of SEO. And it will continue to be so in 2024.

Now that Google has not only accepted AI-generated content but is also launching its own AI, we must assume that AI—and AEO in particular—will become an integral part of search engine optimization.

But why? To answer this question, I asked ChatGPT to explain its own potential impact on SEO. The text below is therefore almost 100% AI-generated—I’ve only made minor corrections myself.

Automating SEO Processes with AI

Although, as an AI model, I do not actively participate in SEO (Search Engine Optimization) in the same way as a human SEO specialist, I can still play a useful role in the SEO process. Here are some ways you, as an SEO specialist, can benefit from my knowledge to streamline your work:

Search Engine Optimization: I can help you identify relevant keywords and key phrases that are important to your target audience. You can ask me questions such as “Which keywords are popular in my niche?” or “How can I optimize my content to rank higher for specific keywords?”.

Content Planning: You can use me to generate ideas for content. For example, you can ask me, “What topics are trending in my industry?” or “Can you help me brainstorm ideas for blog posts?”

Technical SEO: I can provide advice on technical SEO by answering questions about optimizing website speed, structured data, meta tags, and other technical aspects of SEO.

Competitive Analysis: I can help you analyze your competitors' SEO strategies by identifying their most popular keywords, backlinks, and content, which you can use as a reference.

SEO-friendly content: I can help you optimize your content by creating meta descriptions, titles, and headings that are optimized for search engines.

Here is an example:

Question: “What are the most popular search terms in the fitness industry right now?”

Answer: “The most popular search terms in the fitness industry include ‘weight training,’ ‘healthy eating,’ ‘fitness equipment,’ and ‘workout plans.’ It might be a good idea to create content on these topics to appeal to your target audience.”

Keep in mind that even though I can provide information and assistance with analysis, human expertise is still necessary for making decisions, carrying out implementation, and understanding the context required to run a successful SEO campaign. 

However, the synergy between AI and human judgment can be a powerful combination for streamlining the SEO process and achieving better results.

Source: ChatGPT

In addition, the launch of GPTs—customized versions of ChatGPT—in November 20223 further expanded ChatGPT’s toolkit. 

For example, in the GPT “Helpful Content Checker,” you can check whether your content meets Google’s requirements for helpful content, just as you can use Seer’s “Screaming Frog & Technical SEO Companion” to gain expert knowledge about the website crawler Screaming Frog —and even upload your crawls directly in the chat.

Not least, you can also create your own GPTs that are tailored to very specific needs—for example, writing content for organizations in their own unique tone of voice. 

In other words, the language model can help you with everything from strategy and analysis to content optimization and technical SEO.

How do you do SEO?

Search engine optimization is about optimizing a number of factors that, from Google’s perspective, equate to quality for users—and that can therefore boost a website’s ranking in search results.

In fact, Google takes hundreds of factors into account. These factors collectively determine a website’s ranking for specific keywords in search results. You can think of it as one big calculation, where every single factor influences how visible your website will be. That’s why there’s no set formula for reaching the top of Google—just as results don’t happen overnight.

Overall, however, there are three key elements that can really help you get started: content, technique, and authority.

Semantic SEO – Quality Content Over SEO-Optimized Text

Back in the day, SEO was basically about stuffing your landing pages with the keywords you wanted to rank for. I myself have a background as an external freelance copywriter at a marketing agency, where my job was to write meaningless SEO copy for clients’ websites, and where there were strict guidelines on how many times a keyword had to appear in each piece of text.

Fortunately, that’s no longer the case. Today, the search engine prioritizes, first and foremost, content that provides value to users, and over the past few years, Google has released several algorithm updates designed to ensure this—most recently in August 2022, when they rolled out their “Helpful Content Update,” which was last updated in September 2023.

The quality requirements for content mean that semantic SEO is an important third pillar of SEO. Search engines place a high priority on quality content that meets users’ expectations. Conversely, landing pages with thin, duplicated, or worthless content very rarely achieve good rankings.

For the same reason, writing good, user-friendly content for your website is absolutely essential if you want to rank at the top of Google. But that’s easier said than done. It requires a balance of rhetorical tools, an understanding of users’ search intent, and the ability to use the right keywords in the right context. You’re therefore sorely mistaken if you think it’s just a matter of cramming the most important keywords into a generic text a certain number of times.

As Google’s algorithms have evolved, the search engine has become incredibly good at understanding users’ search intent —and displaying search results based on that intent. So if you prioritize unique content designed for people rather than robots, you’re well on your way to the top of Google’s coveted rankings.

Technical SEO – Make Your Content Accessible

The content on your website is important. But if the technical aspects aren’t up to par, Google won’t be able to read the page, and the page won’t be user-friendly for your potential customers. That’s why optimizing the technical factors— technical SEO—is also a vital part of search engine optimization for a website.

Technical SEO is the slightly more complex aspect of search engine optimization. It requires a solid understanding of everything that goes on behind the scenes on your website.
In practice, technical SEO involves, among other things, analyzing:

Technical SEO also involves analyzing and redirecting broken links, creating search engine-friendly URL names, optimizing ALT and H tags, page titles, and meta descriptions, as well as setting up structured data to help Google better understand the content on the website.

And that’s just a small sample of the many tasks involved in technical SEO. Long story short, the purpose of technical SEO is to ensure that a website performs optimally from a technical standpoint. This is partly to provide users with the best experience, but also to make the site more readable for Google—and thereby increase the chances of ranking at the top of Google.

Link Building – Build Trust in Your Website

SEO isn't just about what happens on the website itself. Your website also needs to establish authority—and it does so through link building.

Link building is essentially about getting other websites to link to your website—what are known as backlinks. Roughly speaking: The more websites that link to yours, the greater the authority your website gains. However, the quality of backlinks matters more than the quantity. Having 100 spam links from casino sites, Indian link directories, and Russian porn sites is not a sign of authority. On the contrary, it’s a spam signal, and it can have a very negative impact on your organic visibility in search engines.

Conversely, having many links from a wide range of industry-relevant domains with high domain authority is a sign of authority—for example, if a dentist’s website has many links from health blogs, industry associations, etc.

The graph below is a cautionary example of the consequences of spam links. It shows the average Google ranking for a major keyword, and as you can see, it drops dramatically and even falls completely out of the index on certain days.

The website’s webmaster had the best of intentions and therefore diligently set about redirecting countless subpages from other domains he managed—domains that, it should be noted, were in no way relevant to the industry and, moreover, had low domain authority. Google therefore interpreted this as an attempt to manipulate rankings through spam links, and several months of SEO efforts were undermined in just a few days.

An example of poor link building

Here's the opposite example: A steadily growing backlink profile with links from relevant and authoritative domains has earned a subpage good Google rankings for a major keyword.

An example of good link building

An update to Google's algorithms has the industry holding its breath

It is essential to have knowledge and insight into Google’s algorithms when working with search engine optimization. After all, it is these algorithms that help determine where your website appears in search results.

That’s why an algorithm update will always have SEO specialists holding their breath—because if an update causes the whole house of cards to come crashing down, years of strategic work could go to waste.

However, there’s rarely any reason for major concern as long as you put your users first. Google Search is a search engine that will always try to show the content that’s most relevant to the user’s search—and that’s exactly what you need to keep in mind when working with SEO!

And even though it’s not always easy to gain insight into Google’s exact algorithms, we do know that there are several factors that can have a significant impact on a website’s rankings in search results—and that are therefore worth considering when you embark on your SEO journey.

Past experience shows that the following factors help determine where your website appears in the search results:

SEO is a long-term, ongoing process that never really ends. Google’s algorithms are complex and constantly changing, and competition for the top spots on Google can be fierce.

If you've ever tried your hand at search engine optimization, you know that it can be difficult to make sense of an SEO strategy. But you have to start somewhere.

An SEO strategy might look like this:

If it’s an older website, it might be a good idea to start by prioritizing the technical aspects of SEO. It’s incredibly important that your website functions properly, since otherwise it can negatively impact your search engine optimization—and then, unfortunately, all your hard work won’t amount to much.

That’s yet another reason why it makes sense to consider whether to hire an agency to handle your SEO—it requires technical expertise.

  • HTTP URLs
  • 4xx error
  • Content – Duplicate and Missing Content
  • Missing and Duplicate H1 Tags
  • Missing and Duplicate SEO Titles
  • Missing and Duplicate H1 Tags
  • Images larger than 100 KB
  • Page Speed
  • Missing canonical tags
  • Missing and Duplicate Metadescriptions

In short, you can get a complete overview of technical SEO pitfalls that can hinder your ability to achieve better organic keyword rankings in search engines.

Of course, there are many other areas you can look into more closely, but some are more urgent than others. Remember, the goal is to get an overview right from the start so you know what requires the most of your attention.

Screaming Frog - 4xx errors

When conducting a keyword analysis, you need to go all out. Think of it as a data-driven brainstorming session where you identify all the keyword combinations that might be relevant to your business. It’s a good idea to consider the following questions when embarking on an exciting keyword analysis.

  1. What products and services do we offer?
  2. Which products or services are most important to us?
  3. Which products or services are in the highest demand?

Although it’s a good idea to include as many keyword combinations as possible in your keyword analysis, that doesn’t mean you should immediately try to optimize them all at the same time. It’s difficult to determine how many to start with, as it depends on how competitive the keywords are—however, most people start by focusing on about 5–10 keyword combinations.

Keyword analysis can start with something as simple as a brainstorming session and your knowledge of your own industry, as well as how your target audience searches. For example, if you’re a dentist with a dental clinic in Østerbro, Copenhagen, keywords such as “dentist,” “dental clinic,” “root canal,” “toothache,” “dental crown,” and so on would be relevant to examine more closely. Since you run a clinic that typically targets local customers, you’ll also want to focus on the locations Østerbro and Copenhagen rather than a nationwide search.

A brainstorming session can be a good place to start. However, we always recommend taking a more data-driven approach.

Tools likeAhrefsandGoogle Search Consolehave everything you need to conduct a thorough keyword analysis.

In Ahrefs, for example, you can generate a report of the keywords your website already ranks for and, at the same time, see the estimated monthly search volume and your ranking for each of them. This allows you to get an overview of where there is room for improvement. You can also perform competitor analysis using the “Content Gap” feature. Here, you can enter your own domain and compare it with one or more competitors’ domains to get an overview of relevant keywords they rank for but you don’t. 

In the example below, I've compared a wine retailer's website with that of a competitor. 

Ahreds offers many useful features for search analysis

If you have a website that includes a lot of landing pages with well-written, descriptive content for all your services and/or products—well, then you can get started on SEO right away. However, very few people have that.

There’s one thing you’re allowed to “steal”—and that’s the layout. Explore the websites that appear on the first page for your target keyword and see how comprehensive their content is. Do the landing pages have 2,000 words? Well, then you’ll most likely need to have the same amount.

In addition, it’s important to optimize your keywords on the pages where it makes the most sense—and mixing in too many topics and keywords is rarely a good strategy. Let’s use the dentist example again. Google prioritizes user-friendliness, and it’s confusing for users if they have to read about orthodontics on the same page where they find information about tooth extraction.

Always keep in mind that if YOU’re unsure whether something makes sense, Google will certainly be unsure as well. Later in this guide, you’ll find more information on how to write effectiveSEO content.

The goal of search engine optimization is visibility, which ultimately should lead to more sales or inquiries through your website. That’s why it’s a really good idea to set up proper tracking of visitors, inquiries, sales, newsletter sign-ups, and other important metrics that can provide insight into the results of your SEO efforts.

Google Analytics and Google Tag Manager are indispensable tools here. Analytics can provide you with virtually every type of data imaginable about your website, while Tag Manager serves as the link between your site and your Analytics account, ensuring that you’re tracking the right metrics.

The quantity and quality of links from other sites that point to your site have a significant impact on your website’s authority—and thus your rankings on Google. That’s why it’s important to continuously work on acquiring relevant links to your site. This practice is known as“link building.” In other words, links from sites with content similar to yours.

Links from generic private blogging networks, shady casino sites, and sleazy porn sites are not relevant links. Relevant links, on the other hand, are those from industry associations, suppliers, partners, bloggers, sponsors, press releases, and reviews.

So even though the number of links matters, quality is what counts most. It’s better to have one relevant link than 10 irrelevant ones.

There’s no such thing as resting on your laurels when it comes to SEO. Google’s algorithm is complex, and competition for certain keywords can be fierce. That’s why it’s important to continually evaluate the results of your efforts.

For example, do you rank poorly for certain keywords? Does your website not generate enough leads? Or do your users otherwise fail to engage with your content as desired?

These are questions you need to ask yourself on an ongoing basis, and they provide the basis for potential optimization.

On-page and off-page

Although there are several hundred internal and external factors that can influence your SEO strategy, the optimization process is often divided into two broad categories: on-page and off-page SEO.

Build Authority on Google Through Link Building

In short, link building is about creating links between pages—this can be across subpages within a single domain (internal link building) as well as across domains (external link building). The latter, in particular, is a key focus for SEO specialists, as links from other websites can be seen as a kind of recommendation to Google and other search engines that a website is worth visiting. 

In other words, links from other websites serve as a signal of authority to Google and other search engines—and are therefore an important part of search engine optimization. You can read more about this in ourblog post on link building.

Link Building

What is outbound link building?

Outbound link building is used to link to external sites that are meaningful and relevant to your visitors. Outbound link building has been used in several places throughout this guide—can you spot them? Psst… you’ll find an outbound link under “What is outbound link building?”, among other places.

What is external link building?

 The purpose of external link building is to drive traffic to your website so that Google considers your website relevant and valuable. You can build links through websites, blog posts, social media, and other Google services, such as Google My Business—you can read ourguide to Google My Business here.

Link building, however, is about more than “just creating links.” Before you know it, you may have quickly spent a lot of time, effort, and—not least—money on external link building without seeing any results. Just like with all other aspects of SEO, you need to have your analysis in order before you get started.

How do you get external links to your website?

External link building can be divided into two categories: free and paid.

Check a domain—is it valuable?

You've now found the landing page you want to link to and identified a domain from which it would be beneficial to get links. Now it's time to check the quality of the domain.

Take a look at the following:

  1. DR (Domain Rating) – How high is it?
  2. Content – Does the website's content match YOUR content?
  3. Credibility – Is the website credible?

At Amplify, we primarily use Ahrefs when we need to gain insight into every nook and cranny of a website, since the tool collects virtually every type of data. It’s a true dream tool for an SEO specialist.

To give you an overview, we ran a test ongoogle.dk, as you can see in the image below. It’s clear that Google (naturally) has an incredibly high DR, a lot of backlinks and referring domains, as well as organic traffic.

Feel free to check the domain authority when you're looking for backlinks

Avoid Being Penalized by Google

If you want to avoid violating any of Google’s many guidelines, we recommend that you thoroughly familiarize yourself with what constitutes good and natural link building. If you want to be sure it’s done right, you can also hire a marketing agency that specializes in marketing. In the worst-case scenario, a violation could result in your domain being banned from Google’s index.

At Amplify, our SEO team specializes in link building, and we only use relevant and credible sites that provide value!

Useful SEO Tools

Why is it important to use the right tools?

Optimize Your Website's Page Speed

Are you data-driven, just like our own SEO specialists? If so, don’t miss out on reading one of our previous posts, which takes an in-depth look at the aforementioned SEO tools and more.

Do you know that feeling of standing in a one-meter-long line at your local supermarket, eagerly waiting to be allowed to pay for your groceries? It’s kind of the same feeling you get when you visit a website that loads slowly. Very few people have the time or patience to wait for that. By analyzing and optimizing your website’s load time, you can achieve greater success on Google.

Google Rewards Good Page Speed

Did you know that Google rewards websites with fast load times? In 2021, Google rolled out an update to its algorithms that made a good page and user experience a key ranking factor in Google’s eyes. Website usability across different devices, good page speed, and secure landing pages were some of the main areas of focus.

Choose your favorite tool

There are a wide variety of tools available that can provide you with information about your website's speed, as well as an overview of which areas need a little extra attention.

Tools you can use:

  1. PageSpeed Insights

Get the visibility you deserve

Are you ready to take a closer look at your website’s load time? Of course you are! We’ve put together a list of 5 areas you should pay special attention to when you start optimizing your site’s speed.

YouTube SEO – SEO Is More Than Just Google

In Denmark, we often equate search engine optimization with Google optimization. But YouTube is also a search engine—according to some sources, the second-largest in the world —and therefore it can also be worthwhile to optimize YouTube videos for search engines if you have a YouTube channel to complement your website.

YouTube SEO can, to some extent, improve your rankings in the video giant’s own search results, but also in Google’s results—both in regular search results and in video results. Google owns YouTube, which is why its search engine also ranks YouTube videos relatively highly. 

How to Do SEO on YouTube

Just as there are best practices for SEO on websites, you should also be able to check off a number of items on a checklist if you want your YouTube videos to rank higher.

We went through all the points ourselves when we published the short explainer video in January—the one you’ll find at the top of this guide. That means that, as of this writing, we’re in the top 10 of Google’s video results for the search term “SEO”—and also in YouTube’s top 10 for the search term “what is SEO.”

And don't worry, what we've done isn't a trade secret—here's the list.

An example of search engine optimization on YouTube

In the video at the top of this article, I give a brief introduction to the three elements of SEO. The video is on YouTube, and true to the motto “practice what you preach,” my colleagues and I have, of course, gone through the list above.

And YouTube has certainly rewarded us with good rankings—here for the broad keyword “search engine optimization”—feel free to also try searching for “SEO” and “what is SEO” on YouTube. Does our video show up in your search results?

Try searching for the various keyword combinations in Google's video results, too. Do we show up there?

SEO vs. Google Ads

What’s the right marketing strategy for your business? It’s one of the most common questions in digital marketing—and given the many options available, it’s understandable to feel unsure!

It’s ALWAYS a good idea to invest in your online presence—as an SEO and Google Ads agency, we can definitely attest to that.

The long-term investment that creates value

SEO is a long-term marketing strategy that’s definitely worth the time if you know what you’re doing. The optimization process is time-consuming, and you need to master everything from copywriting and link building to the technical optimization of your website.

Countless studies have shown that people are more likely to click on an organic search result than on an ad. Organic search results are perceived as more trustworthy—do you scroll past the paid ads yourself?

A Smart Investment, If You're an Expert
Advertising on Google is often described as a short-term marketing strategy compared to SEO. However, that's not the case if, like our Google Ads specialists, you put your heart and soul into every ad you create.

If you want a well-functioning Ads account and a Google Ads strategy that delivers a positive ROI, don't hesitate to contact a marketing agency.

SEO and Google Ads – The Perfect Match

You can never go wrong by investing in both SEO and Google Ads—but it requires that you have the time and budget for it. These are two of the biggest areas in digital marketing, and if you manage to tap into the potential of both, you’ll definitely see the results.

When Does SEO Benefit from Google Ads?

SEO can greatly benefit from the extensive data available in Google Ads. Since search engine optimization is a process that sometimes requires patience, this can provide a better and faster overview of which keywords are worth investing in.

If you use the same keyword combinations in your paid ads as you do in SEO, past experience also shows that your search engine optimization gets a boost. Some would say that’s a better love story than Jack and Rose in *Titanic*.

When Does Google Ads Benefit from SEO?

Google Ads works much like an auction house, but price isn't the only decisive factor at Google.

Google prioritizes user experience—what’s known as “quality results” —and this also applies to paid ads. This means you can’t be sure of securing a Page 1 ranking, even if you spend the most money. This is where SEO plays a key role, as it involves optimizing page speed, landing pages, copywriting, titles, meta descriptions, and more.

An American marketing agency took a closer look at the interaction between SEO and Google Ads, and the study showed that better-quality results (due to SEO) led to lower click prices and more traffic to both organic and paid ads. Read more about the study here.

Are you convinced that your business needs to be visible in both paid and organic search results? At Amplify, we’re ready to take your marketing strategy to new heights!

Can an agency improve your SEO?

It’s not impossible to succeed with SEO on your own—but it’s a time-consuming process that requires you to stay on your toes. There are many different areas you’ll need to master—including copywriting, communication, and the ability to troubleshoot and fix technical errors on a website.

There are many benefits to working with a marketing agency if you want to drive growth and realize your business’s potential.

  1. Most marketing agencies can handle ALL of your marketing activities.
  2. You save on the cost of a marketing employee (which is typically much higher than the cost of using an agency).
  3. You'll avoid the costs of training a new employee.
  4. You can get expert advice and assistance in identifying business opportunities.
  5. You don't need to spend money on all kinds of SEO programs.
  6. You'll receive a customized, specialized, and targeted SEO strategy.
  7. You'll be assigned a specialist with several years of experience in SEO who knows which strategies work.
  8. You can focus on your core competencies.
  9. An agency that specializes in SEO is always up to date on the many changes to Google's algorithms.

SEO – How Do I Choose the Right Agency?

There are countless marketing agencies offering the same services, so it’s understandable that it can be difficult to decide which one to choose.

Choose an agency where…

Does SEO work?

It certainly does, if you do it the right way. Together with my colleagues, I’ve been working intensively on SEO for amplify.dk for the past year and a half, and the growth in our organic traffic speaks for itself.

We’ve nearly sextupled our SEO-generated traffic in a year and a half. But it’s also taken time and effort. In other words, you can’t expect immediate results from SEO—that’s where Google Ads comes in. But with the right effort, SEO can be an extremely important source of long-term online success.
