What are SEO keywords?
SEO keywords, also known as search terms, are the words and phrases users type into search engines like Google when they're looking for answers, products or inspiration. They act as the link between what you offer and what your target audience is actually searching for. When you work strategically with SEO keywords, you help Google understand what your page is about, so it can be shown in the most relevant search results. In other words, you enable the search engine to match your content with the user's intention behind the search — what's known as search intent.
An SEO keyword can be anything from a single word like “advertising” to a longer phrase like “how to create an SEO strategy”. The difference lies in how specific the search is and what need it covers. It's exactly this connection between search intent and content that makes keyword work a central part of any SEO strategy, and it also ties in closely with content production and digital advertising.
How do you use SEO keywords?
You use SEO keywords as a guide for how you structure and optimise your content. The first step is typically to carry out thorough keyword research. Here, you identify the search terms your target audience uses and assess their relevance, volume and competition. If you work with content marketing, you use the results to define themes for articles, guides and landing pages. In paid search such as Google Ads, the same data can inform which keywords you bid on.
Using SEO keywords effectively isn't about repeating a word over and over, though. It's about creating a natural flow in the language, where the keywords appear in titles, headings, meta descriptions and body copy in a way that makes sense to the reader. Today, search engines assess the content as a whole — they look at whether the page answers a specific question and whether the wording shows that you understand the user's needs. That way, SEO and user-friendliness become two sides of the same coin.
Why you should use SEO keywords
The reason SEO keywords are so central is simple: they increase the chance of your website being shown to the right users at the right time. A well-chosen combination of relevant keywords can help your page rank higher in the search results, which means more organic traffic and more qualified leads without direct advertising costs. When you combine this with a well-thought-out brand universe and a clear digital strategy, keywords can be the element that connects your communication across channels.
You can think of SEO keywords as the foundation of your entire digital presence. They affect how you write copy, how you design your navigation structure and how you set up campaigns on social media. And because users' search behaviour is always changing, you need to keep updating your keyword list to make sure you're still meeting market demand.
What types and variants are there?
Not all SEO keywords work in the same way. Some create awareness, while others lead directly to conversion. That's why it's useful to know the most common variants.
- Seed keywords: The broad words that form the starting point for your keyword research. These can be terms like “marketing” or “strategy”.
- Focus keywords: The specific words you choose for each page. They reflect the page's main theme and typically appear in the title and URL.
- Long-tail keywords: Longer and more detailed phrases like “how to use SEO for content marketing”. They often have less competition but higher relevance for the target audience.
- Branded keywords: Searches that include a brand name. They often signal strong purchase intent, because the user already knows the business.
By combining the different types, you can cover the entire customer journey — from the first information search to the final purchase. In content planning, you can use seed keywords as an umbrella and place long-tail variants in related articles, so you build a coherent body of content.
How do you use SEO keywords in practice?
In practice, the work typically starts with you assessing your existing pages and seeing which words they already rank for. You can then use tools like Google Keyword Planner or Semrush to find new opportunities. They show search volume, keyword difficulty and related searches, which can inspire new themes. You can also analyse competitors' content to uncover where they get their traffic from.
A good approach is to build your website around so-called pillar pages — overarching pages that cover a broad topic — and then link to subpages that each focus on a specific long-tail keyword. In SEO, this is called a content cluster structure, and it helps both users and search engines understand how your pages connect. At the same time, you can use the same keywords in your Google Ads campaigns to strengthen the link between paid and organic visibility.
What should you be aware of?
When you work with SEO keywords, you constantly need to balance data and relevance. A high-volume keyword isn't necessarily the right choice if it doesn't match your target audience's needs or your business's services. That's why you should always test how users respond to content targeting specific keywords, and adjust as you go.
You should also be aware that keyword density matters less to Google today than it once did. The search engine understands context better and assesses whether your content as a whole meets the user's intent. This means you should focus more on creating meaningful content that covers the topic in depth, rather than repeating keywords mechanically. When you combine that approach with ongoing analysis and a clear content strategy, you get the most value out of your SEO keywords — both in the short and the long term.
