What is an XML sitemap?
An XML sitemap is a technical file that helps search engines understand the structure of your website. The file is written in Extensible Markup Language (XML) and contains a list of the URLs you want search engines to crawl and index. You can also add metadata such as the date of the last update, frequency of changes, and priority across pages, so that search engines get a clearer picture of how your content evolves over time.
In other words, an XML sitemap is a kind of map of your website. It shows where the most important pages are located and how they are linked together. Google and other search engines use this information to find new or updated content more quickly, especially when your site has a complex structure or many different types of pages.
A well-functioning XML sitemap complements your other SEO efforts because it ensures that even pages deep within your site structure are discovered. It is, therefore, a technical element that supports your overall search visibility strategy—just as a cohesive strategy for content, links, and user experience does.
How do you use an XML sitemap?
To use an XML sitemap, you generate it, place it correctly on your website, and then let the search engines know where to find it. Most CMS systems, such as WordPress or Shopify, can automatically generate sitemaps using plugins or built-in features, which makes the process simple. Alternatively, you can create it manually if you need more control over which pages to include.
Once you’ve created the sitemap, place it in the root directory of your domain as sitemap.xml. That way, both you and the search engines can always find it in the same place. A good next step is to add the URL to Google Search Console so that Google can confirm that the file has been fetched and is reading the content correctly. You can do the same in Bing Webmaster Tools if you also want to cover that search engine.
Here's what the structure typically looks like:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://www.ditdomæne.dk/side</loc>
<lastmod>2024-02-01</lastmod>
</url>
</urlset>
The most important thing is that each URL is the canonical version you want indexed. The metadata fields such as <lastmod> and <changefreq> This helps search engines understand how often your content changes, but you don't have to fill them all out if it doesn't make sense for you.
That's why you should use an XML sitemap
An XML sitemap is valuable because it maps out your entire website in a way that makes it easier for search engines to understand. This means that pages with limited internal links can still be found and indexed. In other words, you increase the likelihood that all of your content will appear in search results.
This is particularly beneficial for large websites, news outlets, or online stores that frequently update their content. When you add new pages, the sitemap quickly notifies Google of the changes, which can lead to faster indexing. On a more technical level, it helps you and your SEO team maintain an overview of the site structure, which also ties into technical SEO and user experience within the broader context of digital design.
For smaller websites, the effect may seem less noticeable, but an XML sitemap still helps ensure that all content is viewed as a whole. It lays a solid technical foundation that often makes the rest of the SEO work easier.
What types and varieties are available?
There are two main types of XML sitemaps: the standard version and a special “index” version for larger websites.
- Standard XML sitemap – contains a list of URLs and supplementary metadata. It is well-suited for websites with a manageable number of pages, where everything can be included in a single file.
- XML sitemap index – used when you have a large number of URLs, typically more than 50,000. This file serves as a master index that points to multiple sitemaps organized by content type, such as products, blog posts, or landing pages.
In addition, there are HTML sitemaps, which are visible to users and aid in navigation rather than indexing. In the context of SEO, however, XML is the standard because it is tailored to search engines’ needs for structure and data.
How do you use an XML sitemap in practice?
In practice, this involves integrating your XML sitemap into your entire digital operations. You need to ensure that it updates automatically when new pages are added or old ones are deleted, so that the information always reflects reality. If you work with content marketing, where new content is frequently published, the sitemap should be a natural part of your workflow.
You can also use data from Google Search Console to evaluate how search engines interact with your sitemap. Here, you can see how many URLs have been submitted, how many have been indexed, and whether any errors have occurred. You can use this information to identify technical issues that may be hindering your visibility—something that often goes hand in hand with your other SEO efforts and site performance optimization.
What should you keep in mind?
An XML sitemap is only effective if it accurately reflects the structure of your website. You should avoid including pages that are blocked via robots.txt or that have noindex tags. Otherwise, you’ll send conflicting signals to search engines. Also, make sure the URLs in the file are always canonical and return a 200 status code, so you don’t end up with broken links.
Another important point is that the sitemap is not a substitute for a good internal link structure. It merely provides search engines with a map, but they still need to be able to navigate logically through your pages. Therefore, an XML sitemap should be viewed as a technical support tool for your overall SEO strategy—not as a solution in and of itself.
If you work with both SEO and web design, you can think of the sitemap as the structural foundation of your website: the part that search engines see first, while users see what you’ve designed visually. When these two elements work together, you achieve a stronger digital presence and a simpler path to better visibility in search results.
