What is a sitemap and do I need one?

A sitemap is a file, usually sitemap.xml, that lists all the important pages of your website. It helps search engines find your pages easily and understand which ones matter. Yes, almost every site benefits from one, and for larger or frequently changing sites a sitemap is nearly indispensable.

How does a sitemap work?

Google sends crawlers that go through your site to discover pages. A sitemap gives those crawlers a direct list of URLs, so they are not entirely dependent on internal links to find everything. A sitemap does the following, among other things:

• Shows which pages you consider important and want indexed.
• Passes along signals, such as when a page was last modified.
• Speeds up the discovery of new or updated content.

The sitemap does not guarantee a spot in the search results, but it does make the path to indexing considerably smoother.

Do I really need a sitemap?

For a small site with a few well-interlinked pages, Google usually finds everything without a sitemap too. But as soon as your site grows, regularly gets new content or has a complex structure, a sitemap becomes important. Pages tucked away deep otherwise sometimes never get discovered at all.

You typically submit the sitemap via Google Search Console, so Google knows where it is. It is a small effort with a clear benefit.

Where does this fit into your SEO?

A sitemap belongs to the technical foundation of your website. It does not solve any content problems, but ensures that the pages you deserve on the merits also get found. Without that foundation, strong content does not come into its own in the search results.

At Customer Impact we do not treat this as a goal in itself, but as part of a site Google can read without trouble. We work exclusively for B2B and make sure the pages that genuinely deliver enquiries get properly indexed, instead of chasing perfect scores in tools that deliver no customers.
