If you have looked at Google Search Console, you will have seen a “Sitemaps” section. It is easy to wonder whether you need to do anything with it, and whether your site is missing out if you do not.

This guide explains what a website sitemap is, what Google says about whether you need one, and how to submit it. Everything here comes from Google’s own pages on sitemaps and on building one.

What is a sitemap?

A sitemap is a file that lists the pages, videos and other files on your site. Search engines read it to crawl your site more efficiently. It can also tell them which pages you think matter and when a page was last updated.

Do you need one?

Google’s answer is: usually not, if your pages are well linked. It says that if your site’s pages are properly linked, Google can usually discover most of your site.

Google says a sitemap is more likely to help if:

• your site is large,
• your site is new and has few links from other sites, or
• you have lots of video, image or news pages.

Google says you might not need one if your site is small, which it describes as about 500 pages or fewer that you want in search results, and your pages link to each other properly. Our guide to internal links shows how to link pages well.

If your site is built on a platform such as WordPress, Wix or Blogger, Google says it likely already provides a sitemap, so check before creating one.

What a sitemap does not do

A website sitemap helps Google discover pages. It does not guarantee that every page in it will be crawled or indexed. Google calls submitting one “merely a hint”. If a page is missing from Google, a sitemap will not fix a problem such as a noindex tag. Our guide on why a website is not showing on Google lists what to check.

What goes in the file

Google supports three formats: XML, RSS or Atom feeds, and plain text with one address per line. XML is the most flexible. Google’s rules include:

• The file must be UTF-8.
• Use full, absolute addresses, including `https://`, not short paths.
• List the main (canonical) version of each page you want in results.
• One file can hold up to 50,000 addresses or 50MB. Larger sites split them up.
• Google says it ignores the `priority` and `changefreq` values.
• Google uses the `lastmod` date only when it is consistently and verifiably accurate, and it should show real changes to the main content, not a copyright year update.

How to submit it

1. Put the sitemap at the top level of your site, for example `yourdomain.com/sitemap.xml`. Google says a sitemap only affects addresses at or below its own folder unless it is submitted through Search Console.
2. In Google Search Console, open Sitemaps, enter the address and submit. The report shows when Google last fetched it and any errors. Our guide to what Google Search Console is explains the rest of the tool.
3. You can also add a `Sitemap:` line to your robots.txt file.

If the report shows errors, our guide to Search Console errors explains what the messages mean.
