Sitemaps: An SEO tool for documentation

Sitemaps allows us to inform search engines about URLs that are available for crawling and communicate them additional information about each URL of the project:

• when it was last updated,
• how often it changes,
• how important it is in relation to other URLs in the site, and
• what translations are available for a page.

Read the Docs automatically generates a sitemap for each project that hosts to improve results when performing a search on these search engines. This allow us to prioritize results based on the version number, for example to show stable as the top result followed by latest and then all the project's versions sorted following semver.
