AEO Glossary
A sitemap.xml is an XML file that lists all the URLs on a website along with optional metadata (lastmod, changefreq, priority). It is placed at the site root (yourdomain.com/sitemap.xml) and submitted to search engines and AI crawlers to help them discover and prioritize content.
AI crawlers use sitemaps to prioritize which URLs to visit first and how frequently to check for updates. A comprehensive sitemap ensures that all your important pages - especially newly published content - get crawled promptly. Without a sitemap, AI crawlers rely solely on link discovery, which can miss pages that are not well-linked internally.
Generate a sitemap using your CMS, a plugin (Yoast, RankMath), or a static site generator. Include all canonical URLs for public-facing content. Set lastmod to the actual last-modified date of each page (not today's date for every page). Reference your sitemap in robots.txt as Sitemap: https://yourdomain.com/sitemap.xml. Submit it to Google Search Console and Bing Webmaster Tools.
