What is Sitemap XML?

An XML file that lists all important URLs on a website, helping search engines discover and crawl content efficiently.

A sitemap.xml file provides search engines with a roadmap of your website's content. Each URL entry can include last modification date (lastmod), change frequency (changefreq), and relative priority (priority 0.0-1.0). Sitemap indexes reference multiple sitemap files for large sites (50,000 URL limit per file). Dynamic sitemaps are generated programmatically from database content โ€” listing all product pages, blog posts, category pages, and static pages. Submit sitemaps to search engines via Google Search Console and Bing Webmaster Tools, or reference them in robots.txt. Regular sitemap updates help search engines discover new content quickly and understand site structure.
