XML Sitemap

A structured file listing the canonical URLs on your site so crawlers can discover them efficiently.

Definition

An XML sitemap is a file (typically at `/sitemap.xml`) that lists your site's important URLs along with optional metadata like last-modified dates and change frequency. It gives crawlers a reliable map of pages that might not be reachable through normal link-following, such as new content or deeply nested pages.

Why it matters for AI visibility

Crawlers with limited budget will prioritize pages they can discover quickly. A clean, accurate sitemap ensures your most important brand, product, and editorial pages are known — rather than discovered only if a crawler happens to follow a link to them.
