How to fix: sitemap.xml reachable
Part of the Technical SEO pillar on the Site Integrity Index.
Why this matters
Sitemap.xml tells crawlers which URLs exist and how recently they changed. It's the difference between being discovered and being missed.
Background
A reachable /sitemap.xml is the fastest way for search crawlers to discover new + updated pages. Without it, crawlers rely on link discovery — slow + incomplete for large or new sites.
