To audit an XML sitemap for Google Search indexing, you can validate XML correctness, check URL reachability via HTTP 200 responses, verify canonical consistency, and detect noindex conflicts or redirect issues.

To generate an XML sitemap for a large website, you can create a sitemap index that splits content by type, enforces the 50,000-URL protocol limit, and documents the structure for search engine indexing.

Sitemap URLs might not show up in Google Search results if they contain noindex tags, canonical mismatches, redirect chains, or non-200 HTTP status codes, all of which can be identified through a comprehensive sitemap audit.

You need to use a sitemap index instead of a standard XML sitemap when your website exceeds the 50,000-URL protocol limit, requiring content-type splitting and multiple sitemap files for accurate search engine indexing.

To check if your robots.txt file is blocking your XML sitemap, you can perform a robots.txt discovery audit to ensure search engines can successfully access and parse your sitemap references without restrictions.

The correct way to format lastmod values in an XML sitemap is to ensure they reflect accurate last modification timestamps, which helps search engines prioritize and crawl recently updated content efficiently.
