Google’s John Mueller explained why a valid sitemap may not always be used by Googlebot. Even if technically correct, Google may prioritize site content, internal linking, and crawl signals over the sitemap. This highlights that while sitemaps remain useful, they are not the sole driver of indexing efficiency.
In a recent discussion, Google’s John Mueller addressed confusion around sitemap errors in Search Console. A user reported that despite their sitemap being technically valid—returning a 200 response code, proper XML structure, and indexing permissions—Google still displayed fetch errors.
Mueller clarified that Googlebot may choose not to rely on a sitemap if site content and internal linking provide stronger crawl signals. This means that even a perfectly valid sitemap can be bypassed if Google determines it doesn’t add unique value to the crawling process.
SEO experts note that while sitemaps remain a best practice, they should be seen as supporting tools, not guarantees of indexing. Strong site architecture, clear navigation, and fresh content often outweigh the role of a sitemap in modern SEO.
