Sitemap Index Processed but Child Errors: What This Usually Tells You
A sitemap index can be processed successfully while several child sitemaps still fail. That does not mean the sitemap layer is healthy. It means the top-level file worked while problems persisted below it.
Why this pattern appears
Search engines can fetch and understand the index file while individual child sitemaps still return delivery, format, freshness, or content problems. The parent looks healthy, but the estate underneath is mixed.
What to inspect first
Check child sitemap status, content-type, XML validity, freshness, and whether the index points to outdated, empty, redirected, or blocked child files.
What this means operationally
This pattern often points to distributed generation problems: the index is published correctly, but the child files are produced by weaker or less consistent jobs.
