Malformed sitemap index
When I split into many sitemaps, an index file ties them together. If that index is malformed or points at the wrong locations, the child sitemaps may never be read.
What it is
The index file referencing child sitemaps is invalid.
Why it matters
Child sitemaps may not be discovered.
How to fix it
Fix the index structure.
How to find it on your site
- Validate the sitemap index file as XML.
- Confirm each child sitemap URL in the index loads and is correct.
- Fix any broken references or syntax in the index.
- Submit the index in Search Console and check it reports all children.
Cross-reference to ranking and citation factors
A broken index can hide every child sitemap behind it, so the impact scales with how much you rely on it.
Impact
