IndexNow 422: Unprocessable Entity
Resolve IndexNow host, keyLocation, and URL-list consistency errors.
Updated September 2, 2026
Common causes
- Mixed hosts
- The urlList contains more than one hostname.
- Host mismatch
- The host field differs from the URL hostname, including www versus apex.
- Invalid key location
- keyLocation belongs to another hostname or does not correspond to the key.
Diagnosis
Normalize the URL list, group it by exact hostname, and generate one request per group.
Retry policy
Correct the host boundaries before retrying. Splitting by protocol is unnecessary, but splitting by hostname is mandatory.
