Why are my 404 pages indexing again?

This report shows the indexing state of all URLs that Google has visited, or tried to visit, in your property. The summary page shows the results for all URLs in your property grouped by status (error, warning, or valid) and specific reason for that status (such as Submitted URL not found (404)). Click a table row in the summary page to see all URLs with the same status/reason and more details about the issue.
