The Index Coverage report in Google Search Console is a tool that allows website owners to see how many of their pages are indexed by Google. This report provides information on the number of valid pages that were discovered by Google during crawling, as well as any issues that may be preventing some pages from being indexed.
The report is divided into three main sections: Error, Valid with warnings, and Valid.
Error: Pages that have been excluded from the Google index due to an issue, such as a crawl error or a robots.txt file that blocks Googlebot.
Valid with warnings: Pages that have been indexed by Google, but have issues that may impact their visibility or ranking. For example, a page may have valid structured data but it is not complete.
Valid: Pages that have been indexed without any issues.
The Index Coverage report can help website owners identify and fix issues that may be preventing their pages from being indexed by Google, which can improve their website’s visibility and ranking in search results. Additionally, the report can be useful for identifying and removing duplicate or low-quality pages that may be diluting the strength of the website.
