The Google Search Console’s coverage report tells you when a page is valid with a warning. What do these warnings mean? What should you do about them?
These pages appear in Google. Are you sure you want them to? Google is guessing that you want them to appear in search results. Of course, “appearing” and “ranking” are two different things.
There is only one warning in this report: Indexed, though blocked by robots.txt. This means Google added it to its index (and could be found) even if you don’t want it to be.
Google is telling you that they’ve indexed your content although it appears to be blank (without content). You need to decide if this is intentional before you know what do do about it.
If you don’t want Google to see your content, you can ignore this warning. It can’t see the content that you don’t want it to see. It simply appears to be a blank page. This is a false-alarm.
