Index Coverage change in GSC, 19 june 2018?

[vrottenstein]

Hi there!, I have a big website in Latin America and just saw in Search Console that the "excluded urls" rocketed on 19th of June, aprox 40.000 URLs out of 1MM total urls indexed. I checked that on other website and had similar graph also on the same date. anyone with the same issue?

thanks!

Hi Vic, and welcome back from a long gap in posting.

There are a bunch of comments in our June 2018 Updates and SERPs thread [webmasterworld.com...] about large reported drops noticed on June 19, with some suggestions that Analytics has been having problems... but those were mostly comments about reported traffic in Analytics, not about "excluded urls" in GSC.

The GSC is also undergoing an expansion of its performance-related data reporting range to 16-months [webmasterworld.com...] ...and conceivably what you're seeing might be related to those changes.

In any event, did you check any of the specific urls to see what might be going on?

Here's the New Search Console Help page...

Index Coverage Status report
[support.google.com...]

The help page covers all of the usual suspects that might cause pages not to get indexed. Regarding "excluded", it says that following...

Excluded
These pages are typically not indexed, and we think that was your intention.

The likely reasons mentioned for reported spikes all relate to site changes or changes in your CMS. I'm assuming you've double-checked this.

Possibly, again, the number might be relating to the increase in date range on the new GSC. I'm curious if others are seeing this.

Any chance that it is a WordPress site? There would have been a large increase in excluded URLs if it is a WP site that was affected by the attachment URL issue [webmasterworld.com] that affected a large number of sites.

Thank you very much! the spike appears just in GSC and its a clear one-day change. i'm working for two different websites and they are not Worpress and they are not related between them. I supose I will continue my investigation. :) Thank youuuu
