Google has updated the Google Search Console Index Coverage report to be more accurate. This process began July 14th and ended August 1st and is now showing in the reports. Because of this you may see changes in your reported index coverage, Google said. Google had to estimate data between July 14th and ended August 1st but going forward the data should be more accurate.
Google wrote on the data anomalies page:
July 14 - August 1, 2018 and onwardThe Index Coverage report switched to a new, more accurate system. Because of this, you may see changes in your reported index coverage. This does not reflect any changes in your site, but a more accurate accounting system.
The system switch began on July 14 and finished on August 1, during which we were not able to record index coverage data. Index coverage data between July 14 to August 1 was estimated from the known August 1 values.
You should see the "note" in the reports, here are some screen shots:
I see changes in my reports but some see larger changes.
@christian_wilde has been complaining about issues and now says the reports look good, this is after Google updated the report:
Yesterday:
Seems like the "Index coverage" report on the new Search Console hasn't been updated since July 14th for all the sites I have access to. Is it a bug? @JohnMu @methode @dannysullivan @rustybrick pic.twitter.com/hUVJQVwd96
