Sizable decrease in amount of pages indexed, however no drop in clicks, impressions, or ranking.

[Jason-Reid]

Hi everyone,

I've run into a worrying phenomenon in GSC and im wondering if anyone has come across something similar. Since August, I have seen a steady decline in the number of pages that are indexed from my site, from 1.3 million down to about 800,000 in two months.

Interestingly, my clicks/impressions continue to increase gradually (on the same pace they have been for months) and I see no other negative side affects resulting from this drop in coverage.

In total I have 1.2 million urls that fall into one of three categories, "Crawled - currently not indexed", "Crawl anomaly", and "Discovered - currently not indexed"

Some other notes - all of my valid, error, and excluded pages are https://www. , so I don't believe there is an issue with different versions of the same site being submitted. Also, my rankings have not changed so I tentatively believe that this is unrelated to the Medic Update.

If anyone else has experienced this or has any insight to the problem I would love to know.

Thanks!
