Why does Google deindex pages during a core update?

The premise needs checking first: Google’s core updates page describes changes in how pages rank, and it says nothing about removing pages from the index. When pages leave the index around the time of an update, the cause has to be found in the Page indexing report, which gives a reason for every URL Google has not indexed. Reading those reasons separates an indexing decision from a ranking drop that only looks like one.
A ranking drop and a deindexed page are different findings
| What you see | What it means | Where to confirm |
|---|---|---|
| Fewer clicks and impressions, page still indexed | The page was re-ranked lower | URL Inspection says the URL is on Google; Performance shows lower positions |
| Page listed as "Crawled – currently not indexed" | Google crawled it and has not indexed it; the status does not say why | Page indexing report, then URL Inspection |
| Page listed as a duplicate with another canonical | Google indexed a different URL in its place | URL Inspection shows the Google-selected canonical |
| Page excluded by noindex or an error | Something on your side stopped indexing | Page indexing report reason and the page's own code |
| Page blocked by robots.txt | Google stopped crawling it, which is not the same as removal: a blocked URL can stay listed if links point to it | robots.txt report and URL Inspection |
A page that drops from the first page of results to the fifth is still indexed. Treating that as deindexing leads to resubmitting URLs that were never removed, while the real work is on why the page now ranks lower.
Why pages can leave the index around an update
Google’s core update documentation does not describe indexing at all, so an exclusion that falls in an update week still needs its own reason from the report. A page that adds little beyond other pages on your site or elsewhere can end up as “Crawled – currently not indexed” in any week, update or not, and Google calls that status “a common message for many sites”. When the exclusions cluster on one template or section, look for a technical cause before blaming the update. A page that falls out of the index some time after it was first indexed is a related case: why pages drop out of the index after being indexed.
Deleting pages is not the first move
The core updates page also says “Deleting content is a last resort, and only to be considered if you think the content can’t be salvaged.” Before removing pages that lost traffic, check whether they are still indexed and simply ranking lower, and whether they can be improved or merged into a stronger page. Pages that answer nothing another page does not already answer are candidates for consolidation, and that decision is about what the reader gains, not about the update.
