i'm seeing a brutal drop in Google Search Console indexing. went from 448 indexed and 181 not indexed, to 240 indexed and 416 not indexed. almost half my pages got deindexed overnight. no major changes on my end, content still being published regularly. most of the dropped pages are showing as 'Crawled - currently not indexed'.
i know a colleague mentioned the same thing happening to them. Someone else pointed out it's a common issue now as Google fights the flood of AI slop. but that doesn't make it normal. It means Google has decided those pages aren't worth keeping in the index.
if you're in the same boat, here's what's helped me recover: audit the deindexed pages. are they thin, duplicate, or low-value? improve the content - make it genuinely helpful, unique, and comprehensive. Strengthen internal linking to those pages from your stronger ones. and crucially, build external signals - get other sites to link to them and share them. that tells Google these pages have real value.
It's a pain, but it's a quality shake-up. we just have to prove our pages deserve to be there.
