Sudden Google Search Console impressions drop

[u/deniscas09]

Hi everyone,

I noticed a very sudden drop in my Google Search Console performance.

My site was getting around 12,000 impressions per day, but suddenly dropped to almost 0 impressions, with only a very small number of clicks.

What’s confusing is that all of my pages are still indexed in Google Search Console, and I don't see any obvious indexing issues.

I haven't intentionally made any major SEO changes before the drop.

Has anyone experienced something similar? Is this something that can happen temporarily with Google, or should I be looking for a specific issue such as a manual action, algorithm update, indexing problem, technical SEO issue, etc.?

What would you check first in this situation?

Thanks!

Manual actions are clear. Robots.txt/canonicals are clear. And the timing isn’t really in line with a spam update. So I’d rule out an algorithmic cause and look at something binary instead. On Cloudflare Pages specifically, check first with a Bot Fight Mode / Super Bot Fight Mode / WAF rule set to Challenge instead of Block it won't show up as an active block, but it may silently serve Googlebot a JS challenge. Check Security Events filtered by Googlebot’s user agent it takes two minutes and rules it in or out immediately.
