Organic sessions fell off a cliff around the start of the month, roughly 30% and holding. No site redesign, no migration that I know of. GSC impressions are down too, not just clicks, which makes me think it's rankings and not a tracking issue.
I ran /full-site-audit and the health score is 78, no critical flags. Where do I even start narrowing this down? Feeling a bit lost.
Impressions down alongside clicks does point to visibility loss rather than CTR or tracking, so good diagnosis. Here's how I'd isolate it:
/search-console, switch to Pages and compare the last 14 days to the prior 14. Is the drop broad or concentrated in a handful of URLs? Concentrated usually means a few pages lost specific queries; broad usually means a sitewide or algorithmic factor./tools/rank-tracker position history for your money keywords.A 78 health score with no criticals makes an on-site technical cause less likely, so I'd bet on either an algorithm update or a competitor move. Report back what the Pages view shows and we can go deeper.
Ran the Pages comparison. It's concentrated — three blog posts that drove most of my long-tail traffic all dropped together, same topic cluster. So probably an update hitting that content rather than the whole site.
That's a clean diagnosis. One topic cluster dropping together is a classic quality/relevance re-evaluation. Pull those three URLs through the content quality analysis, look for thin or dated sections, and check who overtook you in the SERP — often a competitor published something more thorough. Refresh depth and freshness on those three before touching anything else. You've found your problem.
Been through this exact scenario. Refreshing the cluster with genuinely deeper content brought mine back over about six weeks. Patience but it works.
