The whole "low CTR = bad content" take is outdated. Been seeing this across my B2B campaigns - rankings can be solid, but CTR gets hammered by AI overviews, featured snippets, Reddit blocks, shopping carousels, you name it. One query I track dropped from 8% CTR to 1.2% after Google started pulling a direct answer from a snippet. Content hadn't changed.
What I'd still audit: intent mismatch (targeting "how to" when user really wants "best tools"), weak meta titles that don't signal value, or the worst - cannibalisation where two similar posts compete for the same query. Also check if the SERP itself has become a self-contained answer engine. If it has, that's a structural problem, not a content one.
CTR analysis these days is basically noise unless you isolate the SERP features eating your share. Painful but necessary.
