Google rolls out the May 2026 Core Update
Google confirmed a broad core update starting May 20, 2026, with a multi-week rollout. As always, it re-evaluates content quality and relevance site-wide rather than targeting any single signal.
What changed
Core updates reassess how Google ranks existing, indexed content. They don't penalise pages — they re-weight relevance and quality across the board, so visibility can move up or down even without site changes.
Indexing angle
A core update is about ranking, not indexing — but pages that were borderline “crawled, not indexed” often shift either way as quality signals are re-evaluated. It's a good moment to clean up thin and duplicate pages.
Don't make rash changes mid-rollout. Wait for it to finish, then focus on content quality — and make sure your strongest pages are actually indexed so they can benefit.
