Version courte :
The May 2026 core update caused heavy volatility, with nearly 80 percent of top results shifting.
It hit aggregators and boosted brands, official sources, and data-rich pages.
A core update is a reassessment, not a penalty.
Le motif
Google is rewarding pages that originate value over ones that repackage what already exists. If your content is a reworded version of the same sources everyone cites, you are exactly what lost ground. Original data and first-hand experience held or gained.
Ne panique pas
If you dropped, it does not automatically mean you broke a rule. It usually means another result now looks more helpful or more clearly tied to real expertise than yours.
The recovery move
This is calibration, not a frantic technical audit. Look at the pages that fell and ask whether each has a reason to exist beyond a keyword. I have watched bloggers on X waste weeks tweaking title tags after a core update when the real fix was content that had nothing a reader could not get elsewhere. Strengthen depth, cut the thin pages, and rankings tend to follow on the next refresh.
