What Site Owners Should Know
Spam updates are aimed at sites that violate Google's spam policies, though collateral movement can occur with any ranking change. Search industry commentators noted volatility at several points during the rollout. One prominent SEO consultant suggested early on that Google might be responding to attempts to manipulate AI Overviews, but Google has not confirmed a motive.
If your traffic changed after September 24, SEO practitioners advise checking whether the drop began before the rollout, comparing against Google's published spam policies, and ruling out technical issues or a separate core update. Google's last core update ran from May 21 to June 2, 2026.
Google said it would record the completion on its ranking release history page.
