Google Ranking Volatility: What to Do When Rankings Swing

Google search rankings swung hard again on October 27, 2026, the fourth unconfirmed round of volatility in 11 days after earlier swings on October 16, October 20 and 21, and October 24. It came soon after the September 2026 spam update, which ran from September 24 to October 8. Google hasn't confirmed any of these rounds. At the same time, AI Overviews now appear on more than 80% of Google searches by Search Engine Roundtable's read of recent data, and a Semrush study found them on 88% of 400 tracked commercial keywords in August 2026, up from 45.75% a year earlier. Reading the swings is harder than usual because Ahrefs says Google shows altered results to suspected data scrapers, affecting 5% to 20% of results depending on the provider. Marketers should check Search Console before they react, avoid big site changes during an unconfirmed update and focus on review, comparison and best X for Y pages, where AI Overviews now show up most.
