# Google Begins Rolling Out May 2026 Core Update on May 21, Second Broad Algorithm Overhaul of the Year With Two-Week Timeline

*2026-05-22 18:01 UTC · Technology · 1 min read*

> Google launched its May 2026 broad core update on May 21 with a two-week rollout, the second algorithm overhaul of the year after the March update.

Google started rolling out the May 2026 broad core update on May 21, the company confirmed on its Search Status Dashboard. It is the second broad core update of the year after the March 2026 rollout, which completed in 12 days.

Google said the deployment may take up to two weeks to finish and offered no accompanying blog post or new guidance, matching its March playbook. The change affects all site types rather than targeting specific content categories or policy violations, so SEO professionals should expect significant ranking volatility through early June.

Search Engine Journal and Search Engine Land both urged site owners to avoid knee-jerk content changes during the rollout and to wait at least one week after completion before analyzing Search Console data. Google reiterated its standard line that a negative ranking impact does not necessarily mean a page has anything wrong with it.
