March 2026 core update
First core update of 2026, described by Google as a regular update to better surface relevant, satisfying content.
What changed
Google ran the March 2026 core update from 27 March to 8 April, three days after a spam update. The announcement used Google's now-standard framing about surfacing relevant and satisfying content, with no new guidance or policy changes. The twelve-day rollout was shorter than most recent core updates.
Timing
Rollout began 27 March 2026. Google declared it complete on 8 April 2026, 12 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
