September 2022 core update
Second core update of 2022, arriving days after the first helpful content update finished rolling out.
What changed
Google ran the September 2022 core update from 12 to 26 September, overlapping in the public mind with the recently completed helpful content update. Volatility was moderate compared with the May 2022 release. Google reiterated that core updates and the helpful content system were separate mechanisms with separate timelines.
Timing
Rollout began 12 September 2022. Google declared it complete on 26 September 2022, 14 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
