November 2023 core update

What changed

Google launched the November 2023 core update on 2 November and confirmed completion on 27 November. Google said explicitly that it used a different core ranking system from the October 2023 core update, which was an unusual level of detail. Trackers recorded strong volatility, particularly for publishers and review content.

Timing

Rollout began 2 November 2023. Google declared it complete on 27 November 2023, 25 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
