December 2022 helpful content update

What changed

Google released the second helpful content update on 5 December 2022 and confirmed completion on 12 January 2023. The most significant change was that the system now applied globally in every language rather than only English. Google also said its classifier had been improved, and the rollout ran across the holiday period alongside a link spam update.

Timing

Rollout began 5 December 2022. Google declared it complete on 12 January 2023, 38 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
