February 2023 product reviews update

What changed

Google ran a product reviews update from 21 February to 7 March 2023 and, for the first time, extended the system beyond English to eleven additional languages. Review publishers in those markets experienced the system's effects for the first time. Google's reviewer guidance was translated accordingly but not otherwise changed.

Timing

Rollout began 21 February 2023. Google declared it complete on 7 March 2023, 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.
