June 2025 core update

Second core update of 2025, running for over two weeks and reported as substantially larger than the March release.

What changed

Google ran the June 2025 core update from 30 June to 17 July. Third-party monitoring recorded it as one of the more forceful updates of the period, with large swings across publisher, health and ecommerce categories. Google announced it with its standard guidance and made no accompanying policy changes.

Timing

Rollout began 30 June 2025. Google declared it complete on 17 July 2025, 17 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
