June 2025 core update: dates, what changed and what to do

What Google changed#

Google announced the June 2025 core update on the Search Status Dashboard on 30 June 2025 with a one-line entry: “Released the June 2025 core update.” It did not publish a separate Search Central blog post describing what changed.

Google describes core updates in general as “significant, broad changes to our search algorithms and systems,” made several times a year to keep delivering helpful and reliable results. Nothing Google published names a specific system or type of content this update changed.

When it rolled out#

The Google Search Status Dashboard logged the release on 30 June 2025 at 07:34 PDT with the note that “the rollout may take up to 3 weeks to complete.” Google posted on 17 July 2025 that the rollout was complete as of that day, a total of 16 days and 18 hours. No other confirmed ranking update overlapped it.

What is known about its impact#

Google did not publish impact figures for this update. Its own framing is that core updates “don’t target specific sites or individual web pages,” and that pages which move down aren’t necessarily bad; other pages may simply serve the searcher better. Treat any percentage you see attributed to this update as a third-party estimate, and check its method.

What site owners should do#

With no update-specific post, Google’s standing core update guidance is the advice that applies:

• Confirm the rollout has finished, then wait at least one more full week.
• Compare the week after with a week before the update began, not with the rollout window.
• A small drop (position 2 to 4) needs no drastic action; a large, sustained drop warrants a site-wide self-assessment against Google’s helpful content questions.
• Avoid quick fixes. Improve content in ways that help readers; delete content only as a last resort.
• Recovery can take several months and may not show until a later core update.

How to check whether it affected you#

In Search Console, set the Performance report to a date range spanning June to August 2025 and compare clicks for the week before 30 June with the week starting 18 July. Look at Web, Image, Video and News search types separately, as Google recommends. The Google Algorithm Updates timeline lists every confirmed update with its dates, so you can rule out other rollouts before attributing a change to this one.
