Google June 2025 Core Update
Google’s June 2025 core update began rolling out on 30 June 2025 and completed on 17 July 2025, a rollout of just under 17 days. It was the second broad core update of 2025, following the March update.
Multiple data providers, including Semrush, Similarweb, and SISTRIX, flagged it as one of the more significant core updates in recent memory. Search Engine Land reported that the consensus across tracking tools placed it well above average for volatility.
Scale of the volatility
Over 16% of pages holding top-10 rankings after the update had not ranked in the top 20 before it started, according to Semrush tracking data. That churn rate was the highest recorded in four years. For context, the March 2025 update produced meaningfully lower top-10 displacement than June.
The update appeared to have at least two distinct waves of effects, with ranking movements continuing to compound across the rollout rather than settling after an initial shift.
What changed
The June update continued the direction established in March: topical authority and E-E-A-T signals carried more weight, and YMYL categories saw the sharpest movements. Health, finance, and legal content showed the most significant volatility, with some sites that had gained in March dropping sharply in June, suggesting Google continued refining its quality signals rather than simply locking in the March results.
Sites gaining visibility in AI Overviews tended to align with those rewarded by the update, while sites devalued by the update also lost ground in AI-generated answers. The correlation reinforces that the signals driving AI Overview citation and organic ranking are increasingly the same.
HCU recoveries
One notable pattern in the June data: some sites that had lost significant visibility in the September 2023 helpful content update saw partial recoveries. Analysis from SISTRIX and Amsive identified a subset of previously-penalised domains recovering ground, suggesting Google’s reassessment of content quality was producing some rebalancing for sites that had improved since 2023.
These recoveries were partial rather than full, and not universal. Sites that had made only surface-level changes to their content without addressing underlying quality issues remained suppressed.
Notable winners and losers
SISTRIX visibility data showed YouTube and Wikipedia among the largest absolute gainers. Arts, entertainment, lyrics, and fan-content sites broadly performed well. Sportswear, office supplies, and women’s apparel also showed positive movement.
Amazon was the largest single loser by absolute visibility points. Travel aggregators, marketplace brands, and several consumer technology properties declined. The pattern in the losses was consistent with previous updates: intermediary and aggregator operations without differentiated content or proprietary data were most exposed.
What to do
The June update’s HCU recovery patterns are the most actionable signal. For sites still suppressed from 2023-2024 helpful content updates, the evidence suggests Google is continuing to reassess rather than having permanently fixed those rankings. Sustained investment in content quality, not cosmetic adjustments, is what produced the recoveries observed.
For sites affected for the first time, the diagnostic is the same as any core update: whether the content would be considered authoritative by a genuine subject matter expert, and whether it serves the user’s actual need rather than a keyword target.
