Google's June 2025 Core Update: What Changed and What to Do
By Jeremy ·
Google's June 2025 core update started rolling out on June 30 and finished on July 17 (a 16-day rollout). The rankings shift was broad, and a few specific signals moved more than usual.
The Rollout Timeline
Google described it as "a regular update designed to better surface relevant, satisfying content for searchers from all types of sites." They say this every time. The language covers a lot without committing to specifics.
The rollout took just under 17 days from start to finish. During that window, rankings were unstable in ways that made it hard to assess actual impact until the dust settled. If you pulled traffic numbers mid-June or in the first week of July, you were probably looking at noise. The cleaner read came after July 17.
What E-E-A-T Changes Mean in Practice
The biggest signal shift in this update was toward E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness. Google updated its Quality Rater Guidelines around this period to weight these signals more heavily, particularly for YMYL content.
In practical terms, the changes reward content backed by genuine first-hand experience. A review written by someone who actually used the product is being treated differently from one that aggregates secondary sources. Author credentials and bios got more weight, but only when the credentials are specific and verifiable. Generic "team of writers" bylines aren't doing the work that a named author with a demonstrable background does.
Publication dates and source citations also factor in more directly. AI-generated content isn't penalized outright, but content that was generated and published without a knowledgeable human reviewing and editing it before it went live is showing up in the losers column.
Google's E-E-A-T documentation has the full framework if you want to read what the quality raters are actually evaluating.
Which Sites Got Hit
Health, finance, and legal sites took the most visible hits. YMYL content has always been the highest-scrutiny tier, and this update reinforced that. Sites in those niches that relied on AI-generated content or thin coverage without clear author credentials saw significant drops.
E-commerce also had a rough rollout. Part of that was E-E-A-T, but Core Web Vitals played a role too. Slow page loads and poor mobile performance correlated with ranking losses in retail categories in a way that was more pronounced than previous updates.
The zero-click trend got harder to ignore. Zero-click searches grew from 56% to 69% of queries, meaning more searches are being answered by Google's own SERP features without a click going anywhere. Ranking well is still valuable, but the traffic you'd expect from a given ranking position has gone down for informational queries where AI overviews are appearing.
SpamBrain, Google's spam detection system, now identifies 200 times more spam sites than it did in previous versions. Sites that were relying on low-quality link building or thin content patterns to stay indexed are seeing manual and algorithmic action.
What to Actually Fix
If your site took losses in this update, the generic advice about "improving content quality" won't get you anywhere specific. Here's what the data from this update actually points to.
First, audit which pages lost traffic and whether those pages reflect genuine experience with the subject. If a content team wrote about topics they haven't actually engaged with, that shows in the writing, and it's showing up in rankings.
Add author information where it's real. If Jeremy wrote the article, his name and a brief credential note matter. If a contractor wrote it under a generic byline, that's weaker. Don't add fake credentials. Google's quality raters cross-reference these things.
Fix Core Web Vitals if they're lagging. The Lighthouse score for your slowest pages is a starting point. Largest Contentful Paint over 2.5 seconds and Cumulative Layout Shift above 0.1 are the specific thresholds that matter.
Remove or substantially rewrite thin content rather than leaving it indexed. Pages with fewer than 400 words covering a topic that warrants more depth are a drag on domain-level quality assessment.
On the zero-click issue: the percentage of searches that end without a click isn't something you can fix through SEO. What you can do is prioritize content types where users are still clicking through, primarily longer guides and original research, and build email or direct channels that aren't dependent on organic click-through at all.
