If you woke up this week and noticed your traffic looking different, you are not alone. Google officially launched the May [year] Core Update on May 21, and the SEO community has been watching the fallout closely ever since. This is the second broad core update of [year], and based on the early data, it is hitting with real force. If you run a blog, a content site, or any property that relies on organic search traffic, this is the most important thing to understand right now.
Google released the May [year] core update on May 21, the company’s second core update of [year]. It follows the March [year] core update, the March [year] spam update, and the February [year] Discover update. The rollout may take up to two weeks to complete. That means the rankings you see today are not final. The dust will not settle until roughly the first week of June, so do not make panicked decisions based on what you are seeing this week.
How bad is it compared to previous updates?
Context matters here, and the context is genuinely alarming for sites that have not kept up with Google’s content quality expectations. During the March [year] core update rollout, 79.5% of URLs in top-three positions shifted — up from 66.8% in the December 2025 update. In the top 10, 90.7% of URLs shifted, compared to 83.1% in December.
That is extraordinary volatility. Think about what that means: nearly 80% of pages that were ranking in positions one through three in March moved. That is not a small tweak to the algorithm. That is a near-complete reshuffling of the search results for an enormous number of queries.
The March [year] Core Update was, without exaggeration, one of the most aggressive in the recent cycle: nearly 80% of the results in the top 3 changed position, and close to one in four pages in the top 10 fell completely out of the top 100. The May [year] update arrives as the next chapter in that same story.Marketing4eCommerce
The May update is arriving just 43 days after the March rollout ended. That is an unusually tight cadence, and it means sites that were still recovering from March are now getting hit by a second wave before they have had time to diagnose what went wrong.
What is getting penalized
Early community observations point to thin informational content, AI-generated sites without meaningful human editing, and affiliate-review properties as the categories absorbing the sharpest movement in the early days of the May rollout.
Google is now rolling out the next generation of its core ranking systems powered by advanced Gemini-based quality models, with emphasis on surfacing original, helpful, people-first content and penalizing automated, ad-bloated content.
That phrase — “Gemini-based quality models” — is significant. Google is no longer just using traditional signals to assess content quality. It is using its own AI models to evaluate whether content is genuinely useful, or whether it is constructed to rank. The sophistication of that evaluation has jumped considerably in [year], which is exactly why sites that were flying under the radar with passable thin content are now getting caught.
What is actually getting rewarded
Google increasingly favors content that demonstrates real expertise and practical understanding of a topic. Articles that include real examples, case studies, expert insights, or first-hand experience are becoming more competitive than generic rewritten summaries. Websites focusing deeply on one niche are building stronger authority signals.
This is not a new message from Google — they have been saying it for years. The difference in [year] is that the algorithm is finally sophisticated enough to enforce it consistently. Experience-based content, tested recommendations, genuine opinions backed by real knowledge — these are things AI cannot easily replicate, and they are exactly what Google’s quality models are being trained to find and reward.
What to do right now — and what to avoid
The most important thing: do not make rapid content changes during an active rollout. Data is volatile and unrepresentative during an active rollout period. Any changes you make now will be evaluated under an algorithm that is still shifting — making it almost impossible to know whether your changes helped or hurt.
Wait for the rollout to complete, then audit carefully. Pull your Search Console data for the past 90 days. Look at which pages dropped and ask honestly: does this page have something genuinely useful that a reader could not get elsewhere? Is it based on real knowledge or real testing? Does it answer the query better than the pages that outranked it? The answers to those questions are your content roadmap.
???? Señal de Reddit: r/SEO is extremely active this week. The threads reporting the biggest drops are consistently from site owners running large volumes of templated content, whether AI-generated or just thin and formulaic. The threads reporting gains are from smaller sites with genuine niche authority and a consistent editorial voice.
???? Señal de Twitter/X: SEO professionals on X have been sharing volatility screenshots all week. The most-retweeted analysis points to a pattern: sites that diversified into email newsletters, YouTube, and social audiences before the update are shrugging off the traffic hits. Sites that had 90%+ dependence on organic search are the ones in crisis mode.
???? Señal de Quora: “My blog traffic dropped 70% this week — what should I do?” is appearing in large numbers on Quora’s digital marketing section. The most upvoted answers consistently say the same thing: do not touch your site during the rollout, do a proper content audit once it settles, and start building traffic channels that are not 100% dependent on Google.
The broader lesson from this update is not a new one, but it keeps getting proven true. The sites that are resilient through core updates are the ones that are already building genuine authority, real audience relationships, and content that exists to serve readers rather than to rank. That is the only strategy that does not get disrupted every time Google ships a major update.
