Several times a year, Google makes significant changes to its ranking systems. These core updates can cause a site's rankings and traffic to fluctuate sharply within a few days. However, they always follow the same pattern: an official announcement, a rollout period of about two weeks, and then an analysis phase.
How does Google announce a core update, and how should you react when it affects your site?
What is a Google core update?
A core update is a set of "significant and broad changes" made to Google's algorithms, according to its own documentation. Its goal is to surface more useful and reliable content. It affects organic results as well as Google Discover.
Google releases three to four per year: four in 2024 (March, August, November, December), three in 2025 (March, June, December), and two as of the time of writing for 2026 (March and May). Between these major updates, Google deploys smaller core updates that it does not announce because they are less noticeable.
A core update is different from a spam update, which targets practices that violate Google's policies, such as black hat SEO. It is also distinct from a manual action, which is the only type of penalty that Google notifies you about directly in the Manual Actions section of Google Search Console.
How Google announces a core update
Google announces every core update in the same way:
- The Search Status Dashboard : this is the official source. Each update is listed there with its launch date and time, then updated at the end of the rollout with its total duration.
- Google Search Central accounts : the announcement is shared on LinkedIn and X, often a few minutes after it is posted to the dashboard.
The message is almost always identical. For the May 2026 core update, Google stated that it was a regular update designed to better surface relevant and satisfying content from all types of sites, and that the rollout could take up to two weeks. No new recommendations accompanied the announcement.
A point of caution: SERP tracking tools regularly detect spikes in volatility without a confirmed update. As long as Google has not posted anything on the Search Status Dashboard, it is not an official core update.

What should you do during the rollout?
During the two-week rollout, rankings can fluctuate significantly, rising and then falling back. Reacting impulsively by modifying pages or deleting content is like trying to fix a problem that isn't yet measurable.
Best practice is to:
- note the start date in a Search Console annotation to easily locate the period in your reports;
- monitor the rankings of strategic keywords without making any urgent changes;
- continue with planned projects, as a rollout is no reason to freeze the entire site.
How do you measure the impact of a core update in Search Console?
Google recommends waiting until the rollout is complete, then waiting at least one full week before comparing that week to the week before the update began.
In the Performance report, you should then:
- analyze Web, Image, Video, and News search types separately;
- identify the pages and queries that have lost the most clicks;
- distinguish between minor variations and actual drops. According to Google, a page moving from position 2 to position 4 does not require drastic action. A page moving from position 4 to position 29 warrants an in-depth analysis;
- check the impact by market for an international site, using the Search Console multi-country filter.
TheSEO KPIs . The key metrics to watch remain the clicks, impressions, and rankings of pages that generate revenue or leads.

How do you recover after a core update?
A core update most often re-evaluates the site as a whole, not just an isolated page. Google therefore advises evaluating the entire site objectively, if possible with an outside perspective, before working on the most affected pages.
The factors that matter:
- Content quality : verify that each page that has dropped better satisfies the search intent than the pages now ranking higher, and rewrite or restructure it if that is not the case. An SEO content strategy Claire avoids creating pages that compete with each other.
- Trust signals : identified author, cited sources, update date, real-world experience. These are the criteria E-E-A-T.
- Low-value pages : content with no traffic, duplicate, or outdated pages weigh on the overall perception of the site. However, Google reminds us that deletion should remain a last resort.
- The technical foundation : a core update generally does not stem from a technical issue, but a technical SEO audit removes the obstacles that would prevent a ranking recovery.
Google warns against quick fixes, such as removing a page element because it might be bad for SEO. Only real improvements for users produce a lasting effect.
How long does it take to recover from a core update?
According to Google's documentation, some improvements take effect in a few days, while others require several months. If nothing changes after a few months, you often have to wait for the next core update.
Gary Illyes from Google provided more precise estimates during Search Central Live in Barcelona on October 2, 2026: three to six months in a typical case, and up to a year in the longest cases. These figures come from a participant's report; Google did not publish them. However, they confirm that a recovery within a few weeks remains the exception.
Conclusion
A core update is predictable in its format: an announcement on the Search Status Dashboard, two weeks of rollout, and then a one-week waiting period before analysis. The key is not to react too quickly, and then to work on the quality of the site as a whole rather than looking for a quick fix.

FAQ
Is there a Google core update happening right now?
Google's Search Status Dashboard indicates in real time whether an update is currently rolling out. As of the time of writing, the last core update was in May 2026, which finished on June 2, 2026.
How many core updates does Google deploy per year?
Generally three to four: four in 2024, three in 2025. Google also deploys smaller core updates between major updates without announcing them.
How long does the rollout of a core update last?
Google generally announces a rollout of about two weeks. For the last five core updates, the actual duration has varied from 12 to 18 days.
Is a core update a penalty?
No. A core update does not target any specific site: it re-evaluates content, and a drop means that other pages are deemed more useful. A penalty, or manual action, is notified in Search Console.
Should you modify your site during a core update?
It is better to avoid hasty changes during the rollout, as rankings are still fluctuating. Substantive projects already planned can continue, and analysis should be done one week after the rollout ends.
