Google released two core updates in 2026: the March core update, completed on April 8, and the May core update, which began on May 21. Both pushed visibility away from aggregator sites and towards brands with real expertise. No core update has been confirmed since May, and SEO analysts say the next one is overdue.
If your traffic moved this year, this guide explains why. If it hasn't yet, it explains how to get ready.

What Were the Google Core Updates in 2026?
Google confirmed two broad core updates in 2026. The March 2026 core update finished rolling out on April 8. The May 2026 core update started on May 21, during Google I/O week. There was also a February Discover core update and a March spam update, making 2026 a busy year for rankings.
| Update (2026) | Key dates | Notes |
|---|---|---|
| February Discover core update | February | Affected Google Discover |
| March spam update | March | Spam-focused |
| March core update | Finished April 8 | Within Google's two-week estimate |
| May core update | Started May 21 | Second core update of 2026 |

Who Won and Who Lost in the 2026 Core Updates?
In 2026, first-party brand websites and government domains gained visibility, while aggregators and user-generated content platforms lost ground. The pattern suggests Google is rewarding sites that are the real source of a product, service or fact, rather than sites that summarise others.
An analysis by Amsive, led by VP of SEO and AI Search Lily Ray, looked at over 2,000 domains using SISTRIX data after the March update. It found aggregators lost US visibility while brand and government sites gained, as reported by Search Engine Journal. Ray described the trend as “the push toward elevating the actual companies.”
- Winning: a college's own course page, a clinic's own treatment page, a brand's own product page
- Losing: “top 10 colleges” lists, directory listings and thin comparison sites
- At risk: pages written mainly to be cited by AI, with little real experience behind them
On the May update, SEO consultant Harpreet Singh Chatha suggested it may have targeted sites over-optimizing for AI citations. Read why trust signals matter so much in our guide to EEAT SEO.
When Is the Next Google Core Update?
Google has not announced the next core update. But no core update has been confirmed since May 2026, which is a long gap by Google's usual rhythm. One forecasting model, built by SEO strategist Dan Taylor for Search Engine Journal, estimated a 96.8% chance of a major core update within the month.
According to a November 2026 roundup by WTF is SEO, the same model gave a 91% chance of an update within 90 days. Search Engine Roundtable also reported heavy ranking volatility chatter on October 20 and 21, though Google confirmed nothing.
- Google announces core updates on its Search Status Dashboard.
- Rollouts usually take about two weeks.
- You should wait at least one full week after completion before judging the impact.
How to Prepare for or Recover From a Google Core Update
You prepare for a core update the same way you recover from one: make every important page more helpful, more original and more clearly written by someone with real experience. There is no quick technical fix. Google says core updates reassess content quality across the web, so the work is in the content itself.
- Find the pages that matter. Use Google Search Console to list your top 20 pages by clicks.
- Check each page for first-hand proof. Add real examples, photos, results and the name of the person who did the work.
- Cut or merge thin pages. Several weak pages on one topic hurt more than one strong page.
- Update dates and facts. Old prices, stats and screenshots signal neglect.
- Strengthen your author and About pages. Show credentials, experience and contact details.
- Measure after, not during. Compare two weeks before and two weeks after the update completes.
Don't forget AI search
Core updates now affect more than blue links. The same quality signals decide who gets cited in AI answers. Learn how to rank in AI Overviews, and why many SEOs now say good GEO is mostly good SEO.
| Do | Don't |
|---|---|
| Add first-hand experience and proof | Mass-publish AI content to fill gaps |
| Merge thin pages | Chase every volatility rumour |
| Update facts and dates | Change everything during a rollout |
| Show real authors | Hide who wrote the page |
Frequently Asked Questions
What is a Google core update?
A Google core update is a broad change to Google's main ranking systems. It reassesses how helpful and trustworthy content is across the web. Unlike spam updates, it doesn't target specific tricks. Rankings can rise or fall for pages that did nothing wrong.
How many core updates did Google release in 2026?
Google confirmed two broad core updates in 2026: the March core update, which finished on April 8, and the May core update, which began on May 21. There was also a February Discover core update and a March spam update.
When is the next Google core update?
Google hasn't announced it. No core update has been confirmed since May 2026. One forecasting model by SEO strategist Dan Taylor estimated a 96.8% chance of a major update within the month as of early November, but Google alone confirms timing.
How do I recover from a Google core update?
Improve the helpfulness and originality of your important pages. Add first-hand experience, remove or merge thin content, update outdated facts and show real authors. Recovery often shows during the next core update, not immediately.
Does a core update mean my site was penalised?
No. A core update is not a penalty. Google re-evaluates content across the web, so other pages may simply have been judged more helpful than yours. Focus on improving quality rather than looking for a single error.
Conclusion
Google's 2026 core updates rewarded real brands and punished thin summaries. Another update looks overdue. Use the waiting time well: strengthen your top pages with first-hand proof, clean up thin content and show who is behind your site. That protects you in blue links and in AI answers.
