February: the first Discover core update
“Released the February 2026 Discover core update for English language users in the US.”
— Google Search Status Dashboard, February 2026 Discover update
Google said the update was designed to improve the overall quality of Discover, with plans to expand to all countries and languages later. It affects Discover feeds, not standard web rankings, so a drop in Search traffic in February 2026 should not be blamed on it. Check the Discover report in Search Console separately. Our posts on Google Discover and Discover traffic drops go deeper.
March to June: two core updates and a new policy
The March 2026 spam update finished in under a day, and the March 2026 core update began three days later on 27 March, finishing on 8 April. Because the two were so close, March losses need careful analysis; see overlapping updates analysis.
In April Google announced that back button hijacking, manipulating browser history so users cannot return to the previous page, falls under its malicious practices spam policy. Enforcement started on 15 June 2026, through manual actions or automated demotions. Google noted that such behaviour can come from third-party libraries or ad platforms, so even sites that never wrote such code should check. Our back button hijacking audit explains how.
The May 2026 core update ran from 21 May to 2 June. As with all core updates, Google's guidance is that most sites don't need to worry, and that those affected should assess whether their content overall is helpful, reliable and people-first.
June to October: spam updates and the EEA change
Short global spam updates followed in June and August, then a much longer one from 24 September to 8 October. Google did not say what any of them targeted. In between, Google changed how its site reputation policy works in the EEA: flagged pages there may be categorised as separate from the main domain rather than being subject to a manual action's ranking impact, while manual actions still apply elsewhere.
Other 2026 Search changes worth knowing
These are not ranking updates, and we have not verified all of them against Google's own documentation, so treat them as reported:
- 24 February: a short serving issue during which Google could not show some or all results, per Wikipedia's timeline.
- 27 May: Preferred Sources introduced in AI Overviews and AI Mode, per Wikipedia's timeline.
- 3 June: new controls for site owners over how content is used and shown in AI Overviews and AI Mode, per Wikipedia's timeline.
- 31 August: a worldwide opt-out control for AI Overviews and AI Mode which, according to Wikipedia, does not affect traditional rankings.
