Google Algorithm Updates 2026: Every Confirmed Update, Dated

The 2026 update record, at a glance

Google confirmed six updates between January 1 and August 27, 2026. Every row below is dated from Google's Search Status Dashboard or the trade reporting that tracked it. Unconfirmed volatility — the "unnamed update" chatter that fills SEO forums most weeks — is deliberately excluded, because a ranking movement nobody can attribute is not something you can plan against.

February: the first Discover-only update Google has ever announced

The February 2026 Discover core update ran from February 5 to February 27. It matters for two reasons. It was the first confirmed Google update of the year, and it was the first time Google has ever announced an update aimed at Discover alone rather than at Search.

Google described it as a broad update to the systems that surface articles in Discover, with three stated aims: showing users more locally relevant content from websites based in their own country, reducing sensational content and clickbait, and surfacing more in-depth, original and timely content from sites with demonstrated expertise in a subject. It launched for English-language users in the U.S. and expanded to other countries and languages afterwards.

If a publisher's Discover traffic moved in February and their Search traffic did not, this is almost certainly why — and the two channels should be diagnosed separately from here on.

March: a 19-hour spam update, then a 12-day core update

Two distinct updates landed three days apart, and conflating them produced a lot of bad diagnosis.

The March 2026 spam update started March 24 at noon PT and was complete by 7:30 AM PT the next morning — roughly 19 and a half hours, the shortest confirmed spam update rollout in the Search Status Dashboard's history. Rollouts that short give you no window to react while they are in flight.

The March 2026 core update then began March 27 and completed April 8 at 6:12 AM PDT: 12 days and 4 hours. Both the announcement and the completion notice ran only through the Search Status Dashboard and Search Central's accounts on X and LinkedIn. There was no companion blog post — a pattern that repeated in May.

May: the second core update, with volatility front-loaded

The May 2026 core update began May 21 and was confirmed complete on June 2 — 12 days, almost exactly matching March's duration. The volatility profile is the useful part: the biggest movement hit on May 23, only two days after the announcement, with a second spike around May 30 and further movement in the final 24 hours.

That front-loading is a trap. A site that checked its rankings on May 24, saw a drop, and started making changes was reacting to a partial rollout — and any changes made mid-rollout are almost impossible to attribute afterwards. Google's own guidance remains that there is no specific fix for a core update, and that the largest position changes tend to arrive with the next core update rather than in the gap between them.

June and August: spam updates at a higher cadence

Google announced the June 2026 spam update at around noon ET on June 24, globally and across all languages, saying the rollout would take a few days. The August 2026 spam update followed on August 18 and was marked complete on August 21 — about two days and 16 hours.

Three confirmed spam updates in eight months is a meaningfully higher cadence than the one or two per year site owners had adjusted to. Google did not publish a list of targeted techniques for any of them.

The distinction between spam and core is not academic. A core update is a reassessment of how well content serves a query — there is no violation to fix. A spam update enforces the spam policies, so a loss there points at something specific and identifiable: scaled content abuse, site reputation abuse, cloaking, expired-domain abuse, link schemes. Broadly "improving quality" is the wrong response to a spam-update loss; finding the violation is the right one.

What the 2026 pattern actually tells you

• Rollouts are getting shorter. Both core updates took 12 days; the spam updates took hours to days. The old advice to wait two weeks before drawing conclusions now roughly matches a full core rollout, but overshoots a spam one considerably.
• Announcements have moved off the blog. Dashboard and social first, documentation notes second, blog posts rarely. The FAQ rich result removal in May was announced only as a note on a documentation page.
• Discover is being managed separately. February's update makes Discover its own diagnostic surface, not a by-product of Search rankings.
• AI surfaces are now measured separately too. June's Search Console generative AI reports gave site owners their first native visibility data for AI Overviews and AI Mode — covered in our AI SEO news deep-dive.

If your traffic moved, work in this order

1. Date the drop precisely in Search Console, then match it against the table above. A drop that does not line up with a confirmed update is more often a technical or seasonal problem than an algorithmic one.
2. Separate the surfaces. Search, Discover, and now AI features report differently. A Discover collapse in February and a core-update loss in March call for completely different work.
3. Classify the update type. Spam update means find the violation. Core update means reassess whether the page is genuinely the most useful result for the query it targets.
4. Wait for the rollout to complete before acting, using the Search Status Dashboard rather than third-party trackers to confirm.
5. Change one thing at a time. With updates now arriving roughly every six weeks, bundled changes become permanently unattributable.
