Confirmed September 24, the update carries Google's longest spam-update estimate yet — up to two weeks — and SEOs tracked the impact in waves: a first round September 25–27, then a second surge, dubbed “phase two,” beginning September 30. There is no separately confirmed October core update.

Google's September 2026 spam update — confirmed on the Search Status Dashboard on September 24, 2026 — was still rolling out in early October, making it the longest spam-update window Google has run. The release note was the standard one: the update applies globally and to all languages, and the rollout "may take up to two weeks to complete." Google added no new spam policies; its existing policies remain the rules a site is judged against. It is the fourth spam update of 2026, after March, June, and August, and the first to carry a two-week estimate rather than the two or three days those earlier updates needed.
The impact arrived in waves rather than a single hit. SEOs tracking the rollout logged a first round of volatility from September 25 to 27, with Saturday the 26th showing the sharpest movement, then a quieter stretch, then a second surge beginning September 30 and continuing into October 1. Barry Schwartz of Search Engine Roundtable called the renewed movement "phase two"; Glenn Gabe reported hearing from several site owners who said they saw a huge drop land precisely on September 30, and separately, posters on the WebmasterWorld forum reported Google Discover and News traffic vanishing again that same day. One caveat matters: Google logs a single continuous rollout and has not announced distinct phases — the multi-wave framing comes from third-party rank-tracking tools and practitioner reports, not an official Google statement.
There is no separately confirmed October 2026 core update. As of early October, Google's Search Status Dashboard listed the September spam update as the only active ranking event, still without a completion time. If Google holds to its own two-week estimate, the rollout would finish on or around October 8, though "up to two weeks" is a ceiling rather than a promise. The practical reading for content teams: the volatility a prolonged spam update produces can run for the better part of a fortnight, in more than one burst, before positions settle — so the window for clean diagnosis has not opened yet. Confirm the live status and any policy wording on Google Search Central, which is the primary source.
The instinct during a two-week rollout is to open the blog and start deleting or rewriting pages. Resist it. Google tells you to wait until an update finishes before diagnosing a drop, and gutting a post mid-rollout only destroys the one thing you can still measure once it settles. The productive move while the volatility runs is to stop staring at rankings and extend the reach of the content you already have onto surfaces this update cannot score.
That is the specific job [Kompozy](/) does. Point it at a blog article that may be dipping and it turns that single post into a week of off-Search distribution — a captioned [Persona Short](/glossary/persona-shorts), a brand-exact [Carousel](/glossary/hyperframes), a Quote Graphic, platform-native text, and an [Email Newsletter](/glossary/output-buckets) — each held to one voice by a [Persona Brief](/glossary/persona-brief) and pushed across the eight social platforms plus blog and email from a single queue. A per-post review step keeps a human on anything website-facing, so the blog itself stays original and edited rather than the kind of thin, mass-produced page a spam update acts on. When the rollout finally completes and you sit down to diagnose, a traffic dip on one channel reads as a line item, not a crisis — because the ideas kept earning attention everywhere Search wasn't deciding.

Yes. Google confirmed it on September 24, 2026 and estimated the rollout could take up to two weeks — its longest spam-update window, versus two or three days for the March, June, and August updates. As of early October it had not been marked complete on Google’s Search Status Dashboard, which is the primary source to check for the final status.
It is how the SEO community described a second wave of ranking volatility that began around September 30, after an initial round of movement on September 25–27. Barry Schwartz used the phrase, Glenn Gabe reported site owners emailing him about sharp drops on September 30, and WebmasterWorld forum posters separately reported Discover and News traffic vanishing that same day. Google itself logs a single continuous rollout and has not announced distinct phases — the multi-wave pattern comes from third-party rank tracking.
Google's guidance is to wait until an update is marked complete before diagnosing a change, because rankings can keep moving for the full two weeks. If a site was genuinely hit, the fix is to remove or substantially improve thin, mass-produced pages and stop the practice that triggered it, then give Google's automated systems time to re-evaluate — which can take months. Panic-editing mid-rollout destroys the data you need to diagnose.
No. As of early October 2026, Google's Search Status Dashboard lists no October core update. The active ranking event is the September 2026 spam update, which began September 24 and was still rolling out into October. Sustained volatility in early October is attributable to that ongoing spam update rather than a new, separately confirmed update.
