Google confirmed the September 2026 spam update on September 24, its fourth spam update of the year after March, June, and August. It applies globally and across all languages, adds no new spam policies, and — unusually — may take up to two weeks to complete rather than the roughly two and a half days the August update needed.

Google confirmed the September 2026 spam update on September 24, 2026. The Search Status Dashboard logged it beginning at about 9:15 a.m. Pacific, with Google's standard release note: "Released the September 2026 spam update, which applies globally and to all languages. The rollout may take up to two weeks to complete." As with previous spam updates, there was no accompanying blog post explaining it.
This is the fourth spam update of 2026, after ones in March, June, and August — making this the most active year for Google spam updates in several years. The headline difference this time is the timeline. The August update finished in about two days and sixteen hours; Google's own estimate for this one is up to two weeks. Asked to confirm the two-week figure wasn't a typo, John Mueller said it's "likely to take longer than some of the previous ones." A "may take up to two weeks" estimate is a ceiling, not a promise — previous updates have finished inside their stated windows — but it means the ranking volatility a spam update produces can now run for the better part of a fortnight before the dust settles.
Google did not disclose what this update specifically targets, and it introduced no new spam policy types — its existing spam policies remain the rules a site is judged against. SEO industry reporting indicates the update does not target link spam specifically. Spam updates re-score sites that violate those policies rather than re-weighting general quality signals the way a broader core update does. The policy content teams should read most closely is scaled content abuse: producing large volumes of pages that add little value for users "no matter how it's created." Google's standing guidance is that recovery from a spam-related drop can take months, because its automated systems need time to confirm a site has changed its practices. Confirm the live rollout status and any policy wording on Google Search Central, which is the primary source.
Look at the pattern, not the single event: March, June, August, and now September. Spam updates have become quarterly weather, and any business whose traffic swings on each one has built its house on a channel it doesn't control. The fix isn't to out-guess the next update — it's to make Google Search a bonus surface rather than the load-bearing one. A spam update re-scores web pages and nothing else; it has zero say over how a [Persona Shorts](/glossary/persona-shorts) clip, a Listicle Video, a Carousel, or an Email Newsletter performs, because those live where the algorithm being updated has no reach.
[Kompozy](/) is the engine for running that spread on a schedule instead of scrambling for it every time rankings wobble. Feed it one source — a webinar, a podcast, a long post — and it generates the full week: captioned vertical video and face-locked [Persona HeyGen](/) episodes, brand-exact carousels rendered through [HyperFrames](/glossary/hyperframes), infographic posters, a blog article, and a newsletter, every piece written in one voice through your [Persona Brief](/glossary/persona-brief) with a banned-word filter that strips the generic AI-tell phrasing that both readers and quality classifiers penalize. It then schedules and publishes across the eight social platforms plus blog and email from a single queue on [Autopilot](/glossary/autopilot), with a per-post review step so a human finishes anything website-facing in their own voice with real examples — E-E-A-T by construction, not a doorway page. Run that cadence for a quarter and the next spam update stops being a fire drill; it becomes a line you read in an SEO newsletter while your reach keeps compounding on every surface the update can't touch.
Google confirmed it on September 24, 2026, with the Search Status Dashboard logging the start at about 9:15 a.m. Pacific. Google said it applies globally and to all languages and that the rollout may take up to two weeks to complete — notably longer than the August 2026 update, which finished in about two days and sixteen hours.
The substance is the same — global, all languages, no new spam policies — but the timeline is longer. August completed in about two days and sixteen hours; Google estimated up to two weeks for September, and John Mueller confirmed that was intentional, saying it's "likely to take longer than some of the previous ones." It is the fourth spam update of 2026 after March, June, and August.
Only insofar as it violates the spam policies. Google did not disclose a specific target and added no new policies, but the scaled content abuse policy addresses generating large volumes of low-value pages to manipulate rankings "no matter how it's created." AI-assisted content that is original, edited, and genuinely useful is not the target; thin pages mass-produced to blanket keywords are.
Wait for Google to mark the update complete before diagnosing a change, since rankings can keep moving for up to two weeks. If your site was hit, fix the underlying issue — 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 its guidance says can take months.
