Google September 2026 Spam Update: What Changed

When did the September 2026 spam update start?

Google began rolling out the September 2026 spam update on 24 September 2026. The Google Search Status Dashboard logged the release as applying globally and to all languages, with Google noting the rollout could take up to two weeks to finish.

Is the September 2026 spam update finished?

Yes. The dashboard entry states plainly that “the rollout was complete as of October 8, 2026,” according to the Google Search Status Dashboard. That’s a run of just over two weeks, in line with Google’s own estimate. As of this writing (18 October 2026), the update has been fully out for ten days.

What changed

Google hasn’t published specifics on which spam types this particular update targeted. Its general spam updates documentation explains that these releases are improvements to the automated systems — including SpamBrain, Google’s AI-based spam-detection system — that run continuously in the background. Google’s guidance is consistent across spam updates: sites that notice ranking changes should check their spam policies for compliance, since violations can lead to lower rankings or removal from results.

Google also repeats a specific warning for link-related spam updates: if a site’s rankings were inflated by spammy links, removing those links afterwards won’t restore the lost ranking benefit, because that benefit was never legitimate to begin with. It isn’t stated whether this September update specifically targeted link spam, so site owners shouldn’t assume that applies here without checking their own link profiles.

Trade coverage picked up on the update’s close in mid-October, with outlets including DesignRush and ALM Corp confirming the rollout had finished, and others examining its effects on specific sectors such as dental and manufacturing SEO. The detail of any industry-specific impact wasn’t set out in the material available here, so treat those angles as reporting on individual cases rather than confirmed general patterns.

What SEOs are seeing

Community discussion on r/bigseo was mixed and largely anecdotal. One thread asked whether sites hit by Google’s earlier June spam update were seeing any change — recovery or further decline — during the September rollout, but no consolidated results were shared in the material reviewed.

A second thread reported an unusual pattern on a small coupon site: daily Search Console impressions reportedly rose from around 780 a day before the update to roughly 1,900 a day during the rollout window (peaking near 5,000 on 7 October), before dropping to about 600 a day once the update completed — with clicks staying flat throughout. The same user said one page jumped from position 55 to position 6 for a branded coupon-code query, racking up thousands of impressions but no clicks. This is a single, unverified case from community chatter, not a confirmed Google pattern, but it’s worth noting if you’ve seen similar impression spikes without click growth.

What to do if your rankings changed

If your traffic moved during the 24 September–8 October window, start by checking whether the shift correlates with the rollout dates rather than something else happening on your site at the same time. Review your content and links against Google’s spam policies, and if link spam is a possibility, read up on link schemes. Sites relying heavily on third-party or low-quality content at scale should also check Google’s site reputation abuse guidance.

Genuine fixes won’t show results overnight — Google says it needs to observe sustained compliance over months before improvements feed through. If you want to see exactly which queries and pages moved during this window, OpenSEO’s open-source rank tracker can help isolate changes tied to the update dates rather than normal fluctuation.
