Google Spam Update September 2026: What Changed and How to Recover

The September 2026 spam update is a Google ranking update that began on September 24, 2026 and finished on October 8, 2026. Google said it applies globally and to all languages.

Google's Search Status Dashboard lists the run time as 13 days and 16 hours. Its notice said: "The rollout may take up to two weeks to complete." On LinkedIn, Google called it "a normal spam update," per Search Engine Roundtable. Google did not say which spam policy it targets or how many sites it affected.

Interest jumped around the earlier update. Google US searches for "google spam update" reached 880 in August 2026, up from 170 in July, per DataForSEO (pulled Oct 2026). The August peak lines up with the August 18 update. September counts were not in the data yet.

The rollout ran 13 days and 16 hours, about five times longer than August's update. Google's dashboard shows the March, June and August spam updates took 19.5 hours, 2 days 1 hour and 2 days 16 hours.

The gaps between updates also shrank. Counting from the dashboard dates, 92 days passed between March and June, 55 days between June and August, and 37 days between August and September. It was also the first 2026 spam update announced with a two-week window, per Relevant Audience.

John Mueller, who works on Google Search Relations, told Barry Schwartz of Search Engine Roundtable that the long window was real:

The start time was 9:15 a.m. PDT on September 24, per Search Engine Journal, which read it from the dashboard. Google marked the rollout complete as of October 8.

Google lists more than a dozen spam policies, and a spam update can enforce any of them. Sites that break them "may rank lower in results or not appear in results at all," per Google's spam policies.

Google's advice after a spam update is short. Sites that see a change should check themselves against these policies. The route map below turns eight of them into a quick audit list.

The full page also covers hacked content, hidden text and links, link spam, user-generated spam and misleading functionality. Read it all before you decide where to look.

Google has not said. Its notice names no policy, so treat scaled content abuse as one policy to check. Nothing yet proves it caused any drop.

Google defines it as many pages generated "for the primary purpose of manipulating search rankings and not helping users." It does not matter whether people or AI wrote the pages. What matters is whether the pages were made in bulk to rank. Crucially, distinguish scaled manipulation from benign internal repetition: as proven in our research on whether duplicate content gets penalized by Google, normal parameter URLs, facets, and syndicated articles consolidate ranking signals rather than triggering algorithmic penalties.

Site reputation abuse is the other policy many owners ask about. Google describes it as third-party content published on a host site "mainly because of that host's already-established ranking signals." Think of partner coupon pages or sponsored reviews on a trusted domain.

Our view: match the pattern of your drop to a part of your site. If one folder lost traffic and it holds bulk or third-party pages, start there. If the whole site fell evenly, look for a site-wide cause first.

Check dates first, then Search Console. A spam update is automatic, so it shows as a traffic change that starts inside the rollout window. A manual action is a human review, and Google shows it in the Manual actions report.

Google says it uses automated systems and, "as needed," human review "that can result in a manual action," per its spam policies. The two need different fixes, so rule out a manual action before you assume the update caused a drop.

Compare September 24 to October 8 with the 15 days before it, in the same weekday pattern. Then split the change by page group. A drop that starts before September 24 was not this update. Search Engine Roundtable made that point about volatility seen on launch morning.

Recovery has four steps: audit, fix, document and wait. Google gives no guarantee that rankings return, so the goal is to comply with the policies and let its systems recheck.

Audit. List the pages and sections that lost traffic. Mark each one against the policy table above. Be honest about pages that exist to rank rather than to help a visitor.

Fix. Remove, merge or rewrite weak pages. Take down third-party sections that borrow your domain's trust. Fix anything cloaked or hidden. Do not add new bulk pages while you wait.

Document. Keep a dated log of every change. If you have a manual action, you can file a reconsideration request after fixing the issue, as the spam policies describe.

Wait. Track Search Console each week and review each month. Do not undo fixes after one flat week.

SpamBrain is Google's AI-based spam-prevention system. Google says it improves the system from time to time to spot spam better and catch new types, and it calls those improvements spam updates.

Google's spam updates page says changes may help if "our automated systems learn over a period of months that the site complies" with the policies. It gives no fixed date. So a flat result a few weeks after your fixes is normal.

Link spam is different. Google says that when spammy links are removed, any ranking benefit they gave "is lost," and it cannot be regained. If links were your growth source, plan to earn new ones.

The ranking systems guide adds that these systems are "constantly updated to keep up with the latest ways that the spam threat evolves," per Google's ranking systems guide. Treat compliance as ongoing work.

Google has not said, and we found no public study that links this update to AI answer citations. Treat it as a question to measure rather than an assumption.

Your AI answers and your Google rankings are separate scoreboards. If clicks fell after September 24, check whether ChatGPT, Perplexity, Gemini and Google AI still cite your pages. Our guide to AEO vs SEO vs GEO (AEO and GEO) explains how the work overlaps, and our AI visibility benchmarks show what typical citation numbers look like.
