Google's September 2026 Spam Update Is Rolling Out

Key Takeaways

• Google released the September 2026 spam update on 24 September 2026 at 09:15 PDT. It applies globally and to all languages.
• The rollout may take up to two weeks, so rankings can keep moving into early October. Judge the impact after it finishes, not during.
• It is a spam update, not a core update: it targets sites that break Google's spam policies.
• Search Engine Roundtable counts it as the fourth spam update Google has announced this year.

What Happened

Google posted the update on its Search Status Dashboard: "Released the September 2026 spam update, which applies globally and to all languages. The rollout may take up to two weeks to complete."

There was no blog post and no list of what changed — as usual for spam updates, the dashboard entry is the announcement. Search Engine Roundtable noted it is the fourth spam update of 2026, and had reported ranking volatility on 23 and 24 September, around the time the update was released. Tracking tools cannot tell you which movement came from the update and which from anything else, which is one more reason to wait for the rollout to finish.

Industry Impact & Ranking Volatility

Spam updates improve Google's automated systems for spotting pages that break its spam policies. The policies are public, and several are the ones that catch ordinary businesses rather than obvious spammers:

• Scaled content abuse — many pages produced mainly to rank, whether by AI, templates or people, with little value of their own.
• Doorway abuse — sets of near-identical pages, such as city pages that only swap the place name.
• Site reputation abuse — third-party content published on a trusted site to borrow its ranking strength.
• Expired domain abuse — buying an old domain to rank unrelated content on its history.
• Link spam — links bought or exchanged to manipulate rankings.

If your site follows those policies, a spam update should not hurt it. If a section of your site relies on one of those patterns, this is the kind of update that finds it. For local businesses the risk is usually thin location pages; for stores it is usually thousands of templated product or category pages. That is why local SEO city pages need real local content, and why large catalogues need the checks in the technical SEO checklist.

A drop after a spam update is algorithmic. It is not a manual action, and it will not appear in Search Console's Manual actions report — but that report is still the first thing to check, to rule a manual action out.

SearchPrex Action Checklist

1. Mark 24 September in your reports. Add an annotation in GA4 and note the date against your Search Console data.
2. Wait for the rollout to complete before drawing conclusions. The Search Status Dashboard will show when it has finished.
3. Check Manual actions in Search Console to rule out a manual penalty, which needs a different fix.
4. Compare like with like. Once it completes, compare the two weeks after with the two weeks before, by page type, to see which sections moved.
5. If a section fell, audit it against the spam policies — especially scaled content and doorway pages — and improve or remove what does not meet them. See our Google algorithm updates timeline for this year's earlier updates.
