Google September 2026 Spam Update: What to Check
Google's September 2026 spam update ran from September 24 to October 8. Here is what we know, what Google has not said, and what to check in your data.
Google's September 2026 spam update started on September 24 and finished on October 8, according to coverage of Google's Search Status Dashboard. That is about two weeks, and the longest of this year's four spam updates. If your traffic moved in that window, you now have a clean period to analyze.
What happened and when?
Google posted the rollout on its Search Status Dashboard on September 24, 2026 at 9:15 a.m. Pacific, and said it could take up to two weeks. The update applies globally and to all languages. The completion note says the rollout was complete as of October 8, 2026.
For scale, the March, June and August spam updates ran for about 20 hours, two days and three days, per the same coverage. This one took 13 days and roughly 15 to 16 hours, depending on who counted.
One caveat: we could not open the dashboard directly while writing this, so the dates above rest on several independent write-ups of it. Check the dashboard itself before you quote them in a report.
What has Google said about targets?
Very little. Google described it as an update aimed at sites that violate its spam policies, and as far as we can tell it did not name specific techniques or announce new policies. So any article telling you exactly which tactic got hit is guessing.
Recovery is slow too. Spam-related demotions can take months to clear, which is a reason not to react to day-three charts.
How do you tell if you were affected?
Do this in Search Console, not in a rank tracker:
- Set the date range to September 24 to October 8 and compare it with the previous 14 days. Better, compare with the same weekdays so weekends don't distort the picture.
- Split by page type: blog, product, programmatic or templated pages. Spam updates tend to cluster on one pattern, so a drop on one folder tells you more than a sitewide dip.
- Check Manual actions in Search Console. A spam algorithm change is separate from a manual penalty, and a manual action would show up there.
- Compare clicks and impressions separately. Falling impressions with stable click-through rate points at lost rankings. Falling clicks with stable impressions is more likely a SERP layout change.
Reports from site owners are mixed, and early anecdotes are noise, not a verdict.
A measurement warning
Search Console's Performance report has had delays recently. Wait for the data to catch up before you draw conclusions.
What would we do now?
- Audit pages you published at scale in the last year. Thin, near-duplicate or mass-produced pages are the usual suspects in any spam policy review.
- Read Google's spam policies once, end to end, and mark anything on your site that sits close to the line.
- Don't rewrite your whole site because of one week of data. Fix what is clearly weak, then recheck in a few weeks.
