The Google September 2026 spam update finished rolling out on October 8, 2026, after almost two weeks. If your traffic moved during that window, now is the right time to look at your data. Not before, and not in a panic.
I have seen the same pattern after every update. A site owner sees a dip, deletes half the blog, rewrites every title, and makes the problem worse. Most of the time the dip was not even caused by the update.
This guide shows you how to confirm whether the spam update actually affected your site, what Google’s spam systems look for, and what to fix if you were hit.
What Happened With the Google September 2026 Spam Update?
The rollout started on September 24, 2026 and ended on October 8, 2026, a run of 13 days and 16 hours according to Google’s ranking update history. Google described it as a normal spam update that applies to all languages and all countries.
Three things made this one different from earlier spam updates this year:
- It was much longer. It was the fourth spam update of 2026. The March, June and August updates each finished within about three days.
- It came in waves. Ranking trackers showed spikes around September 25 to 27, again on September 30, and again from October 4 to 6.
- It was not a link spam update. Google did not name one specific spam type or announce any policy change.
| Spam update | Started | Finished |
|---|---|---|
| September 2026 | September 24 | October 8 |
| August 2026 | August 18 | August 21 |
| June 2026 | June 24 | June 26 |
| March 2026 | March 24 | March 25 |
The waves matter for your analysis. If your traffic dropped on October 5 but not in late September, that still lines up with the update.
Spam Update vs Core Update vs Manual Action
These three get mixed up all the time, and each one needs a different response.
| Type | What it is | Do you get notified? | What to do |
|---|---|---|---|
| Spam update | An improvement to Google’s automated spam detection systems | No | Review your site against Google’s spam policies and fix violations |
| Core update | A broad change to how Google judges quality and relevance across all sites | No | Improve overall content quality and usefulness |
| Manual action | A human reviewer at Google flagged a specific issue on your site | Yes, in Search Console | Fix the issue, then file a reconsideration request |
Start by opening Search Console, then Security and Manual Actions, then Manual actions. If you see “No issues detected”, any drop you saw was algorithmic. A spam update never sends a message, so silence does not mean you are safe.
How to Check if Your Site Was Hit by the Google September 2026 Spam Update
To see if the Google September 2026 spam update affected your site, use Search Console, not a third party traffic estimate. It takes about 15 minutes.
- Open the Performance report and select Search results.
- Compare two equal windows. Set a custom comparison: September 10 to 23 (before) against September 24 to October 8 (during). Later, compare October 9 to 22 against the before window too.
- Look at clicks and impressions together. A spam related hit usually shows a sharp drop in impressions, not just clicks. Clicks alone can fall because of AI Overviews or seasonality.
- Switch to the Pages tab. Sort by click difference. Note whether the loss is site wide or limited to one folder, one content type or one template.
- Check the Queries tab. If you lost rankings for your brand name, that is a serious signal. If you only lost long tail queries on thin pages, the problem is narrower.
- Match dates to the waves. Drops on September 25 to 27, September 30 or October 4 to 6 line up with the rollout. A drop that started on September 15 has another cause.
- Rule out other causes. Check for a site migration, robots.txt or noindex changes, server errors, tracking issues and seasonal demand in the same period.
If the drop is sudden, sharp, matches the waves and is concentrated in one type of content, the spam update is the likely cause.
Which Spam Policies to Review
Google has not said what this update targeted. Its documentation simply says affected sites should review its spam policies. These are the ones I check first on any site that dropped:
- Scaled content abuse. Hundreds of pages produced mainly to rank, with little original value, whether written by AI, freelancers or templates. City pages that only swap the location name are a classic example.
- Site reputation abuse. Third party content hosted on a strong domain to borrow its authority, such as coupon, casino or product review sections that have nothing to do with the main site.
- Expired domain abuse. Buying an old domain and filling it with unrelated content to ride its past reputation.
- Thin affiliate pages. Product pages copied from merchant feeds with no testing, comparison or original insight.
- Doorway pages. Many near identical pages that all funnel visitors to the same destination.
- Fake authorship. Invented author names, stock photo bios and credentials that do not exist.
- Keyword stuffing and hidden text. Old tricks that still get caught.
Be honest when you review. If a page exists only because a keyword tool said so, and a real visitor would not miss it, it is a risk.
How to Recover From the Google September 2026 Spam Update
Recovery from a spam update is not a quick switch. Google’s systems need to recrawl your site and see that it changed, which often takes months. Here is the order I follow with clients:
- Export the affected pages from Search Console into a sheet. Add columns for clicks before, clicks after, word count, and whether the page has original value.
- Sort pages into three groups: keep and improve, merge into a stronger page, or remove.
- Improve the pages worth keeping. Add first hand experience, real examples, original images, data you collected yourself and a clear answer to the searcher’s question.
- Merge thin overlapping pages. Combine five weak posts on the same topic into one strong guide and 301 redirect the old URLs to it.
- Remove what cannot be saved. Return a 410 or 404 for pages with no value and no traffic. Use noindex for pages users still need but search does not.
- Fix authorship. Use real authors with real bios, photos and links to their profiles.
- Track weekly, judge quarterly. Request indexing for key improved pages, update your XML sitemap, and watch impressions. Real recovery usually becomes visible after the next spam or core update.
Mistakes That Make It Worse
- Deleting pages in bulk on day one. You may remove pages that were never the problem and lose links and rankings you still had.
- Blaming the Google September 2026 spam update for every dip. Check dates first. A drop that started before September 24 has another cause.
- Disavowing links in a panic. This was not a link spam update. A random disavow file rarely helps and can hurt.
- Changing everything at once. If you rewrite titles, redesign the site and move URLs together, you will never know what worked.
- Replacing thin AI content with more thin AI content. Rewording a weak page does not add value. Experience, data and real examples do.
- Filing a reconsideration request. That only applies to manual actions. For an algorithmic drop, there is nothing to submit.
- Giving up after four weeks. Spam related recoveries are slow. Keep improving and keep measuring.
Why This Matters for AI Search Too
Google’s AI Overviews and AI Mode draw on the same index and the same quality systems as regular search. If your pages were demoted by the Google September 2026 spam update, they are far less likely to be cited in AI answers either.
Other AI engines such as ChatGPT and Perplexity also lean on pages that already rank well and look trustworthy. So the fix is the same for both worlds: fewer, stronger pages with real expertise, clear answers and honest authorship. Cleaning up after a spam update is also your first step in Generative Engine Optimization.
Frequently Asked Questions

It started on September 24, 2026 and finished on October 8, 2026.
Did the Google September 2026 spam update target backlinks?
No. It was not a link spam update, and Google did not name a specific spam type.
Will Google notify me if my site was hit?
No. Spam updates are algorithmic. Only manual actions appear in Search Console with a message.

Google has not announced one. A spam update does not reliably predict a core update.
Final Word
The Google September 2026 spam update is not a reason to panic. It is a reason to audit. Confirm the dates, find the pages that actually lost visibility, review them honestly against Google’s spam policies, and improve or remove what does not serve your visitors.
If you are not sure whether your drop came from this update, send me a message with your site and the dates you saw the change. I will tell you what I see.
