Quick answer:
Google began rolling out the September 2026 spam update on 24 September with a window of up to two weeks, and a site that follows Google's spam policies should change nothing until the rollout is confirmed complete.Key Takeaways
- Google released the September 2026 spam update on 24 September 2026, and it applies globally and to all languages.
- Google says this rollout may take up to two weeks, while the March, June and August spam updates were each given a few days.
- Google calls this a normal spam update and has not said which spam policy or tactic it targets.
- The three earlier spam updates of 2026 took between 19.5 hours and 2 days 16 hours to finish.
- Rankings can move while a rollout is in progress, so compare Search Console data only after Google confirms the update is complete.
- A site hit by a spam update may improve after fixing the problem, but Google says its systems take months to recognise the fix.
Google released its September 2026 spam update on 24 September, shortly after 9am Pacific time. It is the fourth spam update this year, following March, June and August.
Google has given this rollout up to two weeks. Each of the three earlier spam updates this year was listed as taking a few days.
What Google announced
The entry on Google's Search Status Dashboard reads in full:
"Released the September 2026 spam update, which applies globally and to all languages. The rollout may take up to two weeks to complete."
In a LinkedIn post the same day, Google called it "a normal spam update" and named no target. Any claim this week about a specific target is speculation until Google publishes more detail.
Google's documentation on spam updates says its automated spam detection systems, such as SpamBrain, run all the time. Google announces a spam update when it makes a notable improvement to how those systems work.
How it compares with this year's other spam updates
Google has not explained why the September window is longer. "Up to two weeks" is an upper limit, so the rollout may finish before 8 October.
| Spam update | Start date (Pacific time) | Window Google announced | Time the rollout took |
|---|---|---|---|
| March 2026 | 24 March | A few days | 19 hours 30 minutes |
| June 2026 | 24 June | A few days | 2 days 1 hour |
| August 2026 | 18 August | A few days | 2 days 16 hours |
| September 2026 | 24 September | Up to two weeks | Still rolling out |
What Google's spam policies cover
Spam updates enforce Google's spam policies, which list the practices that can push a site lower in results or remove it altogether. The list includes these practices:
- Scaled content abuse. Publishing many pages mainly to manipulate rankings, however those pages were produced.
- Link spam. Buying or selling links, or exchanging them excessively, mainly to manipulate rankings.
- Doorway abuse. Creating near duplicate pages that target similar searches and funnel visitors to another page.
- Keyword stuffing. Filling a page with keywords or numbers to manipulate rankings, often in unnatural lists.
- Hacked content. Pages, links or code placed on a site without the owner's permission.
Hacked content deserves a closer look because the site owner never created it. If an attacker adds spam pages or links to your site, Google can treat them as spam and a security problem becomes a ranking problem.
After the August update, the reports that followed focused on sites publishing AI content at scale, which we covered in what the August update hit. Google has not said whether the September update continues that focus.
What to do while the update rolls out
Three steps stop you from reacting to rankings that are still moving:
1. Record your baseline now
Open the Performance report in Google Search Console and export clicks and impressions by page for the four weeks ending 23 September. That period sits entirely before the rollout, so it gives you a clean point of comparison.
2. Leave your pages alone until it finishes
Rankings can rise, fall and partly recover while a rollout is in progress, so a drop on day two may not be where you end up. If you rewrite or delete pages mid-rollout, you will not be able to tell whether the update or your edit caused the next change.
3. Compare matching periods once it ends
When the dashboard marks the rollout complete, compare the seven days after the end date with the seven days before 24 September. Check whether any drop lines up with the rollout dates and whether it affects the whole site or a small group of pages.
Also open the Manual actions report in Search Console. A manual action is a penalty applied by a human reviewer, and it comes with its own notice and fix process.
Reading your results after the rollout
When a drop started and how far it spreads point to its likely cause. Search Engine Roundtable reported heavy movement in rank tracking tools from around 23 September, before Google announced the update.
| What you see | What it usually means | What to do next |
|---|---|---|
| Traffic steady or higher | The update did not affect your site | Nothing |
| A drop that began before 24 September | Something else, such as an unconfirmed ranking change, a site change, a tracking fault or seasonal demand | Check recent releases, analytics and indexing |
| A drop on a few pages inside the rollout window | Those pages may break a spam policy | Review them against the policy list above |
| A drop across the whole site inside the window | The site as a whole may be flagged | Audit content, links and site security |
| A notice in the Manual actions report | A human reviewer applied a penalty | Fix the issue, then request reconsideration |
If the update hits your site
Google's advice for sites that lose visibility after a spam update is to review the spam policies and fix anything that breaks them. The same documentation is direct about how long recovery takes:
"Making changes may help a site improve if our automated systems learn over a period of months that the site complies with our spam policies."
A fix made this week is unlikely to show up in next week's numbers.
Link spam updates work differently. When Google's systems discount spammy links, Google says the ranking benefit those links gave is lost and cannot be regained.
That warning applies to link spam updates. Google called this one a normal spam update, so fixing problems may still help your site improve over time.
Recovery means auditing content, links and site security, then keeping the site clean for months. If nobody in your business has time for that, our comparison of a freelancer, agency or in-house hire shows who suits the workload.
