Google has released its September 2026 Spam Update.
The update began rolling out on September 24, 2026, and applies globally across all languages and locations. Google says the rollout may take up to two weeks to complete.
Google also confirmed the release through its official LinkedIn post.
Website owners and SEOs may see ranking and traffic fluctuations while the rollout is underway.

What Is Google’s September 2026 Spam Update?
The September 2026 Spam Update is a Google Search ranking update focused on spam detection and enforcement of Google’s spam policies.
Google has not provided a detailed breakdown of the specific spam techniques targeted by this update. Its Search Status Dashboard currently lists the update as an incident affecting Ranking.
This means SEOs should avoid linking an individual ranking drop to a specific spam tactic until the rollout is complete.
September Spam Update Is the Fourth of 2026
The September rollout follows Google’s March, June, and August 2026 spam updates.
The September update is currently active, with Google giving the rollout a window of up to two weeks. That makes it important to separate temporary ranking volatility from sustained changes in organic performance.
What Could Change During the Spam Update?
Websites may experience changes in organic visibility while Google processes the update.
SEO teams could notice movement in:
- Organic rankings
- Search impressions
- Organic clicks
- Landing-page visibility
- Queries driving traffic
- Pages appearing in search results
Not every ranking change will be caused by the spam update. Normal search volatility and other Google ranking systems can also affect organic performance.
How Should SEOs Monitor the Update?
Google Search Console should be one of the main sources for monitoring performance during the rollout.
Compare clicks, impressions, average position, and landing-page performance with the period before September 24. Looking at several days of data can help distinguish sustained changes from short-term fluctuations.
If important pages lose visibility, review their content and site practices against Google’s spam policies before making major SEO changes.
Should You Change Your SEO Strategy?
There is no need to make large-scale SEO changes simply because Google has launched the update.
The better approach is to monitor performance while the rollout continues. If significant ranking or traffic losses remain after the update finishes, investigate the affected pages, queries, content patterns, and potential spam-policy issues.
This is also where separating organic search visibility from AI visibility becomes useful. A change in traditional organic rankings does not automatically tell you how a website is performing across AI search experiences.
The Bigger SEO Takeaway
Google’s September 2026 Spam Update is now rolling out globally, but its full impact will not be clear until the rollout is complete.
The key facts are straightforward: the update started September 24, applies to all languages and locations, and may take up to two weeks to finish.
For SEOs, the takeaway is simple: monitor the data, avoid rushed changes, and investigate sustained ranking shifts after the rollout settles.
