Google has begun rolling out the September 2026 spam update, its fourth confirmed spam update of the year. It applies globally, covers every language, and unlike the earlier 2026 rollouts, Google says it may take up to two weeks to finish.
If your rankings or traffic have moved in the last few days, this update is one possible reason. Here is what is confirmed, what is not, and how to respond without overreacting.
What Google Has Confirmed
- Start time: The rollout began on September 24, 2026 at 09:15 PDT (16:15 UTC, or 9:45 PM in India).
- Scope: It applies globally and to all languages and locations.
- Duration: Google says the rollout may take up to two weeks. That is an upper estimate, so it could finish sooner.
- Type: Google described it as a normal spam update, which means no new spam policies were announced alongside it.
- Details: Google has not said which specific spam tactic or policy the update focuses on.
How It Compares With Earlier 2026 Spam Updates
| Update | Start date | Rollout length |
|---|---|---|
| March 2026 | March 24 | About 19.5 hours |
| June 2026 | June 24 | About 2 days |
| August 2026 | August 18 | About 2 days 16 hours |
| September 2026 | September 24 | Up to 2 weeks |
The longer window means ranking changes may appear gradually, and some SEO tracking tools had already shown volatility before the update was announced. Because several things can move rankings at once, do not assume every drop is caused by spam.
What a Spam Update Targets
Spam updates improve the automated systems Google uses to detect content that breaks its spam policies. Based on Google’s published policies, the usual areas include:
- Mass-produced, low-value content created mainly to capture search traffic, including auto-generated text that adds nothing new
- Keyword stuffing and thin pages
- Manipulative link schemes, such as paid or artificial links
- Cloaking, sneaky redirects and doorway pages
- Scraped content and abuse of expired domains or site reputation
Sites that follow Google’s guidelines are generally not the target. Even so, it is worth auditing yourself honestly, especially if you have scaled up content or link building recently.
How to Check Whether Your Site Was Affected
- Open Google Search Console and compare clicks, impressions and average position since September 24 against the 2 weeks before it.
- Look for patterns. A sitewide drop points to a different problem than a drop on a few pages or one section.
- Check for manual actions under Security & Manual Actions. Spam updates are algorithmic, but it is worth ruling out a penalty.
- Review recent changes: new bulk content, AI-generated pages, link campaigns, redirects or a site migration.
- Wait for the rollout to finish. Check the Google Search Status Dashboard for the completion notice before drawing conclusions.
What to Do If Your Rankings Dropped
- Do not panic-edit. Changes made mid-rollout make it hard to tell what caused what. Document the drop first, then act once the update completes.
- Audit your content. Remove or substantially improve thin, duplicated or purely auto-generated pages. Every page should serve a real reader need.
- Clean up your links. Stop buying links, and disavow only clearly toxic ones if you have a genuine pattern of them.
- Fix technical red flags such as hidden text, deceptive redirects and cloaked content.
- Be patient. Recovery from a spam-related drop usually shows up in a later update, not instantly after you fix things.
How to Stay Safe in Future Spam Updates
With four spam updates already this year, the safest strategy is a steady one. Publish original, genuinely useful content written for people. Build links by earning them, not buying them. Keep your site technically clean. Businesses doing local SEO should also keep their Google Business Profile accurate and free of keyword-stuffed names.
