September 28, 2026 — Google has released its September 2026 Spam Update, marking another major spam-focused update to Google Search this year. The update began rolling out on September 24, 2026, and Google says the rollout may take up to two weeks to complete.
Unlike a broad core update, this update is specifically focused on Google’s systems for detecting and reducing search spam. The update is being rolled out globally and across all languages, meaning websites in India and other markets can be affected.
What Is the September 2026 Spam Update?
Google regularly improves its automated spam-detection systems to identify websites and content that violate its Search spam policies. These improvements can cause websites using manipulative or spam-related SEO practices to lose visibility in Google Search.
Google’s automated spam systems include SpamBrain, its AI-based system designed to detect and prevent different forms of search spam.
The September update represents another improvement to Google’s spam-detection systems and reinforces the importance of following Google’s Search Essentials and spam policies.

What Could Be Affected?
Google has not announced one specific spam technique that is exclusively targeted by this update. Therefore, SEO professionals should not assume that a single tactic is responsible for ranking changes.
However, websites should review practices such as:
- Automatically generated low-value content
- Large-scale content created primarily for search rankings
- Keyword stuffing
- Cloaking
- Sneaky redirects
- Hidden content
- Doorway pages
- Manipulative link practices
- Scraped or copied content
- Low-quality AI-generated content
- Content created primarily to manipulate search rankings
- Other practices that violate Google’s Search spam policies
Not every ranking decline during the update means that a website has received a spam action. Search rankings can change for many different reasons.
AI-Generated Content and Spam
The update is especially relevant as businesses continue to use generative AI to produce content at scale.
Using AI to assist with content creation does not automatically make content spam. The bigger concern is whether the content provides genuine value to users or is produced primarily to manipulate search rankings.
SEO teams should focus on:
AI assistance + human expertise + original information + useful experience + editorial review.
AI-generated content should be reviewed, fact-checked, edited and enhanced with original insights before publication.
What Should SEO Professionals Do?
If your website experiences a significant ranking or organic traffic decline during the September update, avoid making large-scale changes immediately.
1. Wait for the Rollout to Finish
Google says the update can take up to two weeks to complete.
Ranking fluctuations during the rollout may not represent the final impact.
2. Monitor Google Search Console
Compare your performance before and during the update.
Look at:
- Clicks
- Impressions
- Average position
- CTR
- Search queries
- Landing pages
- Countries
- Devices
3. Identify Affected Pages
Determine whether ranking losses are concentrated around:
- Specific content categories
- Blog posts
- Product pages
- Location pages
- Programmatic pages
- AI-generated content
- Particular website templates
This can help identify potential quality or spam-related patterns.
4. Audit Your Content
Review pages for:
- Thin content
- Duplicate content
- Outdated information
- Poor search intent alignment
- Excessive keyword usage
- Little original information
- Low-quality AI-generated content
Improve pages that fail to provide meaningful value.
5. Review AI-Generated Content
If your website uses AI extensively, check whether the content contains:
- Original insights
- Accurate information
- Human editing
- Industry expertise
- Real examples
- First-hand experience
- Helpful explanations
Avoid publishing large volumes of nearly identical AI-generated pages simply to target additional keywords.
6. Review Your Backlink Profile
Check your backlink profile for obvious signs of manipulation.
Look for:
- Paid links created solely for ranking
- Excessive exact-match anchor text
- Link networks
- Low-quality directory links
- Automated link-building patterns
- Large numbers of irrelevant backlinks
However, don’t assume that every backlink is harmful simply because it is low-quality.
7. Review Technical SEO
Check important technical elements such as:
- Robots.txt
- XML sitemap
- Canonical tags
- Redirects
- Indexation
- Internal links
- Structured data
- Mobile usability
- Page experience
Technical issues can sometimes appear alongside ranking changes and should be investigated separately from spam-related problems.
Why This Update Matters
The September 2026 Spam Update is important because Google’s spam systems are becoming increasingly sophisticated and automated.
Search engines are increasingly capable of identifying patterns rather than simply evaluating individual pages.
This means SEO strategies based heavily on:
automation + mass publishing + keyword manipulation + low-quality links
are becoming increasingly risky.
The long-term approach should instead focus on:
quality + relevance + originality + expertise + user value.
What If Your Website Loses Rankings?
If your website experiences a significant decline, don’t immediately delete hundreds of pages or completely change your SEO strategy.
First:
- Confirm that the decline began around the update.
- Compare rankings and traffic before and after September 24.
- Identify which pages and queries were affected.
- Review Google’s Search spam policies.
- Audit your content.
- Review your link-building practices.
- Check technical SEO issues.
- Improve genuinely weak pages.
- Continue monitoring performance after the rollout.
Recovery may not happen immediately. Google’s systems may need time to recrawl, process and reassess website changes.
Key Takeaway for SEO Professionals
The Google September 2026 Spam Update reinforces Google’s continuing effort to remove manipulative and low-quality content from search results.
SEO professionals should not focus solely on identifying the latest algorithm loophole. Instead, websites should build sustainable search visibility through:
- Helpful and original content
- Strong topical expertise
- Genuine user value
- High-quality technical SEO
- Natural internal linking
- Ethical link building
- Accurate information
- Strong user experience
- Appropriate use of AI
- Compliance with Google’s Search policies
The rollout is expected to continue for up to two weeks, so SEO teams should monitor their websites close
