Google has started rolling out the Google September 2026 Spam Update, bringing another confirmed change to how Google Search identifies and handles spam. The rollout began on September 24, 2026, and applies globally across all languages. Google has also stated that the rollout may take up to two weeks to complete.
For businesses, website owners, and SEO professionals, this means some ranking and traffic fluctuations may occur while Google’s systems process the update. However, not every change in organic performance during this period should automatically be attributed to the spam update.
What Is the Google September 2026 Spam Update?
The Google September 2026 Spam Update is a Google Search update focused on improving the systems used to detect and handle search spam. Google regularly improves its automated spam detection systems to maintain the quality and relevance of Search results.
Google has not announced a detailed list of specific spam techniques targeted by this particular update. Therefore, website owners should avoid making assumptions about one particular SEO practice being affected. Instead, businesses should review their websites against Google’s existing spam policies and ensure their SEO activities follow search guidelines.
When Did the Google September 2026 Spam Update Start?
The Google September 2026 Spam Update began rolling out on September 24, 2026. The update is global and applies to all languages. According to Google’s announcement, the rollout may take up to two weeks to complete.
This rollout period is important for website owners because ranking movements during the next several days may not represent the final impact of the update. Businesses should monitor their organic performance throughout the rollout instead of making major SEO decisions based only on short-term fluctuations.
How Is the Google September 2026 Spam Update Different From a Core Update?
A spam update and a core update have different purposes.
The Google September 2026 Spam Update focuses on Google’s systems for identifying websites and practices that violate its spam policies. Core updates involve broader changes to Google’s ranking systems and can affect how content is evaluated across Search.
Google’s spam policies cover practices such as cloaking, keyword stuffing, link spam, scaled content abuse, scraping, sneaky redirects, expired domain abuse, hacked content, and other techniques designed to manipulate Search rankings.
Understanding this difference is important because a ranking change during a spam update does not necessarily indicate the same type of impact associated with a core update.
What Could the Google September 2026 Spam Update Mean for Websites?
The impact of the Google September 2026 Spam Update can vary from one website to another. During a spam update, some websites may experience changes in rankings, impressions, clicks, or organic traffic.
A sudden decline in traffic does not automatically mean that a website has received a spam-related action. Rankings can change for several reasons, and the September 2026 rollout is still in progress.
Website owners should compare their Google Search Console data before and after the update and identify whether changes are occurring across the entire website or only on specific pages and search queries.
Content Quality Remains Important After the Google September 2026 Spam Update
One area businesses should pay particular attention to is content quality.
Google identifies scaled content abuse as creating large amounts of content primarily to manipulate search rankings rather than provide value to users. This can include unoriginal content, automatically generated pages without meaningful added value, scraped information, or pages created mainly around search keywords.
The Google September 2026 Spam Update does not mean that using AI as part of content creation is automatically considered spam. The quality and usefulness of the final content remain important. Businesses should ensure that their content provides original insights, accurate information, clear answers, and genuine value to visitors.
For businesses publishing blogs, service pages, location pages, or product content, the focus should remain on useful information, originality, accuracy, and a positive user experience.
What Should Businesses Check During the Google September 2026 Spam Update?
While the Google September 2026 Spam Update continues to roll out, businesses can use this period to review their SEO practices and website health.
1. Review Existing Content
Check important pages for thin, repetitive, outdated, or low-value content. Every important page should have a clear purpose and provide useful information to visitors.
2. Avoid Keyword Stuffing
Using keywords naturally is different from repeatedly inserting the same keyword to manipulate rankings. Moreover, Google identifies keyword stuffing as a spam practice.
The focus should be on creating readable content where keywords fit naturally within the context of the page.
3. Review Link-Building Practices
Businesses should evaluate their backlink-building activities and ensure that they follow Google’s guidelines.
Manipulative link practices, including certain paid links, excessive link exchanges, automated link creation, and other attempts to influence rankings through unnatural links, can create SEO risks.
4. Check for Scraped or Duplicate Content
Content copied from other websites with little or no additional value can create quality concerns. Website owners should ensure that important pages provide original information and meaningful value to users.
5. Monitor Google Search Console
During the Google September 2026 Spam Update, regularly monitor Google Search Console for changes in clicks, impressions, average position, CTR, and page-level performance.
Comparing performance over time can help identify whether a change is temporary or continues after the rollout is complete.
What Should You Do If Rankings Drop After the Google September 2026 Spam Update?
Do not make rushed SEO changes simply because rankings fluctuate during the update.
First, check whether the change affects the entire website or only specific pages, keywords, or sections. Then review the affected pages against Google’s spam policies and examine any recent SEO changes.
If a website violates Google’s spam policies, it may experience reduced visibility in Search. After making improvements, website owners may need to allow Google’s systems time to reassess the website.
Businesses should therefore focus on identifying the actual cause of a decline instead of making large-scale changes based on temporary ranking movements.
How Can SEO Teams Prepare for Future Google Spam Updates?
The Google September 2026 Spam Update is another reminder that sustainable SEO requires consistent attention to website quality and search guidelines.
SEO teams should regularly review:
- Website content quality and originality
- Keyword usage and on-page optimisation
- Backlink profiles and link-building practices
- Technical SEO issues
- Duplicate or low-value pages
- User experience and website usability
- Google Search Console performance
- Compliance with Google’s Search spam policies
Regular monitoring can help businesses identify potential issues before they become larger SEO problems.
Conclusion
The Google September 2026 Spam Update began rolling out globally on September 24, 2026, and may take up to two weeks to complete. Since Google has not announced a specific spam tactic targeted by this update, businesses should avoid relying on speculation and instead focus on Google’s established Search spam policies.
For businesses, this is a useful opportunity to review website content, backlink practices, technical SEO, and overall optimisation processes. Sustainable SEO should focus on creating useful content, maintaining a trustworthy website, and following practices that provide genuine value to users.
As the Google September 2026 Spam Update continues to roll out, businesses and SEO teams should monitor Search Console, organic traffic, rankings, and affected pages before drawing conclusions about its long-term impact.
