TL;DR: Google rolled out a spam update on September 24, 2026, targeting link spam, keyword stuffing, cloaking, scraped content, and scaled low-value AI-generated content. Websites following Google's documented spam policies are unlikely to be affected. Those that experienced ranking drops should audit their content and link profiles against official Google guidance before making significant changes.
Google confirmed the rollout of a new spam update on September 24, 2026. The update targets content, websites, and link patterns that violate Google's spam policies. If your website traffic dropped around this date, or if you want to protect your rankings going forward, this guide explains exactly what happened and what it means for your website.
What Is the September 24 Google Spam Update?
The September 24 Google Spam Update is a confirmed algorithmic update that Google began rolling out on September 24, 2026. Google tracks active spam updates on its Search Status Dashboard, which provides the official start date, rollout status, and completion notice for each update.
Spam updates are different from core updates. A core update broadly reassesses how Google evaluates content quality across the entire web. A spam update specifically targets websites that violate Google's documented spam policies, including practices such as cloaking, keyword stuffing, link spam, auto-generated content with no real value, and scraped content published without meaningful transformation.
This update is part of Google's ongoing effort to reduce low-quality, manipulative, and deceptive content in search results, as described in how Google detects spam.
Why Did Google Release This Update?
Google releases spam updates periodically to enforce its quality standards and to ensure that search results remain useful, accurate, and trustworthy for users.
According to Google's spam updates documentation, the company runs both manual actions and algorithmic spam systems. Manual actions are applied by human reviewers to specific websites. Algorithmic spam updates affect rankings at scale without requiring individual review of each site.
The September 2026 update follows a pattern Google has maintained for several years, releasing multiple spam updates annually to stay ahead of tactics that violate its policies. Websites that rely on scaled content generation, purchased link networks, keyword-stuffed pages, or other manipulative practices are the primary targets.
What Does This Update Target?
Google's spam policies cover a specific set of practices. Understanding each one helps you identify whether your website could be affected.
Scaled content abuse refers to publishing large volumes of pages that provide little or no original value to users. This includes AI-generated content published without meaningful human review, editing, or factual verification. Google's position is that the production method itself is not the problem. The problem is content that exists to manipulate rankings rather than to inform readers.
Link spam refers to links that are created primarily to manipulate PageRank rather than to provide a genuine navigational resource for users. This includes paid links that are not properly disclosed, link exchanges for the purpose of ranking manipulation, and links generated through automated programmes.
Cloaking refers to showing different content to Google's crawlers than what is shown to human visitors. This practice is a direct violation of Google's guidelines because it prevents Google from accurately evaluating the true content of a page.
Keyword stuffing refers to loading a page with keywords at an unnatural density in an attempt to manipulate rankings. Google's systems are designed to detect unnatural keyword patterns, and pages that use this technique typically receive ranking penalties rather than ranking improvements.
Scraped content refers to copying content from other websites and republishing it with minimal or no transformation. Even with minor rewording, scraped content that does not add original analysis, explanation, or value is treated as a spam signal.
If your website does not use any of these practices, this update is unlikely to have affected your rankings. If your rankings dropped around September 24, 2026, reviewing your content and link profile against these criteria is the appropriate first step.
How Long Does a Google Spam Update Take to Roll Out?
Google spam updates typically take one to two weeks to complete rolling out globally. During this period, ranking fluctuations are normal. Some websites may see temporary drops that stabilise once the rollout is complete.
The official completion of the September 24 update will be confirmed on the Google Search Status Dashboard. Marketing professionals and SEO experts should monitor this dashboard directly rather than relying on third-party sources for confirmation of rollout status.
Waiting for the full rollout to complete before drawing conclusions about the impact on specific websites is advisable. Ranking changes observed in the first few days of any update may not reflect the final outcome.
What Should You Do If Your Website Was Affected?
If your website experienced a significant traffic or ranking drop around September 24, 2026, the following steps provide a structured approach to diagnosing the cause.
First, confirm the timing. Check your Google Search Console data to identify the date on which traffic or impressions dropped. If the drop aligns with September 24, 2026, the spam update is a likely cause. If the drop predates this update, another factor may be responsible.
Second, review your content against Google's spam policies. Go through your most important pages and ask whether each page provides genuine value to a real reader. If any pages were created primarily to target a keyword without providing useful information, those pages are candidates for improvement or removal.
Third, audit your link profile. Use a reputable link analysis tool to review the inbound links pointing to your website. Identify links from low-quality directories, link networks, or paid sources that were not disclosed. For links you did not create and cannot remove, Google's Disavow tool may be appropriate, though Google advises using it cautiously and only when there is clear evidence of harmful links.
Fourth, review your use of AI-generated content. If your website publishes content generated by AI tools, review whether that content was meaningfully edited, fact-checked, and improved before publication. Content that was published directly from an AI tool without human review is the type most likely to be affected by this update.
Fifth, avoid making large-scale changes while the rollout is still in progress. Waiting until the update has fully completed before making significant structural changes to your website is generally more effective than reacting to mid-rollout fluctuations.

Understanding how to create effective social media ads also helps diversify traffic sources so that organic search fluctuations have less impact on overall audience reach.
What Does This Mean for AI-Generated Content Specifically?
Google has been consistent in its guidance on AI-generated content. The content itself is not prohibited. Content that is low quality, unoriginal, and created primarily to manipulate rankings is what Google's systems are designed to penalise, regardless of how it was produced.
For marketing students and SEO professionals, this distinction is important. Using AI tools to assist with research, drafting, and organisation is a reasonable part of a content production workflow. Publishing large volumes of AI-generated pages without review, editing, or factual verification is the practice that creates spam risk.
The practical standard is this: if a page would be useful and accurate to a reader who arrived on it directly without any context about how it was created, the content is likely safe. If the page would appear thin, repetitive, or obviously assembled to target a keyword rather than to inform a reader, it is the type of content this update targets.

How Can You Protect Your Website from Future Spam Updates?
Protection against future Google spam updates comes from building a website on a foundation that Google's guidelines support rather than one that exploits gaps in algorithmic detection.
Publish content that answers real questions with accurate, original information. Build links by creating resources that other websites find worth citing, rather than through schemes designed to manufacture artificial authority. Use AI tools as assistants in your content workflow rather than as automated publishers. Review your most important pages regularly against Google's current spam policies, which are documented at developers.google.com/search/docs/essentials/spam-policies.
Websites that consistently follow these practices are generally not materially affected by spam updates because they are not doing the things those updates target.
