Google has released its September 2026 Spam Update, and unlike a core update, this release is specifically identified by Google as an improvement to its spam-detection systems. Google says the update began on September 24, 2026, applies globally and to all languages, and may take up to two weeks to complete.
There is one detail that matters more than most headlines: Google has not publicly identified a specific spam tactic or content category as the target of this update. That means SEOs should resist turning early ranking movement into a list of “confirmed targets.” The useful response is to understand what Google officially considers spam today, compare that with what happened to your own pages, and remove practices that create genuine Search quality risk.
This article separates Google-confirmed information from industry observations. The September 2026 Spam Update was still listed as active on Google’s Search Status Dashboard when this article was prepared. The safest way to evaluate impact is therefore to keep monitoring while avoiding large, reactive site-wide changes based only on day-to-day volatility.
Google September 2026 Spam Update: What Has Actually Been Confirmed?
The official announcement is intentionally brief. Google identifies this release as a spam update, not a core update, and its Search Status Dashboard provides the core facts site owners need to know.

Why the Lack of a Named Target Matters
Google’s spam systems operate continuously, and Google describes notable improvements to those systems as spam updates. Its guidance says that sites affected by a spam update should review the spam policies to make sure their pages comply. This is different from treating every ranking decline as proof that one specific tactic was detected.
That distinction is important during an active rollout. A ranking movement observed on September 25, 26, or 27 can be a useful signal to investigate, but it is not by itself evidence that Google has declared a particular practice to be the cause.
Google’s own spam-update documentation also notes that improvements made after an issue is identified may take time to be reflected in Search, because automated systems may need to learn that a site is compliant over a period of time.
September 2026 Spam Update Timeline
Observed volatility is not the same as an official ranking explanation. Search Engine Roundtable reported strong movement over the opening weekend, while Semrush noted that Google has not disclosed what the update targets and that the rollout may take longer than some previous updates. Those are observations about the rollout, not a confirmed list of affected tactics.
What the September Spam Update Does Not Mean
Because spam updates often arrive alongside AI-related Search changes, it is easy to overread the announcement. A few conclusions are not supported by Google’s published information.
✓It is not an AI-content ban. Google says the way content is produced is not the deciding issue. AI-assisted or AI-generated content can be acceptable when it is useful, original, accurate, and created in line with Search policies.
✓It is not a core update. Google explicitly lists this release as a spam update, so it should be analyzed through the spam-policy lens rather than treating every content-quality movement as evidence of a broad core-system change.
✓It does not mean every traffic drop is update-related. Seasonality, competitors, indexing changes, technical issues, SERP features, demand shifts, and unrelated ranking changes can occur at the same time.
✓It does not create a new magic optimization. Google continues to emphasize Search Essentials, helpful content, strong technical foundations, and compliance with spam policies.
Where to Audit Your Website Right Now
Since Google has not named a specific target, the most defensible strategy is to audit the practices that Google currently classifies as spam. This is also the approach recommended in Google’s guidance for sites that see changes after spam updates.
1. Scaled Content Abuse
Google defines scaled content abuse as producing many pages primarily to manipulate rankings rather than to help users. Its examples explicitly include using generative AI or other tools to create many pages without adding value, scraping feeds or search results into pages with little value, stitching together material from multiple sources, and creating pages that contain keywords but provide little useful information.
Look at groups of similar pages. Ask whether each page has a real audience, a distinct purpose, original information, and enough value to deserve its own URL. If a page exists mainly because a keyword exists, that is a stronger risk signal than the mere fact that automation was used.
2. Scraped, Rewritten, or Thinly Repurposed Content
Google’s spam policy also addresses scraping and republishing content with little or no added value. Slightly rewriting another article, translating it automatically, stitching multiple sources together, or reproducing a feed without creating a meaningful benefit for the reader can create risk when the primary purpose is ranking manipulation.
A useful editorial benchmark is simple: could a reader learn something from your page that they would not get by reading the sources you used? Add original examples, first-hand observations, actual data, practical workflows, expert commentary, or a clearly differentiated analysis rather than changing words sentence by sentence.
3. Keyword Stuffing
Google defines keyword stuffing as filling a page with keywords or numbers in an attempt to manipulate rankings. That includes unnatural repetition, keyword blocks, and repetitive geographic or commercial terms that make the page harder to read.

Natural terminology |
RISKY
Repeating the same exact phrase unnaturally |
4. Link Spam and Artificial Authority
Google’s current link-spam policy covers buying or selling links for ranking purposes, excessive link exchanges, automated link creation, paid articles that pass ranking credit, optimized links in certain guest posts or press releases, low-quality directory links, and other link patterns created primarily to manipulate Search.
For an SEO team, the audit should include both newly acquired links and older campaigns. Look for repeated commercial anchors, scaled placements, networks of low-quality sites, large numbers of nearly identical referring pages, and links whose primary purpose appears to be passing ranking credit rather than helping a reader discover a useful resource.
Do not assume that a high domain authority score from a third-party tool makes a link safe. Google explicitly advises site owners to evaluate third-party SEO advice against its own Search guidance, and no external tool has access to Google’s internal ranking systems.
5. Site Reputation Abuse
Google’s site reputation policy covers third-party content published on an established host mainly because the host already has strong ranking signals. Importantly, Google says that third-party content by itself is not a violation. The issue is the purpose of placing that content on the host domain and whether it is being used to exploit the host’s established ranking signals.
Google’s August 28, 2026 policy update also changed how this policy is enforced for users in the European Economic Area. That policy change should be treated as a separate Search-policy development, not as proof that the September spam update is aimed at site reputation abuse.
6. Cloaking, Hidden Text, Doorway Pages, and Deceptive UX
Spam audits should not stop at content and backlinks. Google’s policies also cover cloaking, doorway abuse, hidden text and link abuse, misleading functionality, hacked content, sneaky redirects, and other deceptive techniques.
Check important landing pages from both the Googlebot perspective and a normal user perspective. Review dynamically injected text, redirect logic, hidden elements, location pages, template-generated URLs, JavaScript-driven content, and any changes that could cause search engines and users to receive meaningfully different experiences.
AI Content After the September Spam Update: What Google Actually Says
AI is likely to be part of the September conversation because Google has been strengthening its anti-spam systems while also expanding generative AI experiences in Search. But the safest interpretation is not “Google is detecting AI-written text and automatically penalizing it.”
Google’s published guidance says the problem is not AI assistance itself. The problem is using automation, including generative AI, to create large amounts of low-value content primarily to manipulate Search rankings. Google also recommends focusing on accuracy, quality, relevance, originality, and the needs of the audience.
✓Was there a real audience need for the page before the keyword was selected?
✓Does the page contain original reporting, examples, analysis, data, or experience?
✓Did an expert or knowledgeable editor verify factual claims?
✓Does the page answer the query completely instead of simply summarizing existing SERP content?
✓Would the article still be worth publishing if Google Search did not exist?
For current Google guidance, see Google’s guidance on generative AI content and Google’s guide to optimizing for generative AI features.
AI Search Spam Is Part of the Same Policy Framework
Google’s spam documentation now explicitly says that Search spam includes attempts to manipulate generative AI responses in Google Search. That means the same broader anti-manipulation principle applies beyond classic blue-link rankings.
Google’s AI-search guidance also warns against tactics such as seeking inauthentic mentions across the web simply to influence AI visibility. There is no special shortcut in which artificial mentions, forced keyword patterns, or an “AI-only” content layer guarantees inclusion in AI Overviews or AI Mode.
Build genuine authority and useful content first. Do not treat AI citations as a separate loophole around Google’s Search spam policies. Google says its standard Search best practices remain the foundation for generative AI features.
What About Google’s New SAFE System?
One notable development arrived immediately after the spam update began. Google Research published a paper describing SAFE, the Scaled Abuse Forensics Examiner, an automated multi-agent architecture designed to investigate coordinated synthetic media abuse. The system analyzes relationships between channels, behavior patterns, and content signals to identify policy violations and behavior that resembles “AI slop” campaigns.
This is interesting context for the wider anti-abuse direction, but it is important not to overstate the connection. Google Research’s publication does not say that SAFE powers the September 2026 Google Search Spam Update. The September Search Status Dashboard also does not identify SAFE as the update’s mechanism.
The broader lesson is that automated abuse detection is becoming more sophisticated. Site owners should not build a strategy around trying to “look less AI” or evade detectors. Build pages that are genuinely useful, original, accurate, and clearly accountable to a real publisher instead.
How to Diagnose a Ranking Drop During the Rollout
Do not start by editing hundreds of pages. Start by separating correlation from causation.
| CHECK | WHAT TO LOOK FOR | WHY IT MATTERS |
|---|---|---|
| Date alignment | Compare traffic and rankings before and after September 24. | Establishes whether the timing is compatible with the rollout. |
| Page clusters | Look for patterns across templates, folders, topics, or content types. | Cluster-level changes are more informative than one isolated URL. |
| Query intent | Compare commercial, informational, branded, and long-tail queries. | Shows whether a change is concentrated in a particular search intent. |
| Manual Actions | Check Search Console for any new manual action. | A manual action is different from an algorithmic ranking change. |
| Technical health | Review indexing, robots, canonicals, server errors, rendering, and internal links. | A technical issue can look like an algorithmic problem. |
Use Search Console as Your Primary Evidence
Export page and query data around the update period, then compare the affected pages with pages that remained stable. Look at clicks, impressions, average position, device, country, query class, and landing-page patterns. For sites with enough AI-search traffic, Google’s generative AI performance reporting can also help you understand how content is being surfaced in AI features.
Keep the before-and-after dataset. It becomes much more useful when the rollout is complete and you can distinguish sustained movement from temporary volatility.
September 2026 Spam Update Action Plan
✓Record a clean baseline for traffic, impressions, clicks, rankings, conversions, and top landing pages.
✓Check Search Console for manual actions, indexing anomalies, and technical errors.
✓Audit high-volume content clusters for scaled, repetitive, scraped, or thin pages.
✓Review link acquisition patterns and remove or qualify clearly manipulative placements as appropriate.
✓Review third-party sections, affiliate areas, and sponsored content for clear ownership, editorial responsibility, and genuine integration with the site.
✓Verify that key pages do not use cloaking, hidden text, doorway patterns, deceptive redirects, or misleading functionality.
✓Keep changes documented so you can compare the site state with performance after the rollout finishes.
Then Move From Cleanup to Improvement
Once the audit identifies a genuine weakness, improve the page itself rather than editing it around an imagined algorithm signal. Replace generic summaries with original analysis. Add real examples. Strengthen authorship and editorial accountability where appropriate. Consolidate pages that do not deserve separate URLs. Improve internal linking and site navigation. Make important content easy for users and crawlers to find.
This aligns with Google’s broader people-first guidance, which asks creators to consider whether their content is original, substantial, helpful, reliable, well-produced, and created for a real audience rather than primarily for search traffic.
The Bigger SEO Shift Behind This Update
The most useful takeaway from the September update is not a new checklist of tricks. It is the continued movement toward systems that evaluate whether content and links are genuinely useful or are being produced to manipulate visibility.

Google’s current guidance for generative AI Search points in the same direction: create valuable, non-commodity content; keep your technical structure clear; avoid manipulative AI-search shortcuts; and continue applying fundamental SEO best practices.
What SEO Teams Should Watch Next
1. Rollout completion. Do not treat September 30 as the end of the process simply because a week has passed. Google says the rollout may take up to two weeks.
2. Persistent page clusters. If the same type of content remains down after the rollout, investigate the underlying content or policy issue rather than reacting to individual keyword changes.
3. Official documentation changes. Google sometimes clarifies policies or publishes additional information after systems have started rolling out.
4. Your own evidence. Keep your GSC and analytics exports. Your first-party data will be more actionable than generalized “winners and losers” lists.

Frequently Asked Questions
What is the Google September 2026 Spam Update?
It is a Google Search spam update released on September 24, 2026. Google says it applies globally and to all languages and may take up to two weeks to complete. It is classified as a spam update rather than a core update.
What does the September 2026 Google Spam Update target?
Google has not publicly identified a specific spam tactic or industry as the target. The most reliable approach is therefore to review Google’s current spam policies and compare them with any sustained changes in your own site data.
Is the September 2026 update related to AI-generated content?
Google has not said that AI-generated content by itself is the target. Google’s published guidance says AI or automation can be used appropriately, but using it to create large amounts of low-value content primarily to manipulate rankings can violate the scaled content abuse policy.
Should I stop publishing new content during the update?
There is no Google instruction saying sites should stop publishing during a spam update. Continue publishing content that has a clear audience need, is original and useful, and follows Search policies. Avoid publishing large batches of thin or repetitive pages simply to capture keyword variations.
What should I do if my rankings dropped after September 24?
First confirm the timing and identify the page clusters that changed. Check Search Console, analytics, indexing, manual actions, content quality, links, and technical health. Because the rollout is still active, avoid making broad site-wide changes based only on short-term volatility.
Does Google penalize every website that uses AI?
No. Google’s guidance says the focus is on content quality and intent rather than whether AI was used. The risk arises when automation is used to generate content primarily for manipulating Search rankings, especially when pages add little or no value.
What is Google’s SAFE system?
SAFE stands for Scaled Abuse Forensics Examiner. Google Research describes it as a multi-agent system for investigating coordinated synthetic media abuse. The publication does not state that SAFE powers the September 2026 Search spam update, so the two should not be treated as the same announcement.
How long will the September 2026 Spam Update take?
Google says the rollout may take up to two weeks. Industry analysis has suggested it may take longer than some recent spam updates, so the status dashboard should be treated as the primary source for completion.
