Google September 2026 Spam Update: What SEOs and Website Owners Need to Know

Google has started rolling out its September 2026 Spam Update, giving website owners and SEOs another reason to take a close look at how their sites are built, how content is produced, and whether their SEO tactics actually help users.

The update began on September 24, 2026, at 9:15 a.m. PDT. Google says the rollout applies globally and to all languages, and it may take up to two weeks to complete.

That last point matters. If your rankings suddenly move over the next several days, it is too early to assume that the September Spam Update is responsible. Search rankings can change for many reasons, and the rollout itself is still in progress.

So, what exactly has Google changed this time? And what should website owners actually do?

What Is the Google September 2026 Spam Update?

The September 2026 Spam Update is a confirmed Google Search ranking update focused on improving Google’s automated systems for detecting search spam.

Google’s official Search Status Dashboard lists the update as affecting ranking. The company has not announced a specific spam tactic or policy that this particular update is targeting.

This is important because it means SEOs should be careful with claims such as “Google is targeting AI content” or “Google is targeting backlinks” unless Google specifically confirms it.

At the moment, the official information is more limited: this is a global spam update, it applies to all languages, and the rollout may take up to two weeks.

Google’s Search Status Dashboard is the best place to check the official rollout status.

Is This a Core Update?

No. Google has identified this release as a spam update, not a core update.

That distinction is useful when diagnosing ranking changes.

A core update can involve broad changes to Google’s ranking systems and how it evaluates content relevance and quality. A spam update, on the other hand, focuses on improvements to Google’s systems for detecting and handling search spam.

Google explains that its automated spam-detection systems operate continuously, while notable improvements to those systems are sometimes announced as spam updates. Google specifically mentions SpamBrain, its AI-based spam-prevention system, as one part of its broader spam-fighting systems.

What Is Google Targeting?

This is where it is worth being careful.

As of September 25, 2026, Google has not publicly identified a specific spam tactic targeted by the September update. Google’s official announcement only says that the update applies globally and to all languages and that the rollout may take up to two weeks.

Therefore, it would be premature to say that the update specifically targets:

• AI-generated articles
• Backlinks
• Private Blog Networks (PBNs)
• Expired domains
• Parasite SEO
• Affiliate websites
• Programmatic SEO

Those techniques can have spam-policy implications depending on how they are used, but that is different from saying the September 2026 update specifically targets them.

For website owners, the more useful approach is to review Google’s existing spam policies rather than trying to guess which single tactic Google has changed.

Why Spam Updates Matter for Website Owners

Google’s spam policies exist to prevent techniques designed to manipulate Search or deceive users. Sites that violate those policies can rank lower or potentially disappear from Google Search results.

That means a spam update can matter even when a website owner never intentionally considered themselves a “spammer.”

For example, a site might gradually accumulate problems through:

• Large amounts of low-value content
• Automatically generated pages with little original value
• Scraped or lightly rewritten content
• Manipulative links
• Deceptive redirects or functionality
• Abusive user-generated content
• Other practices covered by Google’s spam policies

The important question is therefore not simply, “Did I get hit by the update?”

A better question is:

“Does my website still provide enough original value that people would find it useful even without Google traffic?”

Does the September 2026 Spam Update Target AI Content?

Not necessarily.

This is one of the easiest areas to misunderstand.

Google does not say that using generative AI automatically makes content spam. Its documentation explains that AI can be useful for researching topics and adding structure to original content. The problem occurs when automation is used to generate large amounts of content without adding value, particularly when the purpose is to manipulate Search rankings.

Google’s spam policy specifically describes scaled content abuse as creating many pages primarily to manipulate rankings rather than help users. The policy applies regardless of whether the content was produced by AI, humans, or a combination of both.

So there is an important distinction:

Approach	How to think about it
AI-assisted research and editing	Can be useful when the final content provides genuine value
AI-assisted drafting with human editorial work	Can be appropriate when accuracy, originality and usefulness are maintained
Mass-producing near-identical pages	Can create scaled content abuse concerns
Publishing AI-generated content solely to capture search traffic	Conflicts with Google’s people-first approach when ranking manipulation is the primary purpose

The technology used to create the article is therefore only part of the story. The purpose, quality, originality and value of the resulting content matter.

What About Backlinks?

Website owners who work heavily with link building should avoid jumping to conclusions about the September update.

Google has not announced that the September 2026 Spam Update is specifically a link spam update. In fact, Google’s documentation makes a distinction between general spam updates and updates specifically focused on link spam.

That does not mean links are irrelevant.

Google’s spam policies cover manipulative practices, and link-related tactics can create problems when their purpose is to manipulate Search rankings rather than provide legitimate value.

For SEO practitioners, this is a good reminder to look beyond metrics such as Domain Authority, traffic estimates or the raw number of backlinks.

A backlink strategy should also consider:

• Topical relevance
• Editorial context
• The quality of the referring website
• Whether the link provides value to users
• The overall pattern of link acquisition
• Whether the strategy depends on manipulating Google’s systems

A large backlink profile does not automatically mean a website has a strong or sustainable SEO strategy.

Could Expired Domains Be Affected?

Expired domain abuse is already part of Google’s spam-policy framework.

Google describes expired domain abuse as repurposing an expired domain primarily to manipulate Search rankings using the reputation of the old domain, particularly when the new content provides little value to users.

That does not mean every website built on an expired domain violates Google’s policies.

Using an old domain for a legitimate new website is not inherently abusive. The key issue is how the domain is being used and whether the resulting site is created primarily to manipulate Search.

What About Scaled Content and Programmatic SEO?

This is an area worth reviewing carefully, particularly for publishers operating hundreds or thousands of pages.

Google defines scaled content abuse as producing many pages primarily to manipulate Search rankings rather than help users. The policy explicitly says this can involve AI-generated pages, scraped material, automatically transformed content, stitched-together content and other forms of mass-produced low-value pages.

Programmatic SEO itself is not automatically spam.

A website can legitimately generate large numbers of useful pages when each page serves a genuine user need and contains meaningful information.

The problem starts when the system becomes:

keyword → automatically generated page → little original information → publish thousands of variations.

That is very different from building a useful database, directory, comparison tool or information resource where the underlying data and functionality genuinely help users.

What Should You Do If Your Rankings Drop?

First, don’t panic.

The September update is still rolling out, and Google says the process may take up to two weeks. A ranking change observed today may not represent the final effect of the update.

Start by checking Google Search Console and compare your performance with the period before September 24.

1. Check Whether the Timing Matches

Look at impressions, clicks, average position and affected queries.

If the decline began long before September 24, the September spam update may not be the explanation.

Similarly, if only one article dropped while the rest of the site remained stable, it may be more useful to investigate that page specifically instead of assuming the entire domain was penalized.

2. Review Google’s Spam Policies

Google recommends that sites experiencing changes after spam updates review its spam policies and make sure the site complies with them.

Pay particular attention to areas such as:

• Scaled content abuse
• Scraping
• Manipulative link practices
• Thin affiliate content
• Deceptive functionality
• User-generated spam
• Expired domain abuse
• Site reputation abuse

These policies are broader than simply checking whether an article contains keywords.

3. Audit Your Lowest-Value Pages

Look at pages that receive little traffic, provide almost no original information, or exist mainly because a keyword appeared in a content plan.

Ask yourself:

• Does this page answer a real question?
• Does it provide information that is actually useful?
• Is the information original or simply rewritten from other websites?
• Would someone bookmark or share the page if Google disappeared tomorrow?
• Does the page have a clear reason to exist?

If the answer is consistently no, the problem may be deeper than the page’s keyword optimization.

4. Review Your Content Production Process

This is especially important for websites publishing content at scale.

Don’t only ask whether AI was used. Ask how the content was produced.

A workflow such as research → original analysis → expert review → fact checking → editing → publication is fundamentally different from automatically generating thousands of pages and publishing them without meaningful editorial review.

Google’s guidance emphasizes the purpose behind content creation: content should primarily exist to help people, rather than primarily to attract search-engine visits.

Should You Stop Publishing During the Update?

There is no official Google guidance saying that websites should stop publishing content during a spam update.

If your editorial process produces useful, original and accurate content, there is no obvious reason to stop simply because an update is rolling out.

What may be worth reconsidering is publishing content purely because you want to increase the number of indexed URLs.

More URLs do not automatically mean more SEO value.

For many publishers, improving existing articles can be more useful than continuously adding pages that overlap with content already on the site.

How Long Will the September 2026 Spam Update Take?

Google says the rollout may take up to two weeks.

This is noticeably longer than several earlier spam updates in 2026. Google’s ranking history shows the March 2026 spam update lasted about 19 hours, the June update about two days, and the August update about two days and 16 hours.

That does not mean the September update will definitely take the full two weeks. It simply means website owners should give Google time to complete the rollout before making major conclusions about its impact.

What If Your Site Recovers Later?

Google’s documentation says that making improvements may help a site if its automated systems later determine that the site complies with spam policies. However, Google also notes that recovery can take time because its systems may need to reassess a site over a period of months.

In other words, fixing a problem does not necessarily mean rankings will bounce back the next morning.

That is another reason to avoid making dozens of random changes immediately after seeing a ranking decline.

A Practical September 2026 Spam Update Checklist

Area	What to check
Search Console	Compare clicks, impressions, queries and rankings before and after September 24
Content	Look for thin, repetitive or low-value pages
AI content	Check whether AI-assisted pages contain meaningful original value and editorial review
Links	Review unusual or manipulative link-building patterns
Expired domains	Check whether old domains are being used for legitimate purposes rather than ranking manipulation
User-generated content	Look for spammy comments, profiles, posts or uploaded files
Site functionality	Check for deceptive redirects, misleading buttons or malicious behavior
Editorial process	Make sure content is created primarily for users rather than search-engine manipulation

The Bigger SEO Lesson From the September 2026 Update

The most useful takeaway is not to chase rumors about what Google may or may not be targeting.

Google’s official announcement gives us relatively little detail about the specific mechanisms changed in this release. What we do know is that the update is a global spam update, and Google’s existing spam policies provide the framework for understanding what kinds of practices can create problems.

For website owners, that makes the fundamentals more important:

• Create content for people first.
• Add original information and useful context.
• Don’t publish pages simply to capture keywords.
• Use AI as a tool rather than a substitute for editorial judgment.
• Avoid manipulative SEO tactics.
• Keep your website useful even without search traffic.
• Verify important factual claims.
• Monitor Search Console rather than relying on SEO rumors.

Google’s Search Essentials similarly recommends creating helpful, reliable, people-first content and warns that spam-policy violations can result in lower rankings or removal from Search.

Final Takeaway

The Google September 2026 Spam Update is now rolling out globally, but there is still limited official information about the specific changes behind it.

That makes this a poor time to react to every ranking fluctuation or SEO rumor.

Instead, use the rollout as an opportunity to audit the fundamentals: content quality, originality, user value, link practices, scalable publishing systems and overall compliance with Google’s spam policies.

The goal should not simply be to survive one Google update. A stronger approach is to build a website that remains useful to readers even when Google’s algorithms change.
