Google launched the September 2026 spam update on September 24, 2026. The update applies globally, affects all languages, and may take up to two weeks to fully roll out. As of September 29, Google still lists the update as active. It is the fourth confirmed spam update of 2026 following updates in March, June, and August.
Search ranking volatility became particularly noticeable between September 25 and September 27, but Google has not said which specific spam tactic or policy this update is targeting. That makes it too early to look at a few days of ranking movement and confidently decide what changed.
What is the September 2026 Google spam update?
The September 2026 spam update is a Google Search ranking update intended to improve Google’s automated systems for identifying websites and content that violate its spam policies.
Google’s spam-detection systems operate continuously. When Google makes a notable improvement to how those systems identify search spam, it may announce the change as a spam update.
One of those systems is SpamBrain, Google’s AI-based spam-prevention system. Google periodically improves SpamBrain and other automated systems so they can identify new or evolving forms of spam.
Google has not announced a new spam policy specifically for the September rollout.
September 2026 spam update quick facts
| Detail | September 2026 spam update |
|---|---|
| Launch date | September 24, 2026 |
| Start time | 9:15 a.m. PDT |
| Status | Still rolling out as of September 29 |
| Expected rollout | Up to two weeks |
| Coverage | Global |
| Languages | All languages |
| Update type | Spam update |
| Specific target disclosed? | No |
| Fourth spam update of 2026? | Yes |
Google has confirmed the timing, scope, and rollout window, but has not disclosed which specific spam systems or policies were changed.
When did the September 2026 spam update start?
The September 2026 spam update began on September 24, 2026 at 9:15 a.m. PDT, according to Google’s Search Status Dashboard.
Google said the rollout may take up to two weeks.
That could put completion sometime in early October, but “up to two weeks” is an estimated rollout window, not a confirmed completion date.
Google could finish sooner.
The update should not be considered complete until Google updates its official ranking release status.
Is the September 2026 spam update finished?
No, not as of September 29, 2026.
Google still lists the September spam update as rolling out.
That matters because rankings can continue changing while an update is being deployed.
A page that loses visibility during the first few days could recover later in the rollout. A page that suddenly gains rankings could also move again before the update settles.
This is why comparing September 25 to September 26 and immediately rewriting half of a website is usually not productive.
Short-term movement during an active rollout should be monitored, not automatically treated as the final outcome.
What is the September 2026 spam update targeting?
Google has not said which specific spam tactic or policy the September update is targeting.
That distinction is important because Google’s spam policies cover many different types of behavior.
Examples include:
- Cloaking
- Doorway abuse
- Expired domain abuse
- Hidden text and links
- Keyword stuffing
- Link spam
- Scaled content abuse
- Scraped content
- Site reputation abuse
- Other attempts to manipulate search rankings
A site declining during the September update does not automatically mean one of these specific practices caused the drop.
Google has not provided enough information to make that conclusion yet.
Does this update specifically target AI content?
Google has not said the September 2026 spam update specifically targets AI-generated content.
Using AI is not automatically a violation of Google’s spam policies.
The more important issue is why and how the content was created.
Google defines scaled content abuse around producing large amounts of content primarily to manipulate rankings rather than help users. That can apply whether the content was created by AI, automation, humans, or a combination of methods.
A useful article that happens to use AI during research or drafting is different from publishing thousands of low-value pages because software makes it inexpensive to do so.
The problem is not simply the tool.
The problem is producing content primarily for ranking manipulation without meaningful value.
Is this a link spam update?
Google has not labeled the September 2026 update as a link spam update.
It was announced as a general spam update.
Google has historically identified link spam updates separately when the update specifically relates to systems that neutralize manipulative linking practices.
Until Google says otherwise, the September rollout should not be described as a link spam update.
How much impact has the September 2026 spam update had so far?
There are two different things worth separating here: what Google has actually confirmed and what third-party tracking tools or SEO professionals are observing.
What Google has confirmed
Google has confirmed that:
- The update began September 24.
- It applies globally.
- It applies to all languages.
- It may take up to two weeks.
- It is a spam update.
Google has not confirmed:
- A specific spam tactic being targeted.
- Which industries are most affected.
- What percentage of search results changed.
- Whether AI content is a specific target.
- Whether links are a specific target.
That leaves a lot of room for speculation, which is exactly why early conclusions should be treated cautiously.
What SEO tracking tools are showing
Third-party ranking trackers showed significant volatility around the first few days of the update, with movement becoming particularly noticeable on September 26 and continuing through the weekend.
Search Engine Roundtable reported elevated movement across several major volatility tools, including Semrush, MozCast, AccuRanker, Similarweb, Sistrix, and others.
Those tools are useful for identifying broad changes in search results.
They cannot tell us exactly why the rankings changed.
High volatility does not prove:
- Every website was affected.
- Every decline was spam-related.
- One specific policy was targeted.
- One type of content caused the movement.
They tell us that search results are moving.
The diagnosis comes afterward.
What website owners are reporting
SEO communities have also reported unusually large ranking changes across some websites and industries.
Those reports can eventually help reveal patterns.
At this stage, they are still anecdotal.
One site losing 70% of its traffic does not prove what Google changed. One site gaining 200% does not prove which tactic Google rewarded.
The more useful analysis will come after the rollout has progressed further and enough affected websites can be compared.
Why has Google released four spam updates in 2026?
The September rollout is Google’s fourth confirmed spam update of 2026.
The previous three were:
- March 2026 spam update — approximately 19 hours and 30 minutes
- June 2026 spam update — approximately 2 days and 1 hour
- August 2026 spam update — approximately 2 days and 16 hours
- September 2026 spam update — still rolling out
The September update is notable because Google gave it a much longer expected rollout window than the previous three.
That does not necessarily mean the update is “bigger.”
Google has not said that.
Google’s spam systems operate continuously, and announced spam updates represent notable improvements to those automated systems.
Four updates in one year tells us Google is continuing to adjust its spam-detection technology. It does not tell us that one particular form of SEO is being targeted more aggressively without additional evidence.
What should you do if your rankings dropped during the September spam update?
Start by figuring out what actually changed.
Do not start with the assumption that the entire website needs to be rebuilt.
Do not panic during the rollout
Avoid immediately:
- Rewriting the entire website
- Deleting large sections of content
- Changing every page title
- Moving domains
- Redesigning the site
- Disavowing backlinks randomly
- Publishing large amounts of replacement content
The rollout is still active.
You may be reacting to temporary movement rather than a settled ranking change.
Large, irreversible changes also make later analysis harder because you no longer know whether the update or your own changes caused the next movement.
Annotate September 24 in Google Search Console
Mark September 24 as the beginning of the rollout in your SEO reporting.
Then compare performance around that date.
Look at:
- Clicks
- Impressions
- Average position
- Queries
- Landing pages
- Countries
- Devices
Sitewide organic traffic is useful, but it is not enough.
You want to understand which part of the website moved.
Compare affected pages and directories
Break the site into sections.
For example:
/blog/
/services/
/locations/
/products/
/categories/
Then ask:
Did everything decline?
Or did one directory lose visibility while everything else remained relatively stable?
A 25% sitewide traffic drop could come almost entirely from one blog category.
That tells you much more than the sitewide percentage alone.
Separate ranking losses from demand changes
Traffic can decline for reasons other than rankings.
Check whether:
- Impressions declined.
- Rankings declined.
- Click-through rate changed.
- Search volume changed.
- Seasonality changed.
- Paid search campaigns changed.
- Branded search demand changed.
If impressions and rankings remain stable but clicks fall, you may be looking at a SERP or demand issue rather than a ranking penalty.
If impressions collapse across a specific group of pages while crawling and indexing remain stable, that gives you a different starting point.
Review Google’s spam policies
Google’s direct guidance for websites affected by a spam update is to review its spam policies and make sure the website complies.
Do not review those policies simply to find one sentence that proves your website is innocent.
Use them as an audit framework.
Look at the areas of your site that actually lost visibility and ask whether the content or tactics involved could reasonably fall into one of Google’s spam categories.
What content should you review after a spam update?
A ranking decline does not mean every page needs to be rewritten.
Start with the affected parts of the website.
Scaled content
Look for content that exists primarily because a keyword existed.
Examples can include:
- Hundreds of nearly identical pages
- AI-generated articles published with little review
- Thin service-area pages
- Automatically generated category pages
- Pages created for slight keyword variations
- Large content libraries with little original information
Scale itself is not the problem.
A website can legitimately have thousands of useful products, locations, articles, or database pages.
The problem is scaling content primarily to manipulate rankings without providing meaningful value.
Duplicate and scraped content
Review pages that heavily rely on information available elsewhere.
Ask whether they:
- Copy competitor content.
- Aggregate other sources without adding anything.
- Rephrase existing articles without new insight.
- Repeat manufacturer descriptions.
- Duplicate large portions of other pages on the same site.
Referencing information from another source is normal.
Publishing a new page that adds essentially nothing is different.
Doorway pages
Doorway abuse is particularly relevant to local SEO.
Having separate location pages is not automatically spam.
A company genuinely serving multiple areas can have individual pages for those locations.
The problem is creating large numbers of substantially similar pages primarily to capture city-specific searches and funnel everyone toward the same generic destination.
A strong location page should have a real reason to exist.
That could include:
- Services available in that area
- Relevant examples
- Local experience
- Location-specific FAQs
- Projects
- Staff
- Service information
- Useful regional context
Changing only the city name across 200 pages is a very different strategy.
Keyword stuffing
Review whether keywords are being repeated unnaturally.
Common areas include:
- Headings
- Body copy
- City lists
- Footer text
- Internal-link anchor text
- Image alt text
- Titles
If a paragraph sounds ridiculous when read aloud because the target keyword appears every other sentence, that is usually a sign the optimization went too far.
Site reputation abuse
Site reputation abuse generally involves third-party content being published on an established website primarily to benefit from that site’s existing ranking signals.
A well-established domain should not become a place where unrelated content is published simply because the domain already has authority.
The question is whether the content genuinely belongs within the site’s purpose and whether the publisher is meaningfully involved in it.
Paid or manipulative links
Review backlink strategies built primarily around manipulating rankings.
That can include purchased links, excessive link exchanges, automated links, low-quality network placements, or other links designed primarily to pass ranking signals.
This does not mean backlinks caused a decline during the September update.
Google has not identified September as a link spam update.
The point is simply that manipulative link practices are already part of Google’s spam policies and should be reviewed when auditing overall compliance.
Can a legitimate website lose rankings during a spam update?
Yes.
Ranking changes during a spam update do not automatically prove that a website intentionally violated Google’s policies.
Google’s ranking and spam systems are automated.
At the same time, a website owner saying “we do not spam” is not enough to conclude that Google made a mistake.
Several things can happen during an update:
- Competitors can move above you.
- Query interpretation can change.
- Previously credited signals can lose influence.
- A group of pages can be reevaluated.
- Search intent can shift.
- Rankings can fluctuate while rollout continues.
- A website can use tactics the owner did not realize conflicted with Google’s policies.
The correct response is investigation.
Do not begin with “Google penalized us unfairly.”
Do not begin with “our website must be spam.”
Start with the data and determine what actually changed.
How long does recovery from a Google spam update take?
Recovery can take months.
Google says that after a site makes changes, its automated systems may need time to learn that the website now complies with its spam policies.
That means fixing a problem today does not guarantee rankings return next week.
If a site genuinely violated a spam policy, recovery may involve:
- Identifying the issue.
- Removing or improving the problematic behavior.
- Allowing Google to recrawl affected content.
- Continuing to comply with the policy.
- Waiting for automated systems to reassess the site.
There is not necessarily a manual reconsideration request for an algorithmic ranking change.
Recovery also does not always require waiting for a specific named update, but meaningful reassessment can take time.
Link spam is different
Link spam deserves an important distinction.
When Google’s systems neutralize ranking credit from spammy links, removing those links does not necessarily restore the previous ranking benefit.
The benefit came from links Google now considers invalid.
If those signals stop counting, the previous value cannot simply be reclaimed by removing the links.
That is different from correcting a content or site-quality issue and waiting for the site to be reassessed.
What should you not do during the September 2026 spam update?
Avoid making decisions based on panic.
Do not:
- Diagnose the entire update from one keyword.
- Assume someone else’s recovery tactic will fix your website.
- Delete useful pages because traffic moved for three days.
- Buy links to compensate for lost rankings.
- Mass-publish replacement content.
- Assume AI usage itself caused the decline.
- Assume every ranking loss means Google considers the site spam.
- Make a domain migration during an unfinished update without another legitimate reason.
- Change dozens of unrelated variables at once.
The goal is to preserve enough stability that you can actually analyze what happened.
What does the September spam update mean for AI-generated content?
AI-generated content is not automatically spam.
Google’s concern is whether content is being created primarily to manipulate rankings while providing little value to users.
That applies regardless of whether the content came from:
- AI
- Automation
- Freelancers
- Internal writers
- Agencies
- Scripts
- Data feeds
AI can be part of a legitimate content workflow.
A stronger process includes:
- Human review
- First-hand experience
- Original examples
- Unique data
- Subject expertise
- Accurate sourcing
- Fact checking
- Editing
- Real business context
- A clear reason for the page to exist
If AI helps a subject-matter expert create a genuinely useful resource faster, that is very different from generating 20,000 pages because a keyword tool found 20,000 variations.
The method matters less than the purpose and result.
What does this update mean for local businesses?
Local businesses should pay particular attention to how location-based content is being created.
Common areas worth reviewing include:
- Thin city pages
- Repetitive service-area pages
- Keyword-stuffed local pages
- Large city lists added for rankings
- Doorway-style regional pages
- Mass-generated local content
- Fake or manipulated reviews
- Pages with no unique local information
This does not mean local landing pages are a bad SEO strategy.
A properly built location page can be extremely useful.
If a plumbing company genuinely serves Toms River, Brick, Freehold, and Howell, separate pages can help explain the services available in each market and give searchers a more relevant destination.
The issue is when hundreds of pages are generated with essentially the same text and exist only to capture variations of:
service + city
The stronger approach is to make each important location page genuinely useful to someone searching from that area.
How Envision approaches Google spam updates
When a Google update rolls out, we try not to begin with theories.
We begin with data.
Our process generally looks like this:
- Confirm when the update started.
- Annotate the date in Search Console and analytics.
- Identify which pages and queries actually changed.
- Compare clicks, impressions, rankings, and conversions.
- Separate indexing or crawling problems from ranking changes.
- Look for patterns across page types and directories.
- Review the affected content against Google’s spam policies.
- Avoid making unrelated sitewide changes.
- Make improvements when there is evidence supporting them.
- Continue monitoring through the remainder of the rollout.
A blog directory losing traffic requires a different investigation than an entire domain disappearing.
A group of location pages declining requires a different analysis than a homepage losing two positions for one competitive query.
The more precisely we can define what changed, the easier it becomes to decide whether anything actually needs to be fixed.
