Google’s September 2026 spam update began on September 24 and finished on October 8, affecting search results worldwide across all languages. With the rollout complete, website owners can now assess performance changes against the confirmed update period.
For businesses, the useful question is whether their SEO practices create lasting value for visitors—and what to investigate if visibility has declined.
What Does a Google Spam Update Do?
Google continuously operates automated systems to identify search spam. A spam update introduces significant improvements to those systems, helping Google detect practices intended to manipulate search results.
Google advises websites affected by these updates to review its spam policies. Violations can result in lower rankings or exclusion from search results.
The September announcement did not identify a specific tactic being targeted. Claims that this update exclusively targeted AI content, backlinks, or a particular industry should therefore be treated cautiously.
Which Website Practices Deserve Attention?
The following are established policy areas worth reviewing—not confirmed targets unique to the September update.
| Area | What to review |
|---|---|
| Scaled content abuse | Large volumes of pages created mainly to manipulate rankings, with little original value. |
| Keyword stuffing | Unnatural repetition of keywords, locations, or phrases. |
| Link spam | Links bought, exchanged, or generated primarily to influence rankings. |
| Doorway abuse | Similar pages targeting related searches that funnel visitors elsewhere without sufficient usefulness. |
| Hacked content | Unauthorized pages, injected links, or malicious redirects. |
These practices are covered by Google’s published spam policies.
Does Using AI Put Your Website at Risk?
Google’s scaled content policy focuses on purpose and value, regardless of how content is produced. Generating many pages with AI without adding value can violate the policy, but AI use alone does not establish a violation.
Practical insight: Build an editorial review into your publishing process. Check factual accuracy, remove unsupported claims, and add information your business can contribute directly.
For a manufacturer, that could include product testing, application guidance, material comparisons, or answers from technical staff. These details give potential buyers a reason to read your page.
How to Review a Drop in Organic Traffic
A decline that coincides with an update is a reason to investigate. Timing alone does not establish the cause.
A practical review should include:
Compare equivalent periods. Examine performance before and after the rollout, accounting for weekday patterns and seasonal demand.
Find the affected pages. Determine whether losses are concentrated in blogs, product pages, location pages, or the whole website.
Separate performance signals. Review clicks, impressions, click-through rate, and average position together.
Check recent website changes. Investigate redirects, indexing settings, deleted pages, outages, and tracking changes.
Review policy risks. Examine the affected sections for practices covered by Google’s spam policies.
Keep a record of your findings and changes. This makes subsequent performance comparisons more useful than repeatedly editing pages without a clear diagnosis.
An Important Lesson for B2B Websites
For manufacturers, exporters, and service providers, a useful audit question is: Does each landing page help a buyer make a distinct decision?
A page targeting distributors in a particular country could explain shipping arrangements, applicable product specifications, partnership requirements, and available support. Simply changing the country name across dozens of otherwise identical pages adds little practical value.
This is an editorial recommendation, not evidence that Google specifically targeted B2B landing pages in this update.
The same approach applies to product content. Consider adding selection criteria, limitations, maintenance guidance, or genuine application examples instead of repeating a generic description.
How Long Can Recovery Take?
Google says improvements may take months as its automated systems learn that a website complies with its spam policies. Fixes do not guarantee an immediate return to previous rankings.
Prioritize verified problems, document the corrections, and monitor affected page groups over time. Measure qualified enquiries and conversions alongside search visibility so that recovery work stays connected to business results.
A useful next step is to review your highest-value landing pages and your largest groups of templated content. Identify where visitors need better answers, where technical issues prevent access, and where publishing practices need correction.
