Google’s September 2026 spam update has finished rolling out, and website owners and SEO professionals are now checking their traffic to see what changed. The Google Search Status Dashboard confirms that the update began on September 24, applied globally and to all languages, and was completed on October 8, 2026.
Here is the important part: Google’s announcement confirmed the rollout dates, but it did not identify a new individual spam policy or explain which specific signals changed. That leaves many businesses asking the same question. If Google did not say what it targeted, how do you protect your website?
The answer is to understand Google’s existing spam policies, know which practices put your site at risk, and build an SEO strategy that does not depend on shortcuts. This guide covers all three.
What Happened in the September 2026 Spam Update
Here is what is officially confirmed:
- Start date: September 24, 2026
- Completion date: October 8, 2026
- Scope: Global, all languages
- Duration: Roughly two weeks, one of the longer spam update rollouts in recent history
- Policy details: Google did not name a new policy or list the specific signals that changed
Google described spam updates as improvements to its automated systems that detect search spam. These systems run all the time, but Google occasionally makes notable upgrades, and a spam update is how it announces them. Google’s guidance for sites that see a change is to review its spam policies and make sure they are fully compliant.
Because the details are limited, it is better not to guess at exactly what changed. Treat anyone claiming to know the precise trigger with caution. What you can do is audit your site against the policies Google has already published.
How Spam Signals Affect Search Visibility
When Google’s systems identify spam, the effect on a website can show up in a few different ways:
- Automated demotion: Pages or whole sections of a site can lose rankings without any notification
- Removal from results: In more serious cases, pages may stop appearing in search at all
- Manual actions: A human reviewer at Google can apply a penalty, which appears in the Manual Actions report in Google Search Console
- Lost trust over time: Sites with repeated spam signals may find it harder to rank even for legitimate content
One point matters for planning. Google has said that recovery from spam related changes can take months, because its systems need to re-evaluate a site over time. A quick fix does not usually bring rankings back overnight, which is why prevention is far cheaper than recovery.
Google’s Spam Policies: What Website Owners and SEO Professionals Should Avoid
Google publishes a list of spam practices that can lead to lower rankings or removal from search results. Here are the main ones, explained in plain language.
1. Scaled Content Abuse
This means producing large volumes of content mainly to manipulate rankings rather than help users. It applies whether the content is written by AI, by humans, or by a mix of both. Publishing hundreds of near identical location pages or mass produced blog posts with no real value is a common example.
What to do instead: Publish fewer, better pages with original insight, real examples, and a clear purpose for the reader.
2. Link Spam
Buying links, exchanging links excessively, using automated link building tools, or placing links in low quality directories and comments all fall into this category. Links that exist only to pass ranking value can be treated as spam.
What to do instead: Earn links through useful content, digital PR, and genuine partnerships. Our team can help with Digital PR Services that build real authority the right way.
3. Keyword Stuffing
Repeating keywords unnaturally, or loading a page with lists of cities, phone numbers, or terms that add no value, is a long standing violation.
What to do instead: Write naturally for people, using the main keyword and related terms where they genuinely fit.
4. Cloaking and Sneaky Redirects
Showing search engines one version of a page and users another, or redirecting visitors to a page they did not expect, breaks Google’s rules. This sometimes happens by accident through poorly configured redirects or plugins.
What to do instead: Make sure users and Googlebot see the same content, and review your redirect rules regularly.
5. Doorway Abuse
Doorway pages are created to rank for specific search phrases and then funnel users to the same destination. Many near identical “service in [city]” pages built purely for rankings can fall under this.
What to do instead: Create location or service pages only when each one offers distinct, useful information.
6. Expired Domain Abuse
Buying an expired domain mainly to take advantage of its past authority and publishing unrelated, low value content on it is treated as spam.
7. Site Reputation Abuse
This happens when third party content is published on a trusted site mainly to take advantage of that site’s ranking signals, with little oversight from the host site. Examples include unrelated coupon, payday loan, or review sections added to an established site.
8. Thin Affiliate Pages
Pages that copy product descriptions from other sources and add no original value for users are a risk, especially on affiliate sites.
9. Hidden Text and Links
Text that is invisible to users but readable by search engines, such as white text on a white background, remains a clear violation.
10. Scraping and Auto Generated Spam Content
Copying content from other websites with little or no original contribution, or generating text without quality control, can lead to demotion.
11. User Generated Spam
Spammy comments, forum posts, and profile pages on your own site can hurt you if left unchecked.
What to do instead: Use moderation, spam filters, and the nofollow or ugc link attributes on user submitted links.
12. Hacked Content and Malware
If your site is compromised and used to host spam pages, malicious scripts, or injected links, your visibility can suffer quickly. Security is part of SEO.
A Note on AI Generated Search Features
Industry reports note that Google’s spam policies have also been extended to cover generative AI responses in Search, such as AI Overviews and AI Mode. The practical lesson is the same: content that is original, accurate, and written for people has the best chance of being trusted by both traditional and AI driven search.
How to Check Whether Your Site Was Affected
The update is complete, so this is the right moment to compare your data. Follow these steps:
- Open Google Search Console and compare performance from before September 24 with performance after October 8.
- Look at specific pages and queries, not just total traffic, to see where changes happened.
- Check the Manual Actions report for any penalties applied to your site.
- Review Security Issues to confirm there is no hacked or malicious content.
- Separate normal fluctuation from real drops. Rankings often move during a rollout, so wait until the update is fully complete before drawing conclusions. A small movement is not necessarily a penalty.
If you see a sharp, sustained drop concentrated on certain pages or sections, review those pages against the policies above.
What to Do to Protect Your Organic Rankings
Since Google did not publish new rules, your best protection is a clean, user focused site. Here is a practical plan.
Run a Full Site Audit
Start with a thorough review of your content, links, redirects, and technical setup. A professional Site Audit can reveal thin pages, duplicate content, suspicious links, and technical issues you may not notice.
Clean Up Your Backlink Profile
Review the links pointing to your site. If you have paid links or low quality directory links from past SEO work, remove them where possible, and keep a record of your cleanup efforts.
Improve or Remove Low Value Content
Pages that exist only to capture search traffic, and offer little help, should be improved, merged, or removed. Quality across your whole site matters more than page count.
Strengthen Technical Foundations
Clean redirects, correct canonical tags, secure hosting, and healthy crawling all reduce the chance of accidental spam signals. Our Technical SEO Services cover these details.
Invest in Original, Expert Content
Original research, real case studies, and clear expertise are hard to fake and easy for users to value. Professional Content Writing Services built around real search intent help you publish content that is useful instead of repetitive.
Monitor Regularly
Set up Search Console alerts, review your traffic after every confirmed Google update, and keep an eye on security. Early detection makes any fix much faster.
Common Mistakes Businesses Make After a Spam Update
- Panicking and deleting large amounts of content without checking what actually caused any drop
- Blaming the update without reviewing the site for genuine policy issues
- Buying more links to recover, which usually makes things worse
- Using AI to mass produce replacement content, which can create new scaled content problems
- Expecting fast recovery, when Google has said recovery can take months
Final Thoughts
The September 2026 spam update is complete, but the lesson is not new. Google rewards websites that help people and penalizes tactics that try to manipulate rankings. Because Google has not named a new policy or detailed the signals involved, the smartest response is to audit your site against the existing spam policies, fix genuine problems, and keep publishing original, useful content.
Sustainable SEO does not depend on loopholes. It depends on trust, quality, and a technically healthy website, which protect your rankings no matter which update Google releases next.
