Google September 2026 Spam Update: What to Check
Google began rolling out the September 2026 spam update on 24 September at 09:15 PDT. The update applies globally and to all languages. Google says the rollout may take up to two weeks.
What has Google confirmed?
The official Google Search Status Dashboard confirms three facts: the rollout started on 24 September 2026, it covers all countries and languages, and it may take up to two weeks to complete.
Google has not named a particular industry, content format or spam technique as the main target of this update. Claims that it specifically targets one sector or one SEO tactic are therefore speculation unless Google publishes more detail.
This announcement is also not a study. It provides no sample, percentage impact or expected traffic change. A site may rise, fall or remain stable during the rollout, and movement at the same time does not by itself prove that the spam update caused it.
What is a spam update?
Google says its automated systems continually work to detect search spam. When it makes a notable improvement to those systems, it calls the change a spam update. SpamBrain is one of the AI-based systems Google uses for spam prevention, but Google has not said which individual system changed in September.
The relevant rules are broader than copied text or suspicious links. Google’s spam policies cover practices such as cloaking, doorway abuse, expired-domain abuse, hacked content, hidden text, keyword stuffing, link spam, misleading functionality, scaled content abuse and site reputation abuse.
The policies also apply to attempts to manipulate generative AI responses in Google Search. That means the same policy review matters for visibility across Google Search, including its AI-supported experiences. Compliance still does not guarantee a ranking or a citation.
How should you monitor the rollout?
- Mark the rollout window. Use 24 September as the start date and wait for Google to confirm completion before drawing conclusions about the full effect.
- Check Search Console by page and query. Compare clicks, impressions and average position with a comparable earlier period. Separate branded and non-branded queries where possible.
- Look for a pattern. Is a change limited to one directory, content type, country, language or group of queries? A site-wide conclusion from one page can be misleading.
- Check Manual Actions and Security Issues. An algorithmic spam update is different from a manual action, but these reports can reveal separate problems that need immediate attention.
- Review other explanations. Seasonality, demand changes, tracking problems, migrations and technical faults can also change organic traffic. Google’s traffic-drop guide recommends checking these possibilities.
What should you review on the site?
Start with areas where evidence points to a problem. Check whether important pages exist mainly to capture search traffic, repeat the same information at scale, hide ownership or authorship, or use third-party content without clear value for your audience.
Review outbound and inbound link practices, redirects, structured data, template-generated pages and content published through partners. Correct factual errors and remove unsupported claims. If a page serves a real customer need, improve that page rather than rewriting the entire site in response to a short-term graph.
Google notes that recovery may take time after a site corrects spam-policy violations because automated systems must learn that the site is complying. For link spam, removing the effect of spammy links does not restore the ranking benefit those links previously created.
What should you avoid during the rollout?
Avoid deleting large sections, changing URLs or replacing useful pages solely because of a few volatile days. These actions can create new indexing and measurement problems. Keep a change log so later analysis can separate update timing from your own edits.
There is no reliable “September update fix” that guarantees recovery. The practical approach is to identify a specific policy or quality problem, correct it, and measure the result over time.
Status and guidance checked on 26 September 2026. The rollout was still in progress. Google had not published sector-specific impact data or named a specific spam category for this update.
