Google has finished rolling out its September 2026 spam update, the fourth spam update of the year and the longest one so far. If your website’s traffic moved in late September or early October, this update is a likely suspect. For Canadian small businesses that rely on Google to bring in calls, quote requests and store visits, it is a good moment to review how your site is built and promoted.
Here is what happened, what Google’s spam systems look for, and a practical checklist you can work through this week.
What happened: the key dates
According to the Google Search Status Dashboard, the update started on September 24, 2026 and was declared complete on October 8, 2026, a rollout of roughly 13 days and 16 hours. Google described it as a normal spam update applying to all languages and all locations, which means French and English sites in Quebec and across Canada were equally in scope.
Google did not announce any new spam policy with this update and did not say how many sites or queries were affected. Industry trackers reported noticeable ranking volatility around September 25–27, September 30 and October 4–6.
How it compares with the other 2026 spam updates
- March 2026: March 24–25, under a day.
- June 2026: June 24–26, about two days.
- August 2026: August 18–21, about three days.
- September 2026: September 24 to October 8, nearly two weeks.
Four spam updates in seven months sends a clear message: Google is refreshing its spam detection (including its SpamBrain system) more often, and it has said further periodic refreshes will follow.
What Google’s spam policies target
Spam updates enforce Google’s existing spam policies. The practices most relevant to small business websites include:
- Scaled content abuse: publishing large numbers of thin pages, often auto-generated, mainly to rank rather than to help visitors.
- Doorway pages: near-identical city or service pages that only swap a place name.
- Expired domain abuse: buying an old domain to profit from its past reputation with unrelated content.
- Site reputation abuse: hosting third-party content on a trusted site to borrow its authority.
- Fake or undisclosed incentivized reviews and back button hijacking.
Industry coverage noted that this cycle was not aimed at link spam specifically. That does not make low-quality links safe: Google’s position is that any ranking benefit gained from spammy links is simply lost.
Why this matters for Canadian small businesses
There is no warning and no appeal
Unlike a manual action, an algorithmic demotion comes with no message in Search Console and no reconsideration request. Many owners only notice when the phone stops ringing. That is why regular monitoring matters more than ever.
Cheap “SEO packages” carry real risk
Offers promising hundreds of AI-written blog posts or dozens of city pages for a low monthly fee are exactly the patterns spam systems are built to catch. If a provider cannot explain how each page helps a real customer, be cautious. Our guide on what SEO really costs in Canada (in French) explains what a legitimate engagement looks like.
Bilingual and multi-location sites need unique content
A Quebec business serving Laval, Longueuil and the Laurentides can absolutely have a page for each area. The difference between a helpful local page and a doorway page is substance: real projects, local details, team members, reviews and answers specific to that area.
A 7-point checklist after the update
- Compare traffic in Search Console for the two weeks before September 24 and the two weeks after October 8.
- Find thin pages: list pages with little original text or almost no visits, then improve, merge or remove them.
- Audit location pages for copy-paste content and add genuinely local information.
- Review AI-assisted content: every article should be edited, fact-checked and written for customers first.
- Check your reviews strategy: no paid, fake or gated reviews. See our guide to getting more Google reviews the right way (in French).
- Clean up old tactics: paid link packages, hidden text or pages created only for keywords.
- Run a technical audit to rule out other causes such as indexing errors or a slow site, using our SEO audit checklist (in French).
What if your traffic dropped?
First, confirm the timing. A drop that started before September 24 points to something else, such as a technical issue, a site redesign or seasonal demand. If the drop lines up with the rollout, focus on removing or fixing anything that conflicts with Google’s spam policies. Recovery is possible, but it is not instant: Google’s systems need time, often months, to recognize that a site now complies.
In the meantime, diversify how customers find you: an optimized Google Business Profile, email marketing and visibility in AI answers. Our article on appearing in ChatGPT and Google AI Overviews (in French) covers that last point. For a broader look at using AI responsibly in your business, AIZ Solutions publishes practical guides.
What comes next
Google has not announced a date for its next core or spam update, but 2026 has shown a steady rhythm. The safest long-term strategy has not changed: useful pages, honest reviews, a fast and secure site, and content written by people who know your trade.

FAQ
When did the September 2026 spam update finish?
It began on September 24, 2026 and Google confirmed it was complete on October 8, 2026, after about 13 days and 16 hours.
Will I get a notification if my site was affected?
No. Algorithmic spam demotions do not trigger a Search Console message. Only manual actions do. Watch your traffic and rankings instead.
How long does recovery take?
It can take several months after you fix the issues, because Google’s systems need time to confirm that your site follows its spam policies.
