Google's September spam update is rolling out. A demotion now costs you the AI answer too.

Google began rolling out its September 2026 spam update on September 24, 2026, and from that date a spam demotion no longer costs a site its blue links alone: it costs the site its place in Google's AI answers, because AI Overviews and AI Mode draw on the same index as ordinary search.

What exactly did Google announce on September 24, 2026?

Google released the September 2026 spam update on September 24, 2026 at 9:15 a.m. Pacific time, globally and across all languages. Google's own status dashboard gives the rollout a window of up to two weeks, the longest of the four spam updates Google has shipped in 2026 (March, June, August, September). Google named no specific tactic and described the release as a normal spam update.

A spam update is not a quality update, and the difference decides how you respond. A quality update re-assesses how useful a page is, which you fix slowly and page by page. A spam update looks for practices Google has written down in its published policies and demotes the sites using them, which you fix by removing the practice.

What does this change for a small business?

For a small business, the change is that a banned practice now carries a price on two surfaces instead of one. Google's spam policies explicitly cover techniques that attempt to manipulate generative AI responses in Google Search, and Google's own documentation states that there are no additional requirements to appear in AI Overviews or AI Mode: a page simply needs to be indexed and eligible to be shown in Google Search with a snippet. A site demoted for spam therefore loses the blue links and the AI answer in a single move.

The cost of the search side is already measured. Ahrefs compared December 2023 with December 2025 across 300,000 keywords and found that the click-through rate of the number one position is 58% lower when an AI Overview is shown. A business that loses its place in the AI Overview and slips a few positions in the organic links absorbs both losses on the same query, on the same day.

The two surfaces also reinforce each other in the other direction, which is the part most owners miss. A page that is eligible for a snippet is eligible to feed an AI answer, with no separate application, no markup unique to AI and no waiting list. Eligibility in Google Search is the entry ticket, and a spam demotion is the one thing that revokes both tickets at once.

Is content published at volume to "get cited by AI" in scope?

Content published at volume to get cited by AI falls under a policy Google already names: scaled content abuse. Google defines scaled content abuse as generating many pages for the primary purpose of manipulating search rankings rather than helping users, and the documentation specifically lists using generative AI tools or other similar tools to generate many pages without adding value for users. The GEO (Generative Engine Optimization) packages sold since 2025 on a promise of forty new pages a month describe themselves in Google's own words.

The distinction worth holding is that Google is not penalising the writing tool, it is penalising volume without contribution. An article drafted with AI assistance, then checked, sourced and signed by a named person, is not what this policy describes. Forty pages repeating one promise with the town name swapped is exactly what it describes. Google's test is what the page adds for the reader, never how the words were produced.

Your traffic dropped after September 24: what should you do, and in what order?

A drop measured since September 24, 2026 is not yet a verdict, because the rollout Google announced runs into early October 2026. Rankings can rise and fall again inside a rollout window, and a hasty reaction deletes pages that were never the problem. Our article "How long before you see an effect on your AI visibility?" sets out why that waiting period is a method rather than an excuse.

• Wait for the rollout to finish before drawing a conclusion, roughly two weeks after September 24, 2026.
• Read the two surfaces separately: organic positions on one side, appearances in AI answers on the other. Our article "Google just opened its AI visibility report to every site. It counts impressions, not clicks." covers what that report counts and what it leaves out.
• Take an honest inventory of the pages you published at volume over the past twelve months, and ask what each one adds that another page on the site does not already cover.
• Confirm your pages are still indexable and snippet-eligible: a forgotten "noindex" or an over-broad "nosnippet" removes you from AI answers with no penalty involved at all.

Should you change your AI visibility strategy this week?

The September 24, 2026 update does not change what makes a site readable by an AI, it changes the price of cheating. The useful signals are the same ones as last month: content that answers one precise question, a structure a machine can cut into self-contained passages, and public files that state plainly who you are and what you sell. Our published method lists those signals on /en/methode.

What does change is the trade-off between volume and standing. Publishing less and better becomes a commercial decision as much as an editorial one, because a volume tactic now exposes both traffic sources to the same demotion. A site with ten solid pages has nothing to fix this week. A site with three hundred generated pages has an inventory to run before the rollout ends.
