CMA forces Google to let publishers opt out of AI Overviews
Updated: Aug 19
The UK's Competition and Markets Authority has required Google to give publishers a way to opt out of having their content pulled into AI Overviews — the AI-generated summaries that increasingly sit at the top of search results. In response, Google is testing tools that let website owners exclude their pages from these summaries without being penalised in traditional search rankings, a change expected to roll out globally.
The intervention addresses a tension that has been building for months. AI answers that summarise information directly on the results page can satisfy a user's query without them ever clicking through, eroding the traffic — and advertising revenue — that publishers and brands rely on. Until now, the only way to stay out of those summaries was to block Google's crawler altogether, effectively disappearing from search.
A new strategic choice
By decoupling AI summaries from search rankings, the CMA's move hands content owners a genuine decision for the first time: appear in AI answers and accept reduced click-throughs, or opt out to protect traffic to your own site. Neither option is universally right, and the best choice will vary by brand, content type and commercial model.
For SEO and content teams, it turns a technical frustration into a strategic question that belongs on the marketing agenda. Expect the trade-off between AI visibility and owned traffic to become one of the defining search debates of the next year.
The wider context: the end of the free click?
The ruling lands against a stark backdrop. Industry research suggests that fewer than a third of Google searches now end in a click to an external website, as AI-generated answers keep more users on the results page. For businesses that have spent two decades building their audiences through organic search, that shift represents an existential challenge to the traffic model many rely on.
The CMA's decision will not reverse that trend, but it does hand brands a measure of agency they did not have before. Rather than passively accepting how their content is used, publishers can now make a deliberate call — and, crucially, measure the consequences. That makes rigorous analytics more important than ever: without a clear view of how much traffic AI answers are actually costing, brands cannot make the trade-off intelligently.
The likely long-term response is a rebalancing of effort towards owned channels — email, communities, apps and direct relationships — that do not depend on a search engine's goodwill. AI search is not the end of SEO, but it is forcing a healthy reassessment of how much any brand should rely on a single, increasingly unpredictable source of traffic.

For marketers, the takeaway is to treat AI search as a deliberate channel choice, not an afterthought. Decide what role your content should play in AI answers — and measure the trade-off in real traffic.
Would you keep your content in Google's AI Overviews for visibility, or opt out to protect clicks to your own site?
