Google Considers Opt-out for AI Overviews and AI Mode
Google is reportedly evaluating an opt-out mechanism for content used in its AI Overviews and AI Mode features, potentially allowing publishers to block their sites from being used in AI-sourced results. The move comes amid regulatory scrutiny from the UK Competition and Markets Authority (CMA), which seeks to give publishers greater control over AI-generated search content. Google has signaled updates to its controls to let sites opt out of Search Generative AI features, while stressing that such changes should not degrade search usefulness. The article notes publishers’ tensions between preventing AI usage of their content and avoiding full deindexing, and mentions Cloudflare’s standard protection against AI crawlers alongside proposals for a pay-per-crawl model. Publishers would also use Content Signals Policy to exclude content from AI services without harming indexation. The piece discusses potential impacts on traffic, impressions, and clicks if opt-outs are rolled out.

Google Offers Publishers AI Opt-Out Amid Ongoing Concerns
Following a UK Competition and Markets Authority (CMA) consultation, Google has agreed to develop controls allowing publishers to opt out of generative-AI features in Google Search, including being cited in 'AI Overviews' or used for wider model training. Publisher responses to the CMA (including the BBC, Financial Times, Guardian Media Group, DMG Media and trade bodies) welcomed greater control but warned that effectiveness depends on design choices — notably separation of AI crawlers from standard search crawlers, granular opt-in/opt-out by use case (grounding, training, fine-tuning), and protections against Google accessing publisher content via third-party dataset deals. Views differ on default settings: some publishers and trade groups want publishers opted out by default, while Google contests the claim that its AI features harm publishers.
Google AI opt-out leaves publishers with unusable choice
The U.K. Competition and Markets Authority (CMA) has ordered Google to give publishers greater control and transparency over how their content is used in AI search—including opt-outs from AI Overviews, AI Mode, AI summaries in Discover, clearer attribution, reporting, and an opt-out from model training. Google says it will roll out an opt-out toggle globally via Search Console and has nine months to implement changes. Publishers and industry figures warn the remedy is effectively unusable: the system is default opt-in, Google is not providing AI-specific click data necessary to judge impact, and multiple services may be bundled under a single toggle. Many publishers fear they will remain opted in due to competitive pressure and lack of granular reporting. The CMA says it will monitor implementation and may take further action if necessary.
Publishers can opt out of Google AI Search
The U.K. has enacted rules requiring Google to provide website publishers with a way to opt out of being aggregated into its generative AI search features. Google announced compliance and will add a toggle in Search Console that, when enabled, excludes a publisher’s site from AI Overviews, AI Mode and AI Overviews in Discover. The feature will be tested with a subset of U.K. publishers before a global rollout. The Competition and Markets Authority (CMA) called the measure a “world first,” saying it strengthens publishers’ negotiating position for content use and training. Google must also ensure clear attribution links in AI responses and says opting out will not affect traditional search ranking. Google will add new Search Console metrics showing which pages appear in AI responses and in which countries.
