UK Competition and Markets Authority requires Google to let publishers opt out of AI-generated search summaries and training datasets

The UK Competition and Markets Authority ruling requires Alphabet's Google Search to provide publishers with the ability to opt out of both AI-generated search summaries and inclusion in training datasets, and to provide clear attribution and links to publisher content within AI search results.

The ruling applies to Alphabet's UK operations and includes testing new tools that give publishers more control over how their content is used in AI-powered search features.

For Alphabet, the decision introduces product and compliance complexity, requiring the company to balance AI Overviews, ad formats, and traffic flows while respecting opt-outs from publishers who may use the new controls as leverage in licensing negotiations.
