Context
Google made Merchant Center AI performance insights available across five markets, measuring merchant share of voice across AI Mode and AI Overviews, while expanding Business Agent and Universal Commerce Protocol capabilities.
What changed
Merchant Center AI performance insights became available in Australia, Canada, India, New Zealand and the U.S.; Google also opened a U.S. beta for Business Agent in YouTube ads and expanded UCP integration capabilities.
Why it matters
This gives retailers a first-party measurement surface for AI shopping discoverability and connects product data, conversational discovery and agentic checkout within Google commerce workflows.
Visibility OS interpretation
Visibility OS interprets this as a shift from manually inferred AI shopping visibility toward platform-provided merchant measurement. Google also provides direct evidence that merchant-supplied conversational attributes can be incorporated into AI Mode product recommendations, but this does not establish a universal ranking factor.
What remains uncertain
Google does not disclose the complete ranking/recommendation system or the exact share-of-voice methodology. The reported lululemon test may not generalize across merchants or categories, and UCP capabilities vary by market and rollout stage.
