Merchant Center and product feed experts

A Merchant Center account shows an approval rate, and that figure reassures for the wrong reasons. We regularly see catalogues approved above 98 %, with no alerts at all, that send around twenty attributes out of the fifty the specification allows: descriptions cut by the connector well below the 5,000-character limit, no additional images although the product page hosts a dozen, no manufacturer GTIN, a single-level product type. The feed is compliant. It is poor. And a system choosing between two comparable products picks the one it understands.

On this subject, Google's documentation is more sober than the surrounding discourse. It writes that there are no additional requirements nor special optimizations to appear in AI Overviews or AI Mode: an indexed page eligible for a snippet is enough, and on the merchant side, an up-to-date feed. The same documentation adds a section dismantling fashionable recipes, noting that Google Search ignores llms.txt files. What Google actually asks is written elsewhere, in its advice on AI performance reports: put the relevant search terms into titles and descriptions, and fill in the missing attributes.

This is the part French content does not tell. The agentic commerce protocol and checkout inside Google surfaces cover only the United States, Canada and Australia, on an allow list and under US terms of service. The conversational business agent requires a US-based store. And the report that would measure your visibility in AI answers exists only in English, across five countries that do not include France. With no measurement tool available in Europe, we do not sell an AI visibility promise. What can be switched on here, and what we work on: the six conversational attributes, shipping and returns transparency, the loyalty programme since March 2026, and catalogue completeness, which already pays in Shopping and Performance Max.
