It covers share of voice against similar brands, shopping funnel performance, product term insights, and product attribute gaps. Google announced it 20 May 2026 for the US, Canada, Australia, India and New Zealand. ## Key takeaways - Google announced AI performance insights for Merchant Center on 20 May 2026, alongside conversational product attributes. - Share of voice benchmarks a brand's visibility on AI-driven shopping experiences against similar brands, which the Help page ties to the merchant's Merchant Center competitor set. - Shopping funnel performance breaks results into discovery, evaluation and ready-to-buy stages of the shopping journey. - Product term insights show popular search terms and the merchant's share of voice for each one. - Product attribute insights list popular specifications, such as size, color or material, that may be missing from the merchant's product data. Merchant Center is getting a dedicated report for the part of shopping search that used to be invisible: what happens when a product shows up inside an AI Mode answer or an AI Overview instead of a standard search results page. Google announced AI performance insights on 20 May 2026, alongside a separate feature for conversational product attributes, and framed both as tools for a shopping journey that increasingly starts as a conversation rather than a keyword. ## The four things the report measures Google's Merchant Center Help documentation describes the report in four parts, which we have grouped and labelled ourselves. Each addresses a different blind spot in AI-driven shopping traffic. **Share of voice** shows a brand's visibility on AI-driven shopping experiences, benchmarked against similar brands. The Help page defines it as the brand's AI impressions divided by total impressions across its Merchant Center competitor set. It is the headline metric: not raw impressions, but a competitive share. **Shopping funnel performance** breaks results into the stages of a shopping journey Google already uses to classify conversational queries: discovery, evaluation and ready to buy. A merchant can see whether they show up when someone is exploring options, comparing specifications, or close to buying. **Product term insights** surface the popular product terms searched by users in AI conversations, alongside the merchant's share of voice for each term. This is closer to a conversational-query report than a keyword report. **Product attribute insights** list the specifications customers look for, such as size, color or material, that may be missing from your product data sources. ## Rollout markets and limits Google's own blog post and Search Engine Land's coverage both describe the rollout as reaching the United States, Canada, Australia, India and New Zealand, arriving "in the coming months" rather than simultaneously. Google's Merchant Center Help page confirms the same five markets and adds two limits worth noting before treating the numbers as complete: the data currently covers English-language queries only, and it is strictly limited to organic AI traffic, such as free listings, with Paid Ads traffic excluded. This is a separate story from the [2026 Merchant Center product data specification update](/news/merchant-center-product-data-spec-2026), which changed shipping and video attributes and the minimum image resolution. AI performance insights adds a reporting layer on top of the same catalog; it does not change what a merchant is required to submit. ## Why we care Share of voice is the metric that matters here, because it puts a competitive number on visibility in AI surfaces, measured against similar brands for the same conversational queries. Combined with product attribute gaps, the report gives merchants a concrete lever: fill in the missing attributes it flags, as Google's help page recommends, and watch whether share of voice moves. Until the English-only, organic-only limits lift, though, treat the numbers as a partial view rather than the full picture of AI shopping performance. ## Common questions ### What does share of voice measure in AI performance insights? It measures the percentage of impressions a brand receives on AI Mode and AI Overviews compared with the competitors defined in its Merchant Center account. It is a relative benchmark, not a standalone visibility count. ### Which countries get AI performance insights first? Google announced the rollout for the United States, Canada, Australia, India and New Zealand on 20 May 2026, describing it as arriving "in the coming months" rather than all at once. Google's own help center confirms the same five markets, currently for English-language queries only. ### Does the report include paid Shopping ads traffic? No. Google's Merchant Center help documentation states the report is strictly limited to organic AI traffic, such as free listings, and does not include Paid Ads traffic. ## Sources 1.
