Google launched AI Performance Insights inside Merchant Center on 28 May 2026, alongside a new product-data field called Conversational Attributes. Both are aimed at the same problem: retailers can’t see how their products perform inside AI shopping experiences, and so they can’t optimize for them.
The launch matters. It also has a specific blind spot worth naming out loud.
What changed
AI Performance Insights gives Merchant Center accounts a four-module report: share of voice on AI surfaces, shopping-funnel performance across discovery / evaluation / purchase, product attribute insights with a completeness score, and benchmarks against similar brands. Conversational Attributes lets retailers add long-form, natural-language product data that Google’s AI systems can match against conversational queries.
Rollout starts in the US, Canada, Australia, New Zealand, and India “in the coming months.” Conversational Attributes are rolling out globally.
Per Google’s Marketing Live announcement, the share-of-voice module benchmarks visibility “on AI-driven experiences across Search and Gemini.”
That last phrase is the one to read carefully.
What it means for Shopify stores
Three actions worth taking this week.
First, request access to AI Performance Insights as soon as it lands in your region. The product-attribute completeness score is the highest-leverage piece of the report because it tells you exactly which structured fields are missing, and structured fields are what AI systems pull from.
Second, start populating Conversational Attributes for your top 20 SKUs. The format is closer to how a shopper actually types into ChatGPT or AI Mode (“a lightweight charcoal face wash for oily skin in your 20s”) than the traditional spec-sheet format Merchant Center has historically rewarded. Brands that ship this first will get cited disproportionately while everyone else figures out the new schema.
Third, audit which AI surfaces you actually need visibility on. Google’s report covers Google Search AI Mode and Gemini. It does not cover ChatGPT, Claude, Perplexity, or Grok. For Shopify merchants in men’s grooming, beauty, supplements, and other discovery-heavy verticals, ChatGPT and Perplexity drive a meaningful share of high-intent shopping conversations. You need a second instrument for those.
The contrarian read
The headline read on this launch is “Google validates AI search SEO as a category.” That’s true, and helpful for anyone trying to get a budget conversation past a CMO who still thinks “AI search” means “Google’s new search feature.”
The contrarian read is that Google just shipped the version of this tool a brand owner would have built if they only cared about Google. Which is the version Google was always going to ship.
We ran a pro-tier Citelix scan on Black Wolf Nation earlier today across ChatGPT, Gemini, Claude, Perplexity, and Grok. Black Wolf scored a 28.6% mention rate, but every single mention came from a head-to-head prompt that already named the brand. On 10 discovery prompts where the buyer didn’t know the brand, 0 mentions across 50 responses. Lumin won those slots. That’s the exact gap a share-of-voice tool needs to surface. Google’s tool will show you the Gemini half of that picture. The other 80% of the AI surface area is still your problem to instrument.
What we will be watching for next
Whether the share-of-voice benchmark Google ships exposes the brand-aware vs discovery prompt split, or just rolls everything up into a single mention-rate number. The single number is what most tools default to. The split is where the actionable signal lives.
