Does fixing product information for ChatGPT also help Gemini, Perplexity and Copilot?

Buyers ask this in almost every call: if we fix it for ChatGPT, does Gemini get better too? What about Perplexity and Copilot? The answer has three parts.

• Shared. Identifiers, availability, price parity, category attributes, page copy that answers the questions shoppers ask, structured data that matches the page, reviews and visible Q&A. Every assistant reads some combination of these from your product pages and feeds.
• Destination-specific. Feed eligibility flags, merchant policy fields, enrollment steps and a few attributes that only one destination defines.
• Always separate. Which products an assistant recommends for a given question. Each one ranks on its own logic, so one fix can lift ChatGPT appearances this month and Gemini appearances later, or the other way round.

ChatGPT

ChatGPT shopping results draw on the OpenAI product feed, on Shopify Catalog for eligible Shopify stores through agentic storefronts, and on your public product pages crawled by OAI-SearchBot. Shopify describes ChatGPT as a discovery channel where shoppers finish the purchase on your online store checkout.

Google AI Mode, AI Overviews and Gemini

Google's shopping answers use Google Merchant Center product data together with your indexed product pages. Google states there are no special requirements for AI features on Search beyond normal eligibility. Shopify stores reach Google AI Mode and Gemini through the Google and YouTube sales channel or a GMC account, and Shopify lists these surfaces as early access.

Perplexity

Perplexity answers and product cards are built from crawled pages and from product information shared through the Perplexity Merchant Program. Perplexity describes the program as free for merchants.

Microsoft Copilot

Copilot shopping draws on Microsoft Merchant Center. Microsoft asks merchants to improve product visibility in Merchant Center with a UCP-ready feed, including return policy and support settings and a unique Merchant Item ID. Shopify lists Copilot as an agentic storefront in early access, fed from Shopify Catalog.

• Identifiers. A valid GTIN where one is assigned, otherwise brand and MPN. Google, OpenAI and Microsoft all key on them, and Shopify Catalog carries them forward.
• Availability and price parity. The same values on the page, in GMC and in the OpenAI feed. A mismatch costs eligibility in one place and trust in another.
• Category attributes. Fit, material, dimensions, compatibility, ingredients. These are what shoppers ask about and what assistants compare on.
• Page copy that answers the questions shoppers ask. Visible text about who the product suits, what it works with and how to care for it. Crawled by every assistant.
• Structured data that matches the page. Product and Offer markup aligned with visible content and with the feed.
• Reviews and Q&A. Shown on the page and, where supported, passed in the feed. See product Q&A for AI shopping.

• OpenAI feed. The eligibility flags for search and checkout, seller fields, return policy and target countries defined in the feed specification.
• Google Merchant Center. Account verification, shipping and return settings, and the optional conversational attributes Google added for AI surfaces.
• Microsoft Merchant Center. Store settings for return policy and customer support, plus the UCP attributes Microsoft lists for Copilot.
• Shopify Catalog. Which channels may read your products, how product details map to Catalog fields and how variants group into one listing, all under Sales channels, then Agentic.
• Perplexity. Enrollment in the merchant program and the product information you choose to share through it.

Treat these as setup. The recurring work is the shared list above.

Shopify's own search preview tool carries a useful warning: agentic storefronts often re-rank results with their own logic, so what one surface shows can differ from another for the same question. The same applies across ChatGPT, Google and Perplexity. Measuring one assistant tells you about that assistant.

So the working method is simple. Run the same set of the questions shoppers ask on each assistant on a schedule, record whether your products appear and in what form, and fix the product information behind each miss in the source your feeds and pages are built from. This is how Paz runs AI visibility. Our experts track ChatGPT, Google AI Mode, Google AI Overviews, Gemini, Copilot and Perplexity, fix the catalog, feed and page information behind each gap within the guidelines you approve, and report appearances per assistant against your baseline.
