Google Merchant Center optimization
Research published by Search Engine Land and Peec AI confirms that ChatGPT fires “shopping fan-out queries” directly to Google Shopping’s organic results when generating its product carousel. The candidate pool for the carousel is effectively the top 40 organic Google Shopping positions for the relevant query. That means your Google Merchant Center feed is the single most important asset you control.
A winning GMC feed for ChatGPT carousel inclusion needs: an accurate, keyword-rich product title (leading with the most important attribute); a description of 500–1,000 characters that uses the language shoppers type conversationally; up-to-date pricing and availability; a GTIN or MPN where applicable; and at least one high-resolution image. Products with incomplete feeds are filtered out before ChatGPT ever sees them. Check your feed health weekly in Merchant Center and resolve every disapproval.
