Send conversational product data in the Merchant Center feed: Q&A, product details, highlights and related products

In 2026 Google added Merchant Center attributes intended mainly for conversational experiences such as AI Mode (question_and_answer, document_link, related_product and popularity_rank) and more flexible variant data (item_group_title and variant_option), and it now stresses the existing product_highlight and product_detail attributes for AI. In Google's testing with one brand, the conversational attributes it submitted were used in 50% of relevant product recommendations in AI Mode.

Extend the feed generator: up to 30 question_and_answer pairs per product (question and answer up to 1,000 characters each, 10,000 in total, with no prices, shipping, dates or company name), up to 100 product_detail specifications as section, attribute name and value, 2 to 100 product_highlight lines of up to 150 characters without promotional text, up to five document_link URLs of PDFs you hold the rights to, related_product for accessories and parts, and popularity_rank as a 0-100 rank against your own inventory. Source the answers from real customer questions, and keep the core attributes (price, availability, brand, GTIN) accurate first.
