Google Merchant Center adds AI-oriented product attributes in feed specs

Google updated Merchant Center feed documentation in November 2025 with optional AI-oriented supplemental attributes—use case summaries, compatibility notes, and sustainability facts intended to improve generative shopping answers and in-feed enrichment. The fields are advisory today but early partner tests tie them to Gemini card eligibility in select categories.

• Primary use case (short plain-language sentence per SKU)
• Compatibility highlights (devices, sizes, regions supported)
• Sustainability or materials facts where relevant to buyer questions
• Link to canonical FAQ URL on merchant domain

Google emphasizes parity: supplemental feed text must match visible PDP content and JSON-LD. Mismatches trigger disapproval or exclusion from AI-enhanced placements in pilot programs.

Electronics, home improvement, and apparel pilots appeared first in US and DE Merchant Center accounts with historical feed health above median.

Visora audit cross-checks new supplemental fields against PDP HTML and schema. Export a Merchant Center alignment pack after audit to update feeds without guessing which AI attributes are empty on hero SKUs.
