AI-Ready Product Feeds: Merchant Center Attributes for AI Mode, Gemini and Shopping Agents
Abhishek Dwivedi
Team Lead, SEO
AI-powered shopping experiences can only represent products accurately when the underlying data is complete, consistent and current. Merchant Center feeds, product-page structured data, images, video, inventory and policies form a shared evidence layer for AI Mode, Gemini and other shopping experiences. This guide turns Google’s specifications into an operational feed-audit process.
Start with stable identity and offer data
Every item needs a stable ID and a landing page that resolves to the same product. Supply accurate title, description, image link, price, availability and condition, plus brand, GTIN or MPN when applicable. Use item group IDs to connect variants without collapsing distinct sizes, colours or configurations into one offer.
Keep price, sale price, currency and availability synchronized with the landing page. Enable structured data and automatic updates where appropriate, but treat them as safeguards rather than substitutes for a reliable primary data source.
Use product details for specifications AI can compare
Google’s product detail attribute lets merchants provide structured technical specifications that may help customers discover products across AI-driven surfaces such as AI Mode. Organise details into clear sections and use consistent attribute names and values across a category.
Prioritise facts that change purchase decisions: dimensions, material, capacity, compatibility, fit, care, included components, warranty and operating requirements. Do not duplicate promotional copy or add unverifiable superlatives.
Model variants, shipping and loyalty precisely
Use the correct colour, size, material, pattern and variant attributes, and keep variant URLs and images aligned. Google added new 2026 capabilities including variant-related updates, product-level shipping fields and loyalty shipping labels. Implement only attributes supported for the target country and programme.
Shipping cutoff, handling time, minimum order value and return information should match checkout. For local inventory, maintain store codes, availability and price with the required update frequency.
Improve image and video evidence
Use high-resolution primary images with a clean view of the product, then add alternate angles, scale, details and lifestyle context. Google’s 2026 specification introduced the optional video link attribute and announced higher minimum image-resolution requirements beginning in 2027. Audit small legacy images now instead of waiting for enforcement.
Label AI-generated titles, descriptions or images using the attributes and metadata Google requires. Synthetic media should not misrepresent product colour, dimensions, included items or real-world performance.
Create a feed-quality operating system
Monitor disapprovals, warnings, freshness, attribute completeness, landing-page mismatches and sudden changes by source system. Assign category owners for product details and technical naming. Sample live products weekly and compare the feed, structured data, page, checkout and warehouse record.
Google has announced Merchant Center insights for visibility across AI Mode, AI Overviews and Gemini, including product-term and attribute insights. Use these reports when available to find missing specifications, then validate changes against conversion quality and returns.

Google's October 2026 AI Content Guidance: SEO and E-E-A-T Checklist
Google updated its guidance on generative AI content on 1 October 2026, aligning the documentation more closely with its Search Quality Rater Guidelines. The update does not create a special ranking system for AI-written pages. It sharpens the standard that matters: content should serve a clear audience, demonstrate real expertise and make factual claims easy to verify. For Indian marketing teams using AI at scale, the operational question is no longer whether AI may be used. It is whether every published page adds original value, accountable authorship and dependable evidence.
