Why is my brand invisible in Google AI Overviews shopping comparisons?
Google AI Overviews constructs product comparisons by cross-referencing Google Merchant Center feeds with on-page Schema.org Product microdata. Brands become invisible when there is price disparity, mismatched GTIN identifiers, or when Google's Shopping Graph cannot verify direct checkout capability on the destination URL.
Google Merchant Center data indicates that stores with synchronized on-page schema and Merchant Center feeds appear in AI Overviews 3.4x more frequently than stores with unverified or disconnected microdata.
Google's AI Mode uses a strict entity consensus filter. If the price in Google Merchant Center does not match the static `@type: Offer` price on the storefront down to the cent and currency ISO, the entity is penalized as unreliable.
