Google's product listing surface, fed by Merchant Center feeds.
Google Shopping displays product listings across Google Search, Images and the dedicated Shopping tab. Shopify feeds products via the Google & YouTube channel or via a Merchant Center feed. Feed rules are unforgiving: missing barcodes, mismatched prices between feed and landing page, or compare-at values that violate the 30-day rule trigger disapprovals within hours. Every catalog SEO change that affects title, description, price, availability or images needs a feed check.
