We're an e-commerce brand selling the same products across multiple vertical marketplaces (Amazon, our site, Shopify store). When Gemini or Claude answers product queries, it cites the marketplace listing instead of our DTC site—even though we have better margins and brand control there. Is there a way to use schema markup or entity signals to boost our owned-domain authority for product queries in AI overviews?

Asked by Jake M.
Use schema.org/Brand + schema.org/Product with explicit `sameAs` properties linking all versions to a canonical brand entity URI (your homepage), plus add `mainEntity` markup on your DTC product pages. But real talk: answer engines weight distribution, freshness, and user engagement over markup—if your DTC site has lower traffic/engagement than the marketplace, schema alone won't flip the citation. You need content and topical authority plays alongside the markup.
