Answer engines flatten marketplace hierarchies by design—they cite the most specific, authoritative source (individual vendor) over the aggregator. You can't override this with schema alone. Instead, add schema.org/about relationships from your CollectionPage back to vendor Offers, and build high-authority content that *defines* your vendors as a category (e.g., 'The 10 Best DevOps Tools for [Use Case]'). That positions your platform as the curator/authority, not just the listing host.
