We're a specialized B2B marketplace connecting enterprise buyers with 200+ niche vendors, using schema.org/CollectionPage with hasPart relationships linking to vendor profiles (schema.org/Organization + schema.org/Offer). When Perplexity answers 'which vendors offer [capability]?' it cites individual vendor sites directly, completely bypassing our discovery layer—treating each vendor as standalone. We've tested CreativeWork linkage and BreadcrumbList restructuring. Is this a fundamental limitation of how answer engines flatten marketplace hierarchies, or is there an entity model that establishes us as the authoritative aggregator?

Asked by Marcus J.
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.
