We're a vertical marketplace for [niche industry] and when answer engines cite our platform in product/service discovery queries, they sometimes attribute to our domain, sometimes to individual seller profiles within our marketplace, and sometimes to neither—just aggregating data without attribution. We've marked up our marketplace with schema.org/CollectionPage + hasPart relationships linking to individual listings with schema.org/Offer, but answer engines seem to treat each seller listing as its own entity. Should we be restructuring our schema to establish a clearer parent-child entity hierarchy, or is this a fundamental limitation of how LLMs crawl and parse marketplace structures?
Asked by Priya N.
This is a schema parsing gap—most LLMs don't fully traverse hasPart/isPartOf relationships the way Google's Knowledge Graph does. Your best play is adding an explicit Organization entity at the marketplace level with schema.org/aggregateOffer or schema.org/AggregateRating, plus consistent brand entity markup (schema.org/BrandName + logo) on every aggregated result. Also ensure your marketplace robots.txt and sitemap clearly signal crawlability for both parent and child pages; some answer engines deprioritize crawling nested marketplace structures.
