Answer engines treat each vendor profile as an independently crawlable entity—they're not respecting parent-child hierarchies because they index for citation relevance, not curation. Test wrapping your CollectionPage in schema.org/WebSite + potentialAction (SearchAction) to establish your platform as the query interface, then use schema.org/mentions relationships (not hasPart) to signal aggregation without implying vendor subordination. If Perplexity still fragments, it's by design—you need to optimize for co-citation authority rather than structural markup.
