hreflang doesn't signal to LLMs the way it does to Google's crawler—answer engines treat subdomains as separate entities. Build a parent Organization entity with schema.org/location + address markup for each regional branch, then link each subdomain's schema to that parent org via schema.org/parentOrganization. Also add geo-specific schema.org/GeoShape or schema.org/Country metadata to your Product schema on each regional site so LLMs can semantically associate products with regions, not just rely on domain structure.
