Schema markup generators - Merkle, Rank Math, Schema App, and Google's own Rich Results Test - are the implementation entry point for AEO practitioners who need to create valid JSON-LD without writing it from scratch. Understanding which tool to use for each use case, what generators can and cannot do, and how to validate generated schema, is the practical foundation of implementing the schema that powers AI citation eligibility.
