Schema design for query pattern coverage. Express same claim in multiple lexical forms. Example: “AI consulting” + “artificial intelligence advisory” + “machine learning consultancy” for same service. Prevents query brittleness (only visible to one phrasing). Implement through: schema.org additionalType, Wikidata multiple labels, directory category coverage. Audit by reviewing competitor query patterns. Not keyword stuffing — structured semantic variety. Use Variety Audit Protocol to identify coverage gaps. Balance: enough variety to match patterns, not so much it creates ambiguity.
