What is Entity Disambiguation?

Entity disambiguation is the practice of providing enough structured signals that search engines and AI systems can uniquely identify who or what you are — distinguishing you from every other entity with a similar name. For a person, this means establishing a specific combination of name, company, location, expertise, and cross-platform presence that is unmistakably yours.

The tools for disambiguation include: Person and Organization schema with sameAs links to authoritative profiles (LinkedIn, GitHub, Crunchbase), an llms.txt file that explicitly defines your entity for AI crawlers, consistent NAP (Name, Address, Phone) information across your site and external directories, and a Knowledge Panel strategy that connects your website to Google's Knowledge Graph.

AI search engines rely heavily on entity disambiguation when deciding what to cite. If Perplexity encounters three consultants named 'Aryan' who work in AI, it needs structured signals to determine which one is the expert in AI automation for healthcare in Bengaluru. The more unambiguous your entity signals, the more confidently an AI engine can cite you — and the less likely it is to confuse you with someone else or hallucinate incorrect details about you.
