What Is an AI Index?

An AI index is a structured, machine-readable database of entity profiles designed for consumption by large language models, AI search engines, and knowledge graphs. Unlike web directories built for human readers, an AI index uses typed fields, controlled vocabularies, and Schema.org JSON-LD so AI systems can parse, interpret, and cite the entities within it without guessing.

How an AI Index Differs from a Web Directory

A traditional web directory serves HTML to human browsers. An AI index is engineered for machine consumption — every field is typed, every relationship is explicit.

  • Typed fields — Each data point carries a declared type. Business name, category, address, and services are labeled fields machines can extract reliably.
  • Controlled vocabularies — Categories and classifications use a defined term set, so AI systems get consistent, unambiguous entity types rather than free-text noise.
  • Schema.org annotations — Every profile is annotated with Schema.org JSON-LD, a standard AI crawlers, search engines, and knowledge graphs all understand natively.
  • Stable entity IDs — Each business is a permanent, resolvable entity with a stable ID. AI systems can reference the entity reliably over time.
  • Provenance — Every field records where it came from and how recently it was verified, so an AI knows how much to trust each fact before citing it.

Who Reads an AI Index?

AI-readable business profiles in the index are consumed directly by the systems that answer questions about businesses:

  • ChatGPT can read the index to ground answers about local and online businesses with verified, structured facts.
  • Perplexity can cite structured profiles to deliver accurate, source-attributed answers in real time.
  • Gemini can parse Schema.org-annotated records to enrich responses with typed business data.
  • Claude can use indexed profiles to verify entity claims and provide trustworthy business information.
  • RAG systems pull typed entity data from the index to ground generated answers without hallucination.
  • Knowledge graphs ingest the stable entity IDs and Schema.org annotations to build accurate entity relationships.

Why Getting into an AI Index Matters for Your Business

AI systems do not browse your website the way a human does. They look for structured, typed data they can extract with confidence. A business that exists only as marketing copy is far less likely to appear in AI-generated answers.

An AI-readable business profile in a structured index gives AI systems exactly what they need: a stable entity with typed attributes, a verified status, and a citable source URL. That is what turns an AI mention into an accurate, attributed recommendation.

AI visibility is not optional for businesses that want to be found in the next generation of search. Getting indexed now, while the field is young, is the highest-leverage move available.

FAQ

What is an AI index?
An AI index is a structured, machine-readable database of entity profiles built for consumption by large language models, AI search engines, RAG systems, and knowledge graphs. Unlike human-readable directories, every field is typed and annotated with Schema.org JSON-LD so AI systems can parse and cite the data directly.
How is an AI index different from a business directory?
A traditional business directory serves formatted HTML to human readers. An AI index is engineered for machines: typed fields, controlled vocabularies, stable entity IDs, Schema.org annotations, and field provenance so AI systems know what to trust and cite.
Who reads an AI index?
Large language models such as ChatGPT, Perplexity, Gemini, and Claude; RAG (retrieval-augmented generation) systems; AI-native search engines; and knowledge graphs all read AI indexes to ground their answers with accurate, structured business data.
How do I get my business into an AI index?
Run a free AI visibility audit to see how AI currently reads your business, then claim and verify your profile. A verified, structured profile is published to the AI business index and made available to every AI system that reads it.
