Top 5 Schema Types for AI Search in India

Why schema matters more for AI search than for classic SEO

Search engines have always been able to infer meaning from prose, even messy prose, well enough to rank a page. AI systems generating an answer don't have that luxury of time — they extract from whatever's declared clearly, and schema is the mechanism for declaring it. A clinic that writes "we're a leading dermatology practice" in flowing prose and a clinic that marks up the exact same fact as structured LocalBusiness data are saying the same thing to a human reader and very different things to an AI system. This list covers the five schema types that matter most for Indian local businesses trying to earn AI Overview and AI-chatbot citations, in roughly the order they're worth implementing, and it sits alongside the broader structured data glossary entry for anyone starting from zero.

1. FAQPage schema

FAQPage schema turns FAQ content into structured question-answer pairs an AI system can extract directly rather than interpret from surrounding paragraphs. It's arguably the single highest-impact schema type for AI Overview citations, because the format matches almost exactly how AI Overviews present answers back to a user — a question, then a direct response. A dental clinic with a properly marked-up FAQ answering "how many sessions does root canal take" can earn a citation for that specific query without needing to rank first for the broader keyword. The technical shape is a FAQPage type with a mainEntity array of Question entities, each carrying an acceptedAnswer. FAQPage schema covers the field-level setup, and Google's Rich Results Test is the way to confirm it validates before assuming it's working.

2. LocalBusiness schema

LocalBusiness schema, and its more specific subtypes like MedicalClinic, Restaurant, Hotel or RealEstateAgent, declares the business entity itself in a machine-readable form — what it is, where it is, how to reach it. Every other AI citation signal effectively sits on top of this one, because an AI system that can't confidently establish what the business even is has nowhere to hang the rest of the information. This is also the schema type most commonly missing from Indian business websites entirely; a clinic with no schema forces an AI system to infer entity data from HTML prose, with more room for error than a direct read. The fields that matter are the specific @type, name, a proper PostalAddress, telephone, geo coordinates, openingHoursSpecification, and sameAs links back to other verified profiles. Local business schema covers implementation, and the LocalBusiness schema glossary entry has the field reference.

3. HowTo schema

HowTo schema marks up step-by-step content, declaring each step as its own HowToStep entity so an AI system can extract a specific step rather than the whole guide undifferentiated. This is the schema type behind procedural query citations — "how do I do X" — which show up constantly in healthcare, education, BFSI and real estate. A real estate agency publishing "how to buy a flat as a first-time buyer in India" with proper HowTo markup gives an AI system numbered steps it can quote directly in response to a first-time-buyer query, rather than a vague paraphrase of a long article. HowTo schema has the setup detail.

4. Speakable schema

Speakable schema marks a specific section of a page, usually a short direct-answer passage, as the content best suited for voice and audio extraction. Its relevance is growing rather than established, since voice assistants and some AI systems increasingly favour a concise spoken-style answer over a long block of text. For a business with Hindi-language content aimed at voice queries like "mere paas best doctor kaun hai," marking the Hindi answer capsule with Speakable schema is a forward-looking move — the payoff depends on how fast vernacular voice AI adoption actually grows, which isn't something any vendor can promise a timeline for. Speakable schema covers the setup, and vernacular search covers the broader Hindi and regional-language context this schema type sits inside.

5. DefinedTerm schema

DefinedTerm schema marks up glossary and definition content, declaring each term as a structured entity inside a DefinedTermSet. It's the schema type behind "what is X" knowledge queries, and it matters most for businesses in fields with real jargon to explain — healthcare procedures, financial products, real estate terms, legal processes. A fintech company publishing a glossary of investment terms with DefinedTerm schema gives an AI system a clean source to cite when someone asks what a specific term means, which builds brand association alongside the citation itself. DefinedTerm schema has the setup, and Angryturtle's own local SEO glossary is a working example built on this schema type across more than a hundred terms.

Implementation order, not a checklist

For most Indian local businesses, LocalBusiness schema comes first because it's the entity foundation everything else depends on. FAQPage schema comes next because it's the single highest-impact type for AI Overview citations specifically. HowTo schema follows for any business with genuine procedural content worth marking up. Review-related structured data, covered separately in review schema markup, fits in alongside these rather than after them. Speakable and DefinedTerm are worth adding once the foundation is solid, not before — there's limited value in voice-optimising a page whose basic entity data isn't declared yet.

What schema doesn't do

Schema makes content more machine-readable and raises the odds of citation. It doesn't guarantee one. Review signal, entity authority built through consistent presence across GBP and Indian directories, and the actual quality of the content still factor in alongside the markup — schema is necessary, not sufficient. Entity authority and structured data for AI answers cover how these pieces fit together, and signals AI engines actually read covers the broader picture beyond schema alone.

FAQ

Can one page have multiple schema types? Yes. A service page can carry LocalBusiness schema for entity declaration, FAQPage schema for its FAQ section, and HowTo schema for a process section, all at once. The types don't conflict with each other because they address different query types.

Does schema guarantee AI citations? No. Schema makes content more machine-readable and increases the probability of citation. Review count, entity authority and content quality all factor in alongside schema, and none of these are things schema markup alone controls.

Which schema type should a business without much technical resource start with? LocalBusiness schema first, since it's the foundation, followed by FAQPage schema on whichever pages already have a genuine FAQ section. Both are implementable with a WordPress SEO plugin or a Google Tag Manager custom HTML block without custom development.
