Prompt-Space

What Is Prompt-Space?

Prompt-space is the full set of questions a business's prospective customers might realistically type into an AI assistant about it, its category, or its city. It's a mapping exercise before it's anything else — you can't measure prompt coverage or share of AI voice without first defining the space those metrics are being measured against.

Most businesses have never written this list down. They know roughly what customers search for on Google, but haven't separated that from what customers might ask ChatGPT or Perplexity — which skews toward more conversational, evaluative, and comparative phrasing than a typed Google search does.

What a prompt-space is made of

A useful prompt-space usually spans several distinct query types, each behaving differently in AI systems.

Recommendation prompts sound like "best dermatologist in Koramangala" or "top-rated clinic near me" — the AI equivalent of a local pack search, and the type most dependent on review volume and rating.

Evaluation prompts are more specific to conversational AI than to traditional search: "is Sharma Skin Clinic good?" or "what do reviews for this place say?" These are queries a person types when they already have a specific business in mind and want a second opinion, and they hinge on how much legible review content exists about that exact business.

Service-specific prompts narrow to a particular offering — "where can I get a chemical peel in Indiranagar," "which clinic does laser hair removal near HSR Layout" — and depend on the GBP services section and structured service content actually naming that offering.

Informational prompts ask how something works or what it costs rather than where to get it — "how does a chemical peel work," "what does a chemical peel cost in Bengaluru" — and are answered mainly from FAQ content.

Credential prompts are increasingly common in regulated or trust-sensitive categories: "which dermatologist in Pune is board-certified," "experienced IVF specialist in Gurugram." These lean on accreditation listings and, where available, credential-specific schema.

Measuring coverage of the space

Once a prompt-space is mapped, prompt coverage is simply the percentage of it where the business shows up in at least one AI engine. A business covering 30 of a 50-prompt space sits at 60% coverage. The number matters less than what it reveals about which query types are covered and which aren't — a business might be strong on recommendation prompts and nearly invisible on informational ones, and that imbalance is the actual signal worth acting on.

Expanding coverage by query type

Different prompt types respond to different work, and treating them as one undifferentiated pile of "AEO content" tends to waste effort. Recommendation prompts move with review count and the pace of new reviews arriving. Service-specific prompts move with a complete GBP services section paired with structured content that names each service in plain language. Informational prompts move with genuine FAQ sections, ideally schema-marked. Credential prompts move with accreditation listings and, where relevant, credential schema on the website.

A clinic that pours all its effort into review generation while its FAQ page sits empty will see recommendation-prompt coverage climb and informational-prompt coverage stay flat — not because the AEO strategy failed, but because it was only aimed at one slice of the prompt-space.

India context

The Indian prompt-space for most local categories is still largely uncontested. Search volume for AI-native queries in India is younger than in the US, which means most competitors haven't mapped their own prompt-space yet, let alone built content against it. Businesses that do this mapping now — and build FAQ, service, and credential content deliberately against it — tend to hold an AI citation advantage that's genuinely durable, because the competitors catching up later are starting from the same near-zero baseline the early movers started from.

A worked example

A dermatology clinic in Pune mapped a prompt-space of just over 50 questions patients realistically ask across the five categories above. At the start of a structured AEO engagement it was cited for roughly 30 of them — 60% coverage. A nearby competitor, cited for 45 of the same 50, was effectively dominating the same prompt-space the first clinic was only half-covering, largely on the strength of a more complete services section and a much larger FAQ library.
