Prompt Research: Find Questions Buyers Ask AI
Use a repeatable prompt-research method to uncover, validate and prioritise the AI questions that shape B2B buying decisions.
What prompt research is — and what it is not
Prompt research finds and validates the natural-language questions buyers use with AI while making a category decision. Its output is a small, evidence-backed set of prompts with enough context to inform research, product, sales or content work.
It is not keyword research, which estimates search demand. It is not answer monitoring, which records what an assistant returns. It is not asking an LLM to invent plausible buyer questions. Each can support the work, but none alone demonstrates buyer behaviour.
For every prompt, record the buyer role, company type, constraint, category and decision stage. A change in any of these can change both the question and the answer. See how B2B buyers use AI to research and shortlist vendors for the wider buying context.
Start with the decision, buyer and evidence standard
Set a bounded research frame before collecting prompts:
For [buyer role] at [company type], understand the questions they ask AI when [triggering problem] so they can decide [decision].
For example: “For operations leaders at multi-site businesses, understand the questions they ask AI after a policy change so they can decide whether a workflow platform can support a consistent rollout.” This is a framing example, not buyer evidence.
Start with one buyer group, use case and decision. A pilot that attempts to cover every audience can produce a long list without clear provenance.
Use four labels throughout:
- Observed verbatim: wording from a consented interview, call note, survey response or search log.
- Paraphrased buyer evidence: a faithful summary where exact wording is unavailable.
- Assistant-suggested hypothesis: a variant or follow-up proposed by an AI tool.
- Unverified assumption: an idea with no supporting source.
Synthetic prompts can seed an interview discussion. They cannot be reported as questions buyers ask AI. Use B2B buyer research methods and a canvas to define the decision and evidence needed.
Collect prompt candidates from four evidence streams
Collect buyer evidence before testing assistants. Start with consented sales-call notes, win-loss interviews, support transcripts, on-site search and survey free text. Extract decision language: constraints, comparisons, proof requirements and implementation concerns. Remove personal, commercial and organisational identifiers before an item enters the ledger.
Interview recent customers and lost prospects. Ask which AI or search tool they used, what they asked first, what followed, which sources they opened, and whether an answer changed the shortlist. Ask for unaided recall before showing any candidate prompts.
Review public category discussions, reviews and comparison requests as hypothesis sources. Record the URL, date, speaker context and fit with the research frame. Public discussion is not proof that a target buyer group behaves in the same way.
Use AI assistants to generate variants and likely follow-ups, and label every output as a hypothesis. ChatGPT Search typically rewrites a query into targeted searches, so preserve the buyer’s visible wording alongside assistant outputs and cited evidence (OpenAI).
Capture the source, date, buyer context, exact wording and evidence strength when you find a candidate. B2B customer journey mapping research can help place each question in the decision journey.
Run the Prompt Evidence Ledger: a reproducible 60-minute pilot
Use the copyable Prompt Evidence Ledger below. It gives another researcher a route from a prioritised prompt back to its source.
| Evidence ID | Verbatim evidence | Source type | Buyer and context | Normalised prompt | Stage | Decision | Follow-up chain | Confidence | Stakes | Action owner |
|---|---|---|---|---|---|---|---|---|---|---|
| E-01 | “How can we tell whether staff understood the change?” | Consent-based research note | Operations lead; multi-site organisation; policy rollout | How can a multi-site business verify staff understanding after a policy change? | Proof and risk | Whether to adopt a workflow platform | What evidence should we collect? | 2 | Adoption evidence | Research lead |
Illustrative only: this fictional example is not observed buyer data.
Copy this blank worksheet for the pilot:
| Evidence ID | Verbatim evidence | Source type | Buyer and context | Normalised prompt | Stage | Decision | Follow-up chain | Confidence | Stakes | Action owner |
|---|---|---|---|---|---|---|---|---|---|---|
Run a 60-minute pilot in five steps:
- Extract 20 raw snippets without rewriting them. Redact names and sensitive detail.
- Normalise only enough to remove identifying information. Retain the constraint and decision.
- Cluster duplicates by underlying decision, while keeping original variants. Do not reduce them to a keyword.
- Test leading candidates in at least two relevant AI or AI-assisted search experiences. Use clean sessions where practical. Log the date, prompt, response, cited sources, suggested follow-ups and material differences.
- Open every cited source. OpenAI warns that search results and citations can be incomplete, outdated or incorrect; a citation is a lead to inspect, not proof (OpenAI).
The task is to assess the evidence around each prompt, not to declare an assistant “best”. Match the method to the uncertainty with UX research methods for choosing a study.
Categorise prompts by the buyer decision, not just funnel stage
A funnel label can obscure the decision behind a question. Use five practical groups:
- Problem framing: What is causing this issue?
- Category discovery: What types of solution exist?
- Comparison: Which option fits our requirements?
- Proof and risk: Can this work in our context, and what could fail?
- Purchase or implementation: What will it cost, require and change?
Add context tags for role, company size, geography, existing stack, budget and regulatory constraint. Capture the sequence: initial question, buyer-led or assistant-suggested follow-up, and the decision the chain unblocks.
Google describes AI Mode as supporting detailed questions, follow-up exploration and links to web sources (Google). Its documentation describes “query fan-out”, in which a complex question can generate related searches across subtopics (Google). Research the prompt chain where possible, rather than an isolated question.
Do not treat one assistant response as universal. Framing, context and available sources can affect it. Product research can turn recurring patterns into product questions.
Validate and prioritise the prompts worth acting on
Validate candidates through neutral recall. Ask: “Think back to how you researched this decision. What did you ask first, and what were you trying to establish?” Let participants describe their process before showing researcher-generated wording.
Score each candidate from 1 to 3:
| Factor | 1 | 2 | 3 |
|---|---|---|---|
| Evidence strength | Assumption or public hypothesis | Paraphrased or one observed source | Repeated observed wording or direct buyer recall |
| Decision proximity | General interest | Supports evaluation | Affects shortlist, approval or rollout |
| Audience fit | Adjacent audience | Partial match | Matches the research frame |
| Actionable gap | No clear action | Possible action | Clear research, product, sales or content action |
Add the four scores. The total does not establish truth; it makes the basis for the next action visible.
Prioritise prompts with observed evidence and a named decision. Where evidence is weak but stakes are high, use the question as an interview probe rather than a publishing brief. A practical pilot output is 15 evidence-tagged prompts, three priority decisions and one owner for each action. When recruiting, use UX research screeners and branching logic to find people with recent, relevant decision experience.
Turn the prompt map into ongoing buyer research
Give each priority prompt one next action: an interview-guide question, journey-map update, evidence gap, content brief or monitored AI-answer check. Repeat collection after a meaningful launch, category shift or recurring sales objection. Retain dates, sources and confidence labels so later claims about changing buyer behaviour can be audited.
A competing framework groups AI vendor-research questions into category, comparison, validation, pricing and implementation (Jeevan AI). That classification can be useful. Prompt research addresses an earlier question: is the wording supported by evidence, whose perspective does it represent, and which decision should it inform?
Before acting, check that you have:
- Preserved source-level provenance.
- Protected buyer privacy and confidential detail.
- Validated priority prompts with buyers.
- Inspected sources cited by AI-assisted answers.
- Assigned an owner to every next step.
Start with 20 snippets, build a 15-prompt pilot, then select three prompts for interviews, message testing or content work. Use research operations to make the ledger repeatable.
Frequently asked questions
What is prompt research?
Prompt research is a buyer-research method for finding, evidencing and prioritising the questions people ask AI while making a decision. It differs from keyword research and from monitoring assistant answers.
Can I use ChatGPT to find the prompts buyers ask?
Use it for hypotheses, variants and likely follow-ups, not as evidence of buyer behaviour. Validate candidates against buyer evidence and inspect cited sources when testing web-search answers.
How many prompts should a B2B team start with?
Start with about 15 evidence-tagged prompts. Choose three that have strong evidence, decision proximity, audience fit and a clear next action.
How do you validate questions buyers ask AI?
Use neutral interviews with recent buyers, consented research artefacts and source-level provenance. Ask participants to reconstruct their research process before comparing their recall with researcher-generated candidates.
