Quick answer: AEO prompt research finds the full questions buyers ask AI assistants before they choose a product or service. Collect questions from sales calls, support tickets, reviews, Search Console queries, People Also Ask, AlsoAsked and communities like Reddit, rewrite them as natural prompts, group them by intent (best for, versus, alternatives, price, how-to, local), and prioritise 20 to 100 that are closest to revenue.
Keyword research gives you short phrases and search volumes. Prompt research gives you the long, specific questions people now type into ChatGPT or say to Gemini: “Which CRM is easiest for a 10-person team that sells on WhatsApp and needs GST invoices?” Those questions decide which brands get named.
Key takeaways
- The best prompts come from your own customers’ words.
- Write prompts as full questions with context: budget, team size, location, use case.
- Cover every buying stage, weighted toward decision questions.
- Keep the set stable so monthly tracking is comparable.
- 20 to 100 prompts is the practical range for most businesses.

How do you build a prompt set?
- Collect raw questions from the sources above into one sheet.
- Rewrite as natural prompts with the context buyers add: budget, size, location, industry.
- Remove duplicates and merge near-identical questions.
- Tag each prompt by type, stage, product line and market.
- Score priority by closeness to revenue and how often you hear it.
- Pick 20 to 100 for tracking; keep the rest as a content backlog.
- Freeze the wording so month-to-month results compare fairly.
How do you use the prompt set?
- Test it across engines for your AEO audit baseline.
- Map each prompt to the page that should answer it, and create pages for gaps.
- Write those pages answer-first.
- Track it monthly in a tool from the AEO tool stack.

Frequently asked questions
How is prompt research different from keyword research?
Keyword research focuses on short phrases and volumes. Prompt research focuses on full questions with context, which is how people talk to AI assistants. Both are useful together.
Is there search volume data for AI prompts?
Not in the same way as keywords. Some AI visibility tools estimate prompt popularity, but your own customer questions are the most reliable guide.
How often should the prompt set change?
Keep the tracked core stable for comparison, and review it every quarter to add new products or questions.
Should prompts include brand names?
Include some, such as “is [your brand] good for X” and “[competitor] alternatives”, but most prompts should be unbranded to show whether you are recommended without being asked for.
