How to Find Question Keywords for AI Search

How do you find question keywords for AI search?

Start with a seed topic, then collect the full-sentence questions people ask around it from Google’s People Also Ask, autocomplete, AnswerThePublic, Reddit, and Quora. Filter for questions with buyer intent, group them by theme, and write one clear, answer-first post per question. AI engines pull answers from pages that address a specific question directly.

Question keywords are the longer, conversational phrases people type — or speak — when they want an answer, not a list of links. “What’s the best CRM for a two-person law firm” instead of “law firm CRM.” These are the queries that AI search tools like ChatGPT and Google’s AI answers are built to satisfy, which makes them worth targeting deliberately.

Why this matters for a small business

Search is splitting into two modes, and questions dominate the newer one. Backlinko’s analysis of 306 million keywords found that 14.1% of Google searches are already phrased as questions, and that share climbs sharply in AI contexts. Pew Research Center found that Google shows an AI summary for 53% of searches with ten or more words, versus just 8% of one- or two-word searches — and long searches are almost always questions.

The audience is real. OpenAI reported ChatGPT reached about 900 million weekly active users in early 2026, many of them asking full-sentence questions a small business could answer. If your content matches the exact question a buyer asks an AI tool, you have a shot at being the source it cites — and question keywords are how you find those questions.

“Half our new leads now say they ‘saw us mentioned when they asked ChatGPT.’ We didn’t do anything magic — we just wrote posts that answered the exact questions they were asking.” — Tom Whitfield, owner of an IT support company (illustrative).

How to find question keywords for AI search

1. Start with seed topics and let Google autocomplete run

List the core topics you sell. Type each into Google and add “how,” “what,” “why,” “is,” and “best” in front — autocomplete finishes the real questions people search. Do the same in the ChatGPT and Gemini text boxes to see how the same topic gets phrased conversationally. Write down every full question that fits your business.

2. Mine People Also Ask and question-mapping tools

Search a seed keyword and expand Google’s People Also Ask box; each click reveals more questions. Free tools like AnswerThePublic and AlsoAsked map the same question data into a visual tree. This is the fastest way to go from one topic to thirty real questions — see how to turn People Also Ask into blog posts for the deeper workflow.

3. Read where your customers actually ask

Reddit, Quora, and niche forums are full of the unpolished, full-sentence questions people ask before they buy. Search your topic on each and note the recurring questions — especially the ones with lots of replies. These often reveal phrasing and concerns that keyword tools miss entirely, and they’re exactly the questions people paste into AI chats.

4. Filter for intent, not just curiosity

Not every question is worth a post. Favor questions where the asker is close to hiring or buying — “how much does X cost,” “is X worth it,” “best X for Y” — over pure trivia. See commercial vs informational keywords for how to read that intent. A shorter list of high-intent questions beats a huge list of idle ones.

5. Group questions and write one answer-first post each

Cluster related questions by intent, pick the lead question for each cluster, and write a post that answers it in the first 40-to-55 words, with follow-up questions as H2 sections. AI engines and Google both favor pages that answer a specific question directly and completely. Clear structure and a direct answer up top do more for AI visibility than any technical trick.

6. Check whether you’re actually getting mentioned

After publishing, test it: ask ChatGPT and Gemini the questions you targeted and see whether your business comes up. AI answers are non-deterministic — the same prompt can name different sources each time — so look at whether you’re mentioned across repeated checks, not at a single “rank.” Re-check periodically, especially after you add or update posts.

What to know about AI search and honesty

A few things are worth being clear-eyed about, because a lot of AI-SEO advice overpromises.

There is no stable “AI rank.” Ask the same question twice and the sources and order can change. So measure whether you’re mentioned, and how that trends over repeated checks — not a single position. Anyone selling you a fixed AI ranking is measuring noise.

You also can’t scrape the consumer ChatGPT app to track this — there’s no legitimate API for it. Reputable measurement uses each vendor’s official, web-grounded answers. That’s the approach ScoutRival takes: its AI-visibility check runs your questions through two engines — ChatGPT (web-grounded) and Google Gemini (a “model-memory” probe) — on demand, whenever you choose to re-check, not on some automatic schedule. Full disclosure: ScoutRival is our tool. Plans start free and run $29, $89, and $149 a month; it’s built for service businesses with no marketing team, and it’s not a CRM or a post scheduler.

Finally, skip the myths. Adding an llms.txt file does not improve your AI visibility — no major AI system is documented to read it. What actually helps is boringly familiar: clear, question-shaped content that answers the query directly.
