Prompt Research for AI Search: Where to Find the Questions Worth Tracking

Keyword research has twenty years of tooling behind it. Prompt research is newer, and most teams handle it by brainstorming in a meeting and pasting the results into a tracker. That produces prompts that sound right to the marketing team and don't match how buyers talk to assistants.

Good prompt research has two halves: finding candidate questions from real sources, then filtering them with demand and difficulty data. Here are the sources we'd use, roughly from cheapest to most effort.

1. Your own customer conversations

The Promptwatch Academy's guide to choosing prompts starts here, and it's the right place. Support tickets, chat logs, FAQs, and notes from sales and customer success are the closest thing you have to the real phrasing of buyer questions.

Look for repeated questions and the constraints people attach to them. "Which tool works with HubSpot and has a Dutch interface?" is a prompt. "CRM integrations" is a keyword.

2. Public forums and communities

AI models learn from public discussion, and forums show how people phrase intent when nobody's selling to them. Search Reddit, X, and niche communities for your category and read the question threads. Each recurring question is a potential prompt.

This source is also useful later. Promptwatch tracks which Reddit threads AI answers cite, so the threads you research now can become places to show up.

3. Reviews of you and your competitors

Trustpilot, G2, and app store reviews show the words people use for features, pain points, and comparisons. Phrases like "better than" and "alternative to" often mirror how assistants frame recommendation prompts. Competitor reviews are especially useful because they show what buyers wish the other product did.

4. Google Search Console

Your Search Console queries are searches real people typed that led to your site. They're not prompts, but they're good raw material. Promptwatch can pull Search Console queries into its Prompt Explorer as a starting point, so you don't have to export and rewrite them by hand.

Treat these as topics. Rewrite each one as the full question a buyer would ask an assistant.

5. People Also Ask and ranking keywords

Prompt Explorer also suggests prompts from your ranking keywords, from People Also Ask, from manual searches, and from any page on your website. People Also Ask is useful because the questions are already phrased as questions. Generating prompts from your own pages helps you check whether the questions your content answers are the ones people ask.

6. AI autocomplete

Promptwatch's Prompt Volumes view includes an AI autocomplete. You start typing ("best crm for") and it suggests completions with volume next to them. It's the closest equivalent to keyword suggestion tools, built for conversational queries, and it's a fast way to find the high-demand variants of a question you already know matters.

7. Competitor gaps in your own tracking

Once your first monitors are running, the most valuable source is your own data. Look for prompts where competitors are visible and you aren't. Promptwatch's prompt suggestions draw on competitor gap analysis for exactly this reason. These gaps are the prompts most likely to pay off, because you already know the answer includes brands like yours.

Filtering what you found

A good research session produces far more candidates than you should track. Filter in this order:

Volume. Promptwatch estimates prompt volume from attached keywords, weighting AI search demand most heavily, and shows it as a band of one to five bars. No volume is a reason to drop a prompt unless it's a competitor comparison or brand accuracy check.
Difficulty. Based on the past 30 days, it blends keyword competition with the authority of sources AI already cites for the prompt. Low difficulty with decent volume goes to the top.
Intent. Tag each prompt as branded, informational, navigational, commercial, or transactional. Commercial and transactional prompts usually deserve priority even at lower volume.

Then keep the list small. Promptwatch recommends starting with 15 to 30 prompts per monitor or market and expanding from what moves the needle.

Keeping the list alive

Prompt research isn't a one-off task. The Academy recommends adding emerging topics from newsletters, analyst reports, and social posts early, before competitors build visibility around them. A quarterly pass lines up with how often keyword volume data refreshes.

If you want the research sources and the filtering on the same screen, Promptwatch is the tool we'd use. Essential is $95/mo for 50 prompts with a 7-day trial. Other options are on our tool rankings.
