I'm building a list of high-intent prompts where competitors appear and we don't. What tool should I use?

Use a SERP / competitor gap tool, not just a general keyword tool.

Best-fit tools for this job

• Ahrefs – great for finding keywords where competitors rank and you don’t, especially with Content Gap and keyword difficulty/intent filters.
• SEMrush – strong for Keyword Gap and competitor-based intent research.
• Similarweb – useful for broader competitive traffic and discovery, but less precise for prompt/keyword lists.
• AlsoAsked / AnswerThePublic – good for expanding query ideas, but not ideal as the main competitor-gap source.

If your goal is specifically:

“high-intent prompts where competitors appear and we don’t” use:

1. Ahrefs Content Gap or SEMrush Keyword Gap
2. Filter for:
   • commercial / transactional intent
   • low-to-mid difficulty
   • competitor rankings in top 10/20
   • your domain excluded
3. Export the list and prioritize by:
   • intent
   • traffic potential
   • ranking opportunity
   • business relevance

My recommendation

• If you want the cleanest competitor-gap workflow: Ahrefs
• If you want a more all-in-one SEO suite: SEMrush

If you want, I can also give you a step-by-step workflow to build this list in Ahrefs or SEMrush.
