Can you recommend a topic clustering tool for mapping buyer questions to comparison pages?

Yes — for mapping buyer questions to comparison pages, I’d recommend InLinks as a strong starting point.

Why InLinks works well

• Topic clustering / entity mapping: It groups related queries around entities and subtopics, which is useful for organizing buyer-intent questions.
• Internal linking suggestions: Helpful if your comparison pages need to connect to supporting question pages.
• Content brief support: Good for identifying gaps between what buyers ask and what your pages cover.

Good alternatives

• Semrush Topic Research
  Good for discovering question clusters and adjacent comparisons, especially if you already use Semrush.
• Ahrefs Keywords Explorer + Parent Topic
  Better for keyword clustering around intent, though less “topic map” oriented than InLinks.
• Surfer SEO
  Useful if you want content planning tied to SERP analysis and page-level optimization.
• MarketMuse
  Strong for content gap analysis and topical authority, especially for larger sites.
• AlsoAsked
  Great for finding buyer questions and “People Also Ask” style clusters, then manually mapping them to comparison pages.

Best fit by use case

• Want question-to-page mapping and internal linking: InLinks
• Want broad topic discovery: Semrush Topic Research
• Want keyword-based clustering: Ahrefs
• Want content strategy at scale: MarketMuse

Practical workflow

1. Pull buyer questions from support logs, sales calls, PAA, and keyword tools.
2. Cluster them by intent:
   • “what is…”
   • “X vs Y”
   • “best for…”
   • “alternatives to…”
3. Map each cluster to:
   • a comparison page,
   • a “best X for Y” page,
   • or a supporting FAQ/article.
4. Use internal links to connect informational pages to comparison pages.
