You landed a valuable podcast guest — but you spent 15 minutes Googling their name for questions. Result: a predictable interview where they repeat the same talking points, and listeners tune out halfway. Topic mining is a structured research process to find genuinely fresh angles — questions the guest actually looks forward to answering.
What is topic mining?
Topic mining is a structured review of a guest's public footprint — published content, past interviews, social media commentary, books or articles they share — to identify:
- Topics they care about but rarely get asked about
- Views they hold that go against the mainstream
- Personal experiences that have not been explored on air
- Interesting intersections between their expertise and your podcast's themes
Four-layer topic mining template
Layer 1 — Content audit (30 min)
List all content the guest has published in the past 12 months:
- Podcasts and interviews they appeared in → note which questions were already asked
- LinkedIn or blog posts → identify their most recurring themes
- Long Twitter/X threads → spot the opinions they argue most passionately
Goal: build a "already covered" list to actively avoid repetition.
Layer 2 — Tension mapping (20 min)
Find where the guest's views diverge from mainstream thinking in their field. These are usually your best questions — they have clear opinions ready and will answer with genuine energy.
Layer 3 — Intersection finding (15 min)
Find the overlap between the guest's expertise and trends currently hot in your niche. Example: guest is a branding expert + AI is trending → ask "Can AI genuinely create brand identity, or is it just pattern matching?"
Layer 4 — Draft 10, pick 5
Draft 10 questions from the above layers → cut generic ones → select 5 most unique as the backbone of your interview. Keep the remaining 5 as backup if the conversation takes a different turn.

Fit this into your podcast workflow
Do topic mining 3–5 days before the interview — early enough to craft thoughtful questions, close enough that the context stays fresh. See also: podcast guest pre-interview prep template and podcast deep dive interview prep.
