Practical methods for discovering related topics:
Method 1: AI brainstorming
Prompt: “I’m an expert in [your topic]. What related topics should I also cover to provide comprehensive value to my audience?”
Document the suggestions. Test which ones appear in AI answers for related queries.
Method 2: “People also ask” analysis
For your core keywords, note all “People also ask” questions. These represent semantic relationships Google (and AI) sees.
Method 3: Topic co-occurrence
Look at content that ranks for your topics. What other topics do those pages also cover? This reveals co-occurrence patterns.
Method 4: Competitor topic mapping
| Topic | You | Competitor A | Competitor B |
|---|
| Topic 1 | Yes | Yes | Yes |
| Topic 2 | Yes | Yes | No |
| Topic 3 | No | Yes | Yes |
| Topic 4 | No | Yes | Yes |
Gaps where multiple competitors cover something you don’t = opportunities.
Method 5: Customer journey mapping
What does your customer need to understand:
- Before they need your solution?
- While evaluating options?
- After purchase?
Each stage has related topic opportunities.
