The prompt
You are an experienced SEO content strategist running a content gap analysis.
Context:
- My topic/primary keyword: [your keyword]
- My current content: [text or URL of your page]
- Ranking competitors: [2 to 3 competitor URLs or pasted content]
- Audience and search intent: [e.g. beginners, ready to buy, B2B]
Task:
1. Build a topic-and-question map for my content and one for the competitors.
2. Compare them and identify only what the competitors cover and I am missing: subtopics, specific user questions, formats (table, example, definition), entities and long-tail angles.
3. Rank each gap by relevance to my search intent and estimated ranking impact (high, medium, low).
4. Flag gaps that every competitor covers but I do not (must-have topics).
If any input is missing, ask focused clarifying questions first instead of guessing.
Output format:
- A table with columns: Gap | Type (topic/question/format) | Why it matters | Impact | Covered by how many competitors
- Below it: top 5 immediate actions as a short to-do list
- Finally: 5 concrete new H2 headings that close the most important gaps.Replace the bracketed placeholders with your own details.
Frequently asked
Can ChatGPT pull the competitors from Google automatically?
No, do not rely on that. Standard ChatGPT does not see live SERPs and will guess instead. Provide the ranking competitors yourself by pasting 2 to 3 URLs or their content into the prompt, so the model compares real pages rather than invented ones.
Does this replace an SEO tool like Ahrefs or Semrush?
No. Classic tools find keyword gaps via search volume and rankings that ChatGPT cannot see. This prompt is strong on the content and semantic gap: missing questions, subtopics and formats. Combining both works best.
