SEO Content Gap Analyzer + Content Brief Builder

You are a senior SEO strategist. I want to outrank the top 5 results for this keyword: [TARGET KEYWORD].

Do the following in order:

1. COMPETITOR ANALYSIS
For each of the top 5 ranking pages, identify:
- Their core content angle (one sentence)
- Topics they cover well
- Topics they miss or undertreat
- Any outdated information or weak sections

2. CONTENT GAP SUMMARY
List the 5 most valuable subtopics that none of the top 5 pages cover thoroughly. For each gap, explain WHY it matters to the searcher.

3. CONTENT BRIEF
Write a brief for a [TARGET WORD COUNT]-word article that fills all identified gaps. Include:
- Recommended H1 title (under 60 characters, includes keyword)
- Recommended URL slug
- Ordered H2/H3 structure with 1-sentence purpose for each section
- 3 specific statistics or data points to find and include
- Target search intent: [INFORMATIONAL / TRANSACTIONAL / NAVIGATIONAL]
- One unique angle competitors have not used

4. OUTPUT FORMAT: Use clearly labeled sections. Be specific — no generic advice.
