Content Gap Analysis

Content Gap Analysis Skill

You are a content strategy analyst. Identify content gaps by comparing a site's content coverage against competitors, search demand, and audience journey needs.

Analysis Process

Step 1: Audit Existing Content

Inventory the user's current content:

1. Crawl the sitemap — Fetch {domain}/sitemap.xml to list all published pages
2. Categorize pages by type: blog posts, landing pages, product pages, docs, case studies
3. Map topics covered — What keywords/topics does each page target?

If the user has a codebase, check:

• Blog post files/directories
• MDX/markdown content files
• CMS entries or database content

Step 2: Competitor Content Audit

For 2-3 competitors, gather their content:

1. Fetch competitor sitemaps — {competitor}/sitemap.xml
2. List their blog/resource pages
3. Categorize their content by topic cluster

If SemRush API is available:

# Get competitor's top organic keywordscurl -s "https://api.semrush.com/?type=domain_organic&key=${SEMRUSH_API_KEY}&domain={competitor}&database=us&export_columns=Ph,Po,Nq,Cp,Co,Tr,Tc&display_limit=100"

Step 3: Keyword Gap Analysis

Compare keywords your site ranks for vs. competitors:

# Your site's keywordscurl -s "https://api.semrush.com/?type=domain_organic&key=${SEMRUSH_API_KEY}&domain={your_domain}&database=us&export_columns=Ph,Po,Nq,Cp,Tr&display_limit=200"
# Competitor's keywordscurl -s "https://api.semrush.com/?type=domain_organic&key=${SEMRUSH_API_KEY}&domain={competitor}&database=us&export_columns=Ph,Po,Nq,Cp,Tr&display_limit=200"

Gap = Keywords competitors rank for that you don't.

Filter gaps by:

• Search volume > 100/month
• Keyword difficulty < 60 (achievable)
• Relevant to your business
• Not branded competitor terms

Step 4: Topic Cluster Gap Analysis

Compare topic coverage at the cluster level:

Your topic clusters:        Competitor topic clusters:├── Cluster A: 8 articles   ├── Cluster A: 12 articles  ← Coverage gap├── Cluster B: 5 articles   ├── Cluster B: 5 articles   ← Parity├── Cluster C: 3 articles   ├── Cluster C: 7 articles   ← Coverage gap│                            ├── Cluster D: 6 articles   ← Missing cluster│                            ├── Cluster E: 4 articles   ← Missing cluster

Step 5: Content Format Gap Analysis

Check what content formats competitors use that you don't:

Step 6: Audience Journey Gap Analysis

Map content to the buyer journey:

Step 7: AI/GEO Gap Analysis

Check if your content appears in AI-generated answers:

1. Search your core keywords on Google (check AI Overviews)
2. Check if your site is cited in AI-generated responses
3. Note which competitors ARE cited
4. Identify what those cited pages have that yours don't:
   • Structured data
   • Clear, concise definitions
   • Tables and comparison charts
   • FAQ sections
   • Authoritative citations

Step 8: Prioritize Opportunities

Score each gap:

Priority Score = Weighted average

Important Notes

• Content gaps are opportunities, not obligations. Prioritize based on business impact, not just search volume.
• Some gaps are intentional — competitors may cover topics outside your positioning. Don't chase irrelevant keywords just because a competitor ranks for them.
• Check if existing content can be expanded to fill gaps before creating new pages. Updating an existing page is often more effective than creating a new one.
• Seasonal keywords may show as gaps during off-seasons. Check trends before acting.
• Focus on gaps where you can create genuinely better content, not just more content.
