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 keywords
curl -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 keywords
curl -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 keywords
curl -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 1,000, KD < 40)

| Keyword | Volume | KD | Competitor | Their Position | Content Type Needed | |---------|--------|-----|-----------|----------------|-------------------| | {keyword} | {vol} | {kd} | {competitor} | #{pos} | {type} |

Medium Priority (Volume 200-1,000, KD < 50)

{Same table format}

Topic Cluster Gaps

Missing Clusters (Competitors have, you don't)

| Cluster Topic | Competitor Coverage | Est. Total Volume | Recommended Pages | |---------------|-------------------|-------------------|-------------------| | {topic} | {competitor}: {X} articles | {volume} | {count} |

Under-Covered Clusters (You have some, competitors have more)

| Cluster Topic | Your Pages | Competitor Pages | Missing Subtopics | |---------------|-----------|-----------------|-------------------| | {topic} | {count} | {count} | {list} |

Content Format Gaps

| Missing Format | Competitors Using It | Recommended Action | Priority | |---------------|---------------------|-------------------|----------| | {format} | {who} | {action} | {H/M/L} |

Buyer Journey Gaps

| Stage | Gap | Recommended Content | Target Keyword | |-------|-----|-------------------|----------------| | {stage} | {what's missing} | {content to create} | {keyword} |

AI/GEO Gaps

| Keyword | AI Overview? | You Cited? | Fix | |---------|-------------|-----------|-----| | {keyword} | Yes | No | {action} |

Prioritized Content Plan

| # | Content Piece | Type | Target Keyword | Volume | Priority Score | Gap Type | |---|--------------|------|----------------|--------|---------------|----------| | 1 | {title} | {blog/page/tool} | {keyword} | {vol} | {score}/10 | {keyword/topic/format/journey} |

Quick Wins (Low Effort, High Impact)

1. {Action} — {Why this is a quick win}
2. {Action} — {Why}
3. {Action} — {Why}

## 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.
