# Content Gap Analysis

Identifies content opportunities by comparing your site against competitors and scoring the gaps worth closing first.

## Quick Start

```
Find content gaps between my site [URL] and [competitor URLs]
```

```
What content am I missing compared to my top 3 competitors?
```

## Skill Contract

**Expected output**: a prioritized gap brief plus the standard handoff summary for `memory/research/`.

- **Reads**: goals, market inputs, tool data, and prior strategy from [AGENTS.md](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/AGENTS.md) and the shared [State Model](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/references/state-model.md) when available.
- **Writes**: a user-facing analysis and reusable summary.
- **Promotes**: durable keyword priorities, competitor facts, and pending strategy decisions to `memory/hot-cache.md`, `memory/open-loops.md`, and `memory/research/`.
- **Primary next skill**: [seo-content-writer](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/build/seo-content-writer/SKILL.md) when the prioritized gap list is approved.

### Handoff Summary

> Emit the standard shape from [skill-contract.md §Handoff Summary Format](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/references/skill-contract.md).

## Data Sources

Optional integrations: ~~SEO tool, ~~search console, ~~analytics, ~~AI monitor. Without tools, ask for site URL, content inventory, competitor URLs, and business goals. See [CONNECTORS.md](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/CONNECTORS.md).

## Instructions

When a user requests content gap analysis:

1. **Define Analysis Scope** — confirm your site, competitors, topic focus, content types, audience, and business goals.
2. **Audit Your Existing Content** — map indexed pages, content types, topic clusters, winners, and weaknesses.
3. **Analyze Competitor Content** — compare content volume, traffic, type mix, topic coverage, and unique assets.
4. **Identify Keyword Gaps** — group gaps into High Priority, Quick Wins, and Long-term based on volume, difficulty, and relevance.
5. **Map Topic Gaps** — compare topic-cluster coverage and recommend pillar / cluster approaches for missing themes.
6. **Identify Content Format Gaps** — compare guides, tutorials, comparisons, case studies, tools, templates, video, and research.
7. **Analyze GEO / AI Gaps** — identify missing Q&A, definition, and comparison content that competitors get cited for.
8. **Map to Audience Journey** — compare Awareness, Consideration, Decision, and Retention coverage.
9. **Prioritize and Create Action Plan** — deliver an Executive Summary, Prioritized Gap List (Quick Wins / Strategic Builds / Long-term), Content Calendar, and Success Metrics.

> **Reference**: See [references/analysis-templates.md](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/research/content-gap-analysis/references/analysis-templates.md) for the compact templates used in each step.

## Example

See [references/example-report.md](https://github.com/aaron-he-zhu/seo-geo-Codex-skills/blob/main/research/content-gap-analysis/references/example-report.md) for a full SaaS marketing sample.

## Advanced Analysis

### Competitive Cluster Comparison

```
Compare our topic cluster coverage for [topic] vs top 5 competitors
```

### Temporal Gap Analysis

```
What content have competitors published in the last 6 months that we haven't covered?
```

### Intent-Based Gaps

```
Find gaps in our [commercial/informational] intent content
```

## Tips for Success

Focus on actionable gaps, respect execution constraints, and include GEO opportunities instead of only traditional search gaps.

### Save Results

After delivering, offer to save `memory/research/content-gap-analysis/YYYY-MM-DD-<topic>.md` and promote durable conclusions to `memory/hot-cache.md`.
