+
+## Data Sources
+
+> **Note:** All integrations are optional. This skill works without any API keys — users provide data manually when no tools are connected.
+
+> See [CONNECTORS.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/CONNECTORS.md) for tool category placeholders.
+
+**With ~~SEO tool + ~~search console connected:**
+Automatically pull historical search volume data, keyword difficulty scores, SERP analysis, current rankings from ~~search console, and competitor keyword overlap. The skill will fetch seed keyword metrics, related keyword suggestions, and search trend data.
+
+**With manual data only:**
+Ask the user to provide:
+1. Seed keywords or topic description
+2. Target audience and geographic location
+3. Business goals (traffic, leads, sales)
+4. Current domain authority (if known) or site age
+5. Any known keyword performance data or search volume estimates
+
+Proceed with the full analysis using provided data. Note in the output which metrics are from automated collection vs. user-provided data.
+
+## Instructions
+
+When a user requests keyword research:
+
+At the start of each phase, announce: **[Phase X/8: Name]** so the user can track progress.
+
+### Phase 1/8: Scope
+
+   Ask clarifying questions if not provided:
+   - What is your product/service/topic?
+   - Who is your target audience?
+   - What is your business goal? (traffic, leads, sales)
+   - What is your current domain authority? (new site, established, etc.)
+   - Any specific geographic targeting?
+   - Preferred language?
+
+### Phase 2/8: Discover
+
+   Start with:
+   - Core product/service terms
+   - Problem-focused keywords (what issues do you solve?)
+   - Solution-focused keywords (how do you help?)
+   - Audience-specific terms
+   - Industry terminology
+
+### Phase 3/8: Variations
+
+   For each seed keyword, generate variations:
+   
+   ```markdown
+   ## Keyword Expansion Patterns
+   
+   ### Modifiers
+   - Best [keyword]
+   - Top [keyword]
+   - [keyword] for [audience]
+   - [keyword] near me
+   - [keyword] [year]
+   - How to [keyword]
+   - What is [keyword]
+   - [keyword] vs [alternative]
+   - [keyword] examples
+   - [keyword] tools
+   
+   ### Long-tail Variations
+   - [keyword] for beginners
+   - [keyword] for small business
+   - Free [keyword]
+   - [keyword] software/tool/service
+   - [keyword] template
+   - [keyword] checklist
+   - [keyword] guide
+   ```
+
+### Phase 4/8: Classify
+
+   Categorize each keyword:
+
+   | Intent | Signals | Example | Content Type |
+   |--------|---------|---------|--------------|
+   | Informational | what, how, why, guide, learn | "what is SEO" | Blog posts, guides |
+   | Navigational | brand names, specific sites | "google analytics login" | Homepage, product pages |
+   | Commercial | best, review, vs, compare | "best SEO tools [current year]" | Comparison posts, reviews |
+   | Transactional | buy, price, discount, order | "buy SEO software" | Product pages, pricing |
+
+### Phase 5/8: Score
+
+   Score each keyword (1-100 scale):
+
+   ```markdown
+   ### Difficulty Factors
+   
+   **High Difficulty (70-100)**
+   - Major brands ranking
+   - High domain authority competitors
+   - Established content (1000+ backlinks)
+   - Paid ads dominating SERP
+   
+   **Medium Difficulty (40-69)**
+   - Mix of authority and niche sites
+   - Some opportunities for quality content
+   - Moderate backlink requirements
+   
+   **Low Difficulty (1-39)**
+   - Few authoritative competitors
+   - Thin or outdated content ranking
+   - Long-tail variations
+   - New or emerging topics
+   ```
+
+#### Opportunity Score
+
+   Formula: `Opportunity = (Volume × Intent Value) / Difficulty`
+
+   **Intent Value** assigns a numeric weight by search intent:
+   - Informational = 1
+   - Navigational = 1
+   - Commercial = 2
+   - Transactional = 3
+
+   ```markdown
+   ### Opportunity Matrix
+   
+   | Scenario | Volume | Difficulty | Intent | Priority |
+   |----------|--------|------------|--------|----------|
+   | Quick Win | Low-Med | Low | High | ⭐⭐⭐⭐⭐ |
+   | Growth | High | Medium | High | ⭐⭐⭐⭐ |
+   | Long-term | High | High | High | ⭐⭐⭐ |
+   | Research | Low | Low | Low | ⭐⭐ |
+   ```
+
+### Phase 6/8: GEO-Check — AI Answer Overlap
+
+   Keywords likely to trigger AI responses:
+   
+   ```markdown
+   ### GEO-Relevant Keywords
+   
+   **High GEO Potential**
+   - Question formats: "What is...", "How does...", "Why is..."
+   - Definition queries: "[term] meaning", "[term] definition"
+   - Comparison queries: "[A] vs [B]", "difference between..."
+   - List queries: "best [category]", "top [number] [items]"
+   - How-to queries: "how to [action]", "steps to [goal]"
+   
+   **AI Answer Indicators**
+   - Query is factual/definitional
+   - Answer can be summarized concisely
+   - Topic is well-documented online
+   - Low commercial intent
+   ```
+
+### Phase 7/8: Cluster
+
+   Group keywords into content clusters:
+
+   ```markdown
+   ## Topic Cluster: [Main Topic]
+   
+   **Pillar Content**: [Primary keyword]
+   - Search volume: [X]
+   - Difficulty: [X]
+   - Content type: Comprehensive guide
+   
+   **Cluster Content**:
+   
+   ### Sub-topic 1: [Secondary keyword]
+   - Volume: [X]
+   - Difficulty: [X]
+   - Links to: Pillar
+   - Content type: [Blog post/Tutorial/etc.]
+   
+   ### Sub-topic 2: [Secondary keyword]
+   - Volume: [X]
+   - Difficulty: [X]
+   - Links to: Pillar + Sub-topic 1
+   - Content type: [Blog post/Tutorial/etc.]
+   
+   [Continue for all cluster keywords...]
+   ```
+
+### Phase 8/8: Deliver
+
+   Produce a report containing: Executive Summary, Top Keyword Opportunities (Quick Wins, Growth, GEO), Topic Clusters, Content Calendar, and Next Steps.
+
+   **Quality bar** — every recommendation must include at least one specific number. If it reads like the left column, rewrite it before including.
+
+   | ❌ Generic (rewrite before including) | ✅ Actionable |
+   |---|---|
+   | "Target long-tail keywords for better results" | "Target 'project management for nonprofits' (vol: 320, KD: 22) — no DR>40 sites in top 10" |
+   | "This keyword has good potential" | "Opportunity 8.4: vol 4,800, KD 28, transactional intent — gap analysis shows no content updated since 2023 in top 5" |
+   | "Consider creating content around this topic" | "Write '[Tool A] vs [Tool B] for small teams' — 1,200/mo searches, current #1 is a 2022 article with 12 backlinks" |
+   | "Optimize your page for this keyword" | "Add primary keyword to H1 (currently missing), write a 40-word direct answer in paragraph 1, add 3 internal links from your /blog/ cluster" |
+
+   > **Reference**: See [references/example-report.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/research/keyword-research/references/example-report.md) for the full report template and example.
