+## 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 + ~~analytics + ~~AI monitor connected:**
+Automatically pull ranking positions from ~~SEO tool, search impressions/clicks from ~~search console, traffic data from ~~analytics, and AI Overview citation tracking from ~~AI monitor. Daily automated rank checks with historical trend data.
+
+**With manual data only:**
+Ask the user to provide:
+1. Keyword ranking positions (current and historical if available)
+2. Target keyword list with search volumes
+3. Competitor domains and their ranking positions for key terms
+4. SERP feature status (featured snippets, PAA appearances)
+5. AI Overview citation data (if tracking GEO metrics)
+
+Proceed with the full analysis using provided data. Note in the output which metrics are from automated collection vs. user-provided data.
+
+## Instructions

+
+3. **Analyze Ranking Changes** -- Overall movement metrics, biggest improvements and declines with hypothesized causes, recommended recovery actions, stable keywords, new rankings, lost rankings.
+
+4. **Track SERP Features** -- Feature ownership comparison vs competitors (snippets, PAA, image/video pack, local pack), featured snippet status, PAA appearances.
+
+5. **Track GEO/AI Visibility** -- AI Overview presence per keyword, citation rate and position, GEO performance trend over time, improvement opportunities.
+
+6. **Compare Against Competitors** -- Share of voice table, head-to-head comparison per keyword, competitor movement alerts with threat level.
+
+7. **Generate Ranking Report** -- Executive summary with overall trend, position distribution, key highlights (wins/concerns/opportunities), detailed analysis, SERP feature report, GEO visibility, competitive position, recommendations.
