+description: |
+  SEO reporting dashboard and executive report generation. Aggregates data from all SEO skills
+  into stakeholder-ready reports and interactive HTML dashboards.
+  Triggers: SEO report, SEO dashboard, executive summary, 보고서, 대시보드, performance report, 종합 보고서.
+---
+
+# SEO Reporting Dashboard
+
+## Purpose
+
+Aggregate outputs from all SEO skills (11-33) into stakeholder-ready executive reports with interactive HTML dashboards, trend analysis, and Korean-language summaries. This is the PRESENTATION LAYER that sits on top of skill 25 (KPI Framework) and all other skill outputs, providing a unified view of SEO performance across all audit dimensions.
+
+## Core Capabilities
+
+1. **Report Aggregation** - Collect and normalize outputs from all SEO skills (11-33) into a unified data structure with cross-skill health scoring and priority issue identification
+2. **Interactive Dashboard** - Generate self-contained HTML dashboards with Chart.js visualizations including health gauge, traffic trends, keyword distribution, issue breakdown, and competitor radar
+3. **Executive Reporting** - Korean-language executive summary generation with audience-specific detail levels (C-level, marketing team, technical team) and prioritized action items
+
+## MCP Tool Usage
+
+### Ahrefs for Fresh Data Pull
+```
+mcp__ahrefs__site-explorer-metrics: Pull current organic metrics snapshot for dashboard
+mcp__ahrefs__site-explorer-metrics-history: Pull historical metrics for trend visualization
+```
+
+### Notion for Reading Past Audits and Writing Reports
+```
+mcp__notion__*: Query SEO Audit Log database for past audit entries
+mcp__notion__*: Save dashboard reports and executive summaries to Notion
+```
+
+### Perplexity for Context
+```
+mcp__perplexity__*: Enrich reports with industry benchmarks and competitor context
+```
+
+## Workflow
+
+### Dashboard Generation
+1. Accept target domain and optional date range
+2. Query Notion SEO Audit Log for all past audit entries for the domain
+3. Optionally pull fresh metrics from Ahrefs (site-explorer-metrics, metrics-history)
+4. Normalize all skill outputs into unified format
+5. Compute cross-skill health score with weighted category dimensions
+6. Identify top issues (sorted by severity) and top wins across all audits
+7. Build audit history timeline
+8. Generate HTML dashboard with Chart.js charts:
+   - Health score gauge (doughnut)
+   - Category scores horizontal bar chart
+   - Health score timeline line chart
+   - Issue distribution pie chart
+   - Competitor radar chart (if competitor data available)
+9. Save HTML file and optionally push summary to Notion
+
+### Executive Reporting
+1. Load aggregated report data (from dashboard generation or JSON file)
+2. Select audience level: C-level, marketing, or technical
+3. Generate Korean-language narrative with:
+   - Health score overview and trend
+   - Category highlights (strengths and weaknesses)
+   - Skills coverage summary
+   - Audience-specific business impact analysis
+4. Format key wins and concerns with severity and category labels
+5. Generate prioritized action items ranked by impact
+6. Render as markdown document
+7. Optionally push to Notion SEO Audit Log
+
