+## Implementation Update (May 2026)
+
+The dashboard documentation has been verified against the active implementation, including:
+
+- Frontend route integration in `frontend/src/App.tsx` (`/seo`, `/seo-dashboard`)
+- Main dashboard orchestration in `frontend/src/components/SEODashboard/SEODashboard.tsx`
+- API coverage in `backend/api/seo_dashboard.py` for overview, analysis, integrations, competitive intelligence, and health diagnostics
+- Service orchestration via `backend/services/seo/dashboard_service.py`
+
+This keeps the existing detailed user documentation while ensuring endpoint and architecture references remain current.
+
+

+
+### Workflow enhancements connected to SEO
