 ## [Unreleased]
 
+### Added
+- **SEO/GEO admin hub** — syncs search performance data from Google Search Console (service
+  account auth), Bing Webmaster Tools (API key), and Umami (bearer token) into 3 new SQLite
+  tables (`seo_search_metrics`, `seo_analytics_metrics`, `seo_sync_log`); daily background
+  sync via worker scheduler at 6am UTC; admin dashboard at `/admin/seo` with three HTMX tab
+  views: search performance (top queries, top pages, country/device breakdown), full funnel
+  (impressions → clicks → pageviews → visitors → planner users → leads), and per-article
+  scorecard with attention flags (low CTR, no clicks); manual "Sync Now" button; 12-month
+  data retention with automatic cleanup; all data sources optional (skip silently if not
+  configured)
+
 ### Changed
 - **pSEO CMS: SSG architecture** — templates now live in git as `.md.jinja` files with YAML
   frontmatter (slug, data_table, url_pattern, etc.) instead of SQLite `article_templates` table;
