 ## [Unreleased]
 
+### Fixed
+- **SEO audit fixes** — sitemap: replaced `/market-score` with `/padelnomics-score`, added `/opportunity-map`, removed `/billing/pricing` (blocked by robots.txt), deduplicated articles query (was producing 4 entries per article instead of 2). Fixed `/market-score` redirect chain (1 hop instead of 2). Moved default OG tags inside `{% block head %}` so child templates replace rather than duplicate them. Added JSON-LD WebPage + BreadcrumbList schema to features, planner, and directory pages. Added meta descriptions to export pages.
+
 ### Changed
 - **Opportunity Score v7 → v8** — better spread and discrimination across the full 0-100 range. Addressable market weight reduced (20→15 pts) with steeper sqrt curve (ceiling 1M, was LN/500K). Economic power reduced (15→10 pts). Supply deficit increased (40→50 pts) with market existence dampener: countries with zero padel venues get max 5 pts supply deficit (factor 0.1), scaling linearly to full credit at 50+ venues. NULL nearest-court distance now treated as 0 (assume nearby) instead of 0.5. Added `country_percentile` output column (PERCENT_RANK within country). Target: P5-P95 spread ≥40 pts (was 22), zero-venue countries avg <30.
 - **Opportunity Score v6 → v7 (calibration fix)** — two fixes for inflated scores in saturated markets. (1) `dim_locations` now sources venue coordinates from `dim_venues` (deduplicated OSM + Playtomic) instead of `stg_padel_courts` (OSM only), making Playtomic-only venues visible to spatial lookups. (2) Country-level supply saturation dampener on the 40-pt supply deficit component: saturated countries (Spain ~4.5/100k) get dampened supply deficit (×0.55 → 22 pts max), emerging markets (Germany ~0.7/100k) are nearly unaffected (×0.93 → ~37 pts).
