Database Schema: - Added meta_description TEXT field to pages table - Added index on status_code for faster broken link queries Backend Changes: - Crawler now extracts meta descriptions from pages - New API endpoint: broken-links (finds 404s and server errors) - New API endpoint: seo-analysis (analyzes titles and meta descriptions) SEO Analysis Features: - Title length validation (optimal: 30-60 chars) - Meta description length validation (optimal: 70-160 chars) - Detection of missing titles/descriptions - Duplicate content detection (titles and meta descriptions) Frontend Changes: - Added "Broken Links" tab showing pages with errors - Added "SEO Analysis" tab with: * Statistics overview * Pages with SEO issues * Duplicate content report All quality checks pass: - PHPStan Level 8: 0 errors - PHPCS PSR-12: 0 warnings 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
