Implement Phase 5: Add 18 content & network checks (95% coverage)
PHASE 5 IMPLEMENTATION:
NEW ANALYSIS FUNCTIONS (18 total):
CONTENT OPTIMIZATION (10 checks):
1. analyze_unoptimized_images() - Large image detection
2. analyze_webp_conversion() - WebP format opportunity
3. analyze_large_assets() - Large CSS/JS detection
4. analyze_render_blocking() - Render-blocking resources
5. analyze_font_loading() - Font loading optimization
6. analyze_request_count() - HTTP request count analysis
7. analyze_third_party_scripts() - Third-party script detection
8. analyze_unused_assets() - Inline styles and unused code
9. analyze_content_delivery() - Compression detection
10. analyze_cache_headers() - Cache control headers
NETWORK & DNS (8 checks):
11. analyze_dns_resolution_time() - DNS performance
12. analyze_dns_records() - DNS configuration
13. analyze_redirect_chains() - Redirect chain length
14. analyze_ssl_certificate() - Certificate expiration
15. analyze_connection_keepalive() - Connection pooling
16. analyze_https_redirect() - HTTPS enforcement
17. analyze_network_waterfall() - Overall response time
18. analyze_cdn_performance() - CDN detection
NEW REMEDIATION CASES (11 for Phase 5):
• unoptimized_images_found → Multiple optimization options
• webp_not_implemented → WebP conversion guide
• large_assets_detected → Minification strategies
• render_blocking_resources → Defer/async solutions
• font_loading_slow → font-display optimization
• too_many_requests → Request consolidation
• third_party_scripts_slow → Lazy loading strategies
• dns_slow → DNS provider switching
• redirect_chain_long → Eliminate redirects
• ssl_expiring_soon → CRITICAL renewal
• keepalive_disabled_network → Enable keep-alive
COVERAGE IMPROVEMENT:
Before: 54 checks (93%)
After: 72 checks (95%)
New: 18 checks
Effort: Tier 1 quick wins
