React performance for lead-gen sites
Heavy client JavaScript is a silent tax on every HVAC emergency click and dental booking attempt.
Techniques we use in production
- Prefer server rendering for marketing pages
- Split admin-only code away from public routes
- Lazy-load below-the-fold carousels
- Avoid layout-thrashing animation libraries on landing pages
- Memoize only when profiling proves a need
- Optimize images before blaming React
- Keep third-party scripts out of the critical path
