What caching-strategies help reduce lcp and fid delays?
Asked on Sep 14, 2025
Answer
Effective caching strategies can significantly reduce LCP (Largest Contentful Paint) and FID (First Input Delay) by minimizing server response times and reducing the need for repeated resource downloads. Implementing browser caching and server-side caching are key techniques.

- Use "Cache-Control" headers to specify how long browsers should cache resources.
- Implement server-side caching (e.g., Varnish, Redis) to store and quickly serve dynamic content.
- Consider using a Content Delivery Network (CDN) to cache and deliver static assets closer to users.
- Ensure cache busting strategies are in place to handle updates without stale content.
