✅ Speed Optimization Checklist

🖼️ Images

Compress images (TinyPNG, ShortPixel, Squoosh)

Use modern formats (WebP, AVIF) with fallbacks

Implement lazy loading for below-the-fold images

Serve responsive images with srcset

Use a CDN for image delivery (Cloudflare, BunnyCDN, imgix)

📦 Code & Assets

Minify CSS files

Minify JavaScript files

Remove unused CSS (PurgeCSS)

Defer non-critical JavaScript (defer/async attributes)

Inline critical CSS for above-the-fold content

Reduce third-party scripts (analytics, chat widgets, ads)

🌐 Server & Network

Enable GZIP or Brotli compression

Use a CDN (Cloudflare, Fastly, CloudFront)

Enable HTTP/2 or HTTP/3

Set proper cache headers (Cache-Control, ETag)

Use DNS prefetch / preconnect for external resources

Choose a server location close to your audience

💾 Caching

Enable browser caching for static assets

Use server-side caching (OPcache, Varnish, Redis)

Implement page caching (WP Super Cache, W3 Total Cache)

Cache database queries where possible

📐 Core Web Vitals

LCP (Largest Contentful Paint) under 2.5s — optimize hero images/fonts

INP (Interaction to Next Paint) under 200ms — minimize JS blocking

CLS (Cumulative Layout Shift) under 0.1 — set image dimensions, avoid late-loading ads

🗄️ Database

Optimize database tables (remove post revisions, spam comments)

Add proper database indexes

Use object caching (Redis/Memcached) for database results
