CoffeeCup Website Insight Case Study: Turning Visitors into Customers

7 Quick Wins from CoffeeCup Website Insight for Faster Page Loads

1. Enable gzip/ Brotli compression
   Use CoffeeCup’s resource reports to find large text assets (HTML, CSS, JS) and enable gzip or Brotli compression on your server — reduces transfer size significantly.

2. Minify CSS and JavaScript
   Identify unminified files in the audit and minify them (remove whitespace/comments). CoffeeCup highlights heavy scripts and styles so you can target the biggest wins first.

3. Defer or async noncritical JavaScript
   CoffeeCup flags render-blocking scripts. Add defer or async attributes to nonessential JS to prevent blocking initial rendering and speed First Contentful Paint.

4. Optimize and lazy-load images
   Use the image-size and load-time data to convert oversized images to modern formats (WebP/AVIF) and implement lazy-loading for below-the-fold images to cut initial payload.

5. Leverage browser caching / set proper cache headers
   CoffeeCup shows cache status for assets. Add long-lived cache headers (Cache-Control, ETag) for static resources and shorter or validation-based caching for frequently changing files.

6. Remove unused CSS and JS
   The tool highlights unused code. Eliminate or split out rarely used styles/scripts so initial pages only download what’s necessary, improving load and parse times.

7. Prioritize critical CSS and reduce render-blocking resources
   Extract and inline critical-path CSS for above-the-fold content (CoffeeCup shows which styles affect initial render) and defer the rest to reduce time to first meaningful paint.

If you want, I can convert these into a short checklist with specific commands/snippets for common servers (Apache, Nginx) and build tools (Webpack, Vite).
