Process

WP Rocket

1. Install WP Rocket Plugin
   • Dashboard – Plugins – Add New – Upload Plugin (Drag wp-rocket_version#.zip file or Choose File) – Click Install Now
2. Activate WP-Rocket
3. Settings
   1. Caching
      • A way to temporarily store copies of files, so it can be delivered to visitors in a more efficient way.
      • Enable caching for mobile devices
   2. File Optimization  ⚠️ If you choose to minify, combine, and defer your JS – things may break on your site. It’s important to test your site’s functions before permanently leaving it on.
      • Minify CSS files
        • Minify CSS removes whitespace and comments to reduce the file size.
      • Combine CSS files
        • wordpress site often includes many css files. Some for themes and some for plugin
        • files are loaded either using HTTP1 or HTTP2
        • HTTP 1.1 files are loaded consecutively – combining css will help loading the files
        • HTTP 2 files are loaded concurrently
        • Check if your site provides HTTP1 or HTTP2: https://tools.keycdn.com/http2-test
      • Optimize CSS delivery
        • generate css needed for content above the fold and asynchronously load other css files so they don’t block the rendering process.
      • Minify JavaScript files
        • Minify JavaScirpt removes whitespace and comments to reduce the file size
      • Combine JavaScript files (Enable Minify JavaScript files to select)
        • not recommended if your website uses http2
      • Load JavaScript deferred
        • delay the loading of js files so the most important content like html and css can be deliverd first (most cases fixes eliminate render-blocking resources)
      • Delay JavaScript execution
        • Do not select – conflict with Google Re-captcha
   3. Media
      • LazyLoad (defers images and videos until they’re visible on the screen)
        • Enable for images
        • Enable for iframes and videos
        • Replace YouTube iframe with preview image
      • Image Dimensions (Add missing width and height attributes to images. Helps prevent layout shifts and improve the reading experience for your visitors)
        • Add missing image dimensions
   4. Preload
      • Preloading (Allows you to define essential resources that should be loaded first)
        • if you look in html file, JS loads first simply because of hierarchy.
        • but if we add another link tag to preload the stylesheet, and this would tell browsers, load css file in higher priority than javascript file.
   5. CDN
      • Using CDN – Content Delivery Network
        • caching files on multiple servers globally, then when a visitor tries to access your site, it’ll connect them to the one that’s closest, creating faster connection between user and content.
