- 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
- 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
- Minify CSS files

- Add missing image dimensions
- LazyLoad (defers images and videos until they’re visible on the screen)
- 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.
- Preloading (Allows you to define essential resources that should be loaded first)
- 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.
