Autoptimize Plugin – install and configuration

Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default but can also inline critical CSS and defer the aggregated full CSS, moves and defers scripts to the footer and minifies HTML. This is a guide on how to install and configure the Autoptimize plugin.

2. Extra Auto-Optimizations

  • Google Fonts – Combine and link deferred in head (fonts load late, but are not render-blocking).

There are other options in the Extra section that can be useful in some situations, like Preconnect and Preload:

  • The preconnect directive allows the browser to setup early connections before an HTTP request is actually sent to the server.
  • Preload directives instruct your web browser to download an asset as soon as possible. This directive is useful for downloading assets that are needed very early in the page load process.

Note – This guide presents our case and for other situations it may not be optimal.
