About this plugin

Eliminate Render-blocking Javascript in above-the-fold content with Async Javascript.

Render-blocking Javascript prevents above-the-fold content on your page from being rendered until the javascript has finished loading. This can impact on your page speed and ultimately your ranking within search engines. It can also impact your user’s experience.

Async JavaScript gives you full control of which scripts to add an ‘async’ or ‘defer’ attribute to or to exclude to help increase the performance of your WordPress website.

The ‘async’ attribute is new in HTML5. It is supported by the following browsers:

  • Chrome
  • IE 10 and higher
  • Firefox 3.6 and higher
  • Safari
  • Opera

Where can I get help?

Async JavaScript is supported via the wordpress.org support forum.

Do you offer professional support/ configuration services?

What about CSS?

As the name implies, Async JavaScript is built to enhance JavaScript loading only. Async JavaScript does not have any impact on CSS.

We recommend using the awesome Autoptimize plugin alongside Async JavaScript for CSS optimization.
