Async JavaScript vs Simple Lazy Load Videos

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 plugin reduces page load time and increases your Google PageSpeed score. It replaces the embedded YouTube and Vimeo videos with a video preview image, third-party CSS & JS are downloaded only after a click.
