BLOG FILTER



When the defer attribute is present in the script tag, it specifies that the script is executed when the page has finished parsing. A requirement that is enforced by Google for example (Page-Speed ranking).

Currently the WordPress wp_enqueue_script provides no easy way to add new attributes, but there is a way around that :)
The below hack / filter needs to be added to your theme function.php. The filter should be your preferred solution, as the clean_url filter has been deprecated.

Make sure that your website / theme is still loading after adding these changes. If needed you can add more exceptions, as I did for jQuery.

Compressing your content saves bandwidth and improves render time, particular on devices with slow internet connections. Compression allows your web server to provide smaller file sizes that load faster for your visitors. Compression of your HTML and CSS files with gzip typically saves around 50 to 70 % of the file size.

Check if GZIP Compression is active on your website

  1. HTTP Compression test
  2. Check GZIP Compression

Adding GZIP Compression via your htaccess (Apache)

Adding GZIP Compression on NGINX

Adding GZIP Compression via a WordPress Plugin

A good candidate is the WP Far Future Expiration Plugin ,which not only activates GZIP compression but adds file expiration for various static file types.

IN A PERFECT WORLD

In a perfect world all current browsers would allow the usage of WebRTC natively, but that is as always not the case ;)
