About Page Optimize

This plugin can help improve the performance of your website by combining and optimizing CSS and JavaScript files. It also allows you to test these features on specific pages by appending query parameters to the URL.

Frequently asked questions

What does Page Optimize do?
Page Optimize is a WordPress plugin designed to improve page loading and rendering performance in the browser. It offers features like concatenating CSS and JavaScript, and managing the execution timing of non-critical scripts.
How can I test the plugin's features without affecting my live site?
You can test features by appending specific query parameters to a WordPress post or page URL. For example, to test JavaScript concatenation, you can add '?concat-js=1' to your URL.
What are the risks associated with changing script execution timing?
Changing script execution timing can be risky and may not work well for all websites. It's recommended to test this feature carefully.
Which query parameters are available for testing?
You can use 'concat-css' and 'concat-js' to control CSS and JavaScript concatenation, and 'load-mode-js' to manage how non-critical JavaScript loads. Values like 'defer' or 'async' can be used for 'load-mode-js'.
