WPO Tweaks & Performance Optimizations

WPO Tweaks is the most complete performance optimization plugin for WordPress. It combines the best WPO (Web Performance Optimization) practices in a single easy-to-use tool. No configuration needed: activate and enjoy a faster WordPress.

By default, WordPress loads several functions, services and scripts that are not mandatory and usually slow down your installation and consume hosting resources. For years I have been testing tweaks to save hosting resources and improve WordPress performance and loading times. After thousands of tests, this plugin includes my best speed and performance optimizations with a single click.

With this plugin you can safely disable those annoying services, unnecessary codes and scripts to save resources and hosting costs, and speed up WordPress to get better results in tools like Google PageSpeed, Pingdom Tools, GTMetrix, WebPageTest and others.

HOW TO VERIFY OPTIMIZATIONS ARE WORKING

You can check each optimization individually to ensure WPO Tweaks is working correctly:

Missing Image Dimensions: Inspect images in your browser (F12 > Elements). Images should have width="X" and height="Y" attributes even if they weren’t originally coded with dimensions.

Critical CSS: View page source (Ctrl+U) and look for
