User sentiment analysis

Users appreciate this WordPress plugin for its ability to significantly improve website speed and Google Page Speed scores, often in conjunction with other optimization plugins like Autoptimize. They find it easy to use, citing the wizard tool that simplifies the setup process, even for non-technical users. The support provided by the developer, Frank, is frequently praised for being prompt and helpful. However, some users experienced compatibility issues with plugins like WPForo, WP EasyCart, WooCommerce, and others, which sometimes disrupt website functionalities. Additionally, lack of advanced features in the free version, and occasional slowdowns during simulations are noted drawbacks. Despite these issues, the plugin is widely recommended.

I’ve been using this plugin for several months after it was suggested to me by a colleague. The setup was simple, but also gives advanced options that I needed, such as excluding certain scripts. I had an issue recently, and the developer provided fast and helpful support! I definitely recommend this plugin.

Exemplary support, and the plugin does exactly what it promises. This is unfortunately not a given in a time when many other plugins try to cover more and more tasks and end up in dangerous waters. Async JavaScript proves: Less is more.

This is the typical installation plugin you can’t miss in your project. Fulfill what you promise to do.

The plugin is easy to use. E.g with some videos on youtube. It improved our Google Page Speed significantly. And when I had a support question I got feedback within hours. Great Job. Keep up the good work
