We’ve been optimizing web on mobile for over a decade now (you might know one of our popular projects, Lazy Load XT on Github). PageSpeed Ninja for WordPress is the result of 10+ years of experience in optimizing the performance over 200 000 websites on mobile. We believe you won’t find a similar, easy to use, all-in-one package of performance boosting features anywhere else. We’ve built heaps of unique features to make sure your site loads super fast, like the above-the-fold critical CSS generation method, not seen in any other plugins. We’d love your feedback – always feel free to send us your questions, thoughts and suggestions. Before you install According to our stats, our plugin improves speed of 4 out of 5 sites. However in some cases, certain theme and plugin combinations (particularly related to caching and optimization) cause incompatibility issues. Therefore our plugin might not be suitable for everyone. In order for you to see how PageSpeed Ninja could work on your site, we created a simple tool where you can test your site before installation. We highly recommend you visit PageSpeed.Ninja and test your site beforehand. Uninstallation When the plugin is deleted, it will automatically revert all settings on your site back to way they were before installing this plugin. It restores all optimized images and removes /s directory with optimized JS and CSS files. Also all changes in .htaccess files are reverted back. Please note that this restoration may not work reliably if in the meanwhile there have been any conflicts with other plugins, e.g. if the other plugins dynamically create/edit/remove files (including the files backed up by this plugin). Feedback, Bug reports, Logging possible issues We welcome all questions, comments, suggestions, issue reports. Contact us to be added to our private tester Facebook group. PageSpeed Ninja logs all php errors in wp-content/plugins/pagespeedninja/includes/error_log.php file (see Troubleshooting section in Advanced tab of the PageSpeed Ninja settings page) If you find a problem, would be great if you can also send that file along.
