Testing your website speed is one of the best ways to see how much the plugin is really helping. Before activating the plugin, you should take a screenshot of your current scores so you can compare them later. The easiest and most reliable tool is Google PageSpeed Insights. Simply go to the website, enter your URL, and run the test for both mobile and desktop. This will give you clear numbers about your loading time, Core Web Vitals, and overall performance score. After activating the plugin, run the test again after a few minutes. You will most likely see a big improvement in your scores, especially in Largest Contentful Paint and Cumulative Layout Shift.

Once you get used to checking your speed regularly, it becomes very easy to track your progress over time. Many users like to test their site every week to make sure everything is working well. Remember that real user experience is what matters most — so also try opening your site in a normal browser and see how fast it feels. The combination of good PageSpeed scores and a smooth real experience is the best sign that the plugin is doing its job properly.
