HEY EXPERTS, My website page speed is not increasing. I used the wp rocket plugin but still, I am facing errors of Reduce unused CSS, Properly size images, and Avoid serving legacy JavaScript to modern browsers. you can see in the image Screenshot (7).png I used many plugins for speed optimization but still facing errors. I optimized the images manually by using photoshop but still, I am facing the issue of images size. After Google Core Web Vital Update my website keyword position is down due to slow speed. Please guide me on how I increase the page speed of my website https://karmanwalayfabrics.pk Thanks
