I made some changes in preferences, and added a few plugins to make my site load faster. It helped with a desktop version – from 51 to 73 in PageSpeed Insights.
But mobile mode load time is still very low and hasn’t changed at all. What can I do to make it load faster?
Try to reduce the number of plugins and sizes of images you use. So we suggest you remove unnecessary plugins, install some kind of JS & CSS optimizing plugins like Better WordPress Minify and a caching plugin like WP Super Cache. Also, you can use GTmetrix tool to see what makes your website slow and optimize these parts of your website.
