WP Rocket is my go-to premium plugin for WordPress speed and caching.
I have it installed on three websites right now, and it has helped my speed rise in tests on GT Metrix, Pingdom, and Google’s PageSpeed Insight.
WP Rocket is loaded with features, with some of them giving users the ability to remove other plugins they may have installed – for instance, users can set up automated database and post revision cleaning, lazy loading for images and videos, and WordPress heartbeat control
It also integrates with CDN services like CloudFlare, and syncs with Sucuri via API, among other features.
If you’re looking for a step up from a freemium plugin and want to get your speed higher… blast off with WP Rocket!
