Using AMP plugins with WP Rocket

AMP (Accelerated Mobile Pages) is Google's open-source project built to speed up websites’ loading time. Initially, it was aimed for mobile but now it has been extended to all kind of devices.

Compatible plugins

WP Rocket has built-in, automatic compatibility with:

However, WP Rocket will deactivate these incompatible features: Minification, DNS Prefetch, LazyLoad, Optimize CSS delivery (Load CSS Asynchronously and Remove Unused CSS), Load JavaScript deferred, Delay JavaScript Execution, Google Fonts Optimization, and the CDN rewrites will work for the images only.
