The AMP Project is an open-source initiative aiming to make the web better for all. AMP enables web experiences that are consistently fast, beautiful and high-performing across distribution platforms. AMP formerly stood for “Accelerated Mobile Pages”, but now works completely across desktop and mobile. The official AMP plugin for WordPress supports fully integrated AMP publishing for WordPress sites, with robust capabilities and granular publisher controls.
Features and capabilities provided by the plugin include:
- AMP-first Experiences: enabling full-site AMP experiences without sacrificing the flexibility of the platform or the fidelity of content.
- Core Theme Support: enabling AMP compatibility for all core themes, from Twenty Ten all the way through Twenty Twenty.
- Compatibility Tool: when automatic conversion of markup to AMP is not possible, debug AMP validation errors with detailed information including the invalid markup and the specific components responsible on site (e.g theme, plugin, embed); validation errors are shown contextually with their respective blocks in the editor.
- CSS Tree Shaking: automatically remove the majority of unused CSS to bring the total under AMP’s 75KB limit; when the total after tree shaking is still over this limit, prioritization is used so that the all-important theme stylesheet important is retained, leaving less important ones to be excluded (e.g. print styles).
- Server-side Rendering: integrated PHP-port of the AMP Optimizer providing automated server-side rendering of AMP pages, drastically improving the Last Contentful Paint (LCP) metric.
Please note that the Stories experience has been removed from the AMP plugin in favor of the feature being released as a standalone plugin. It will be available soon!
The plugin can be configured to follow one of three different template modes: Standard, Transitional, and Reader. In Standard mode you use AMP as the framework for your site, and there need not be any separate AMP and non-AMP versions. When configured to operate in Reader and Transitional modes, a given page will have a canonical URL as well as a corresponding (paired) AMP URL. The AMP plugin is not serving as a mobile theme; it does not redirect mobile devices to the AMP version. Instead, the AMP version is served to mobile visitors when they find the content on platforms such as Twitter, Pinterest, Google Search, and others. Reader mode only supports serving AMP for singular posts, pages, and other post types, whereas Standard and Transitional mode support serving the entire site as AMP.
With the official AMP plugin for WordPress, the WordPress ecosystem is provided with the capabilities and tools it needs to build world-class AMP experiences without deviating from its standard, flexible, and well-known content creation workflow.
