Accelerated Mobile Pages ( AMP ) for WordPress
AMP allows content publishers to streamline content templates with an open-source framework named AMP HTML.
Websites that opt into this framework benefit from speed improvements since the content templates share common elements and components, leading to a 15 to 85% performance improvement, according to Google.
From the search engine results page, users can click through to a list of AMP-compliant partner sites. Doing so will load that content almost instantaneously, as Google will also pre-render content above the fold for AMP listings.
Once a user clicks through, there is a persistent blue bar at the top with a call to action to return to the Google SERP.
