AMP is an open source technology by Google. It provides the users with a faster-loading mobile website experience.
AMP pages are identified with a lightning bolt symbol on the top right corner of the featured articles.
AMP is specially designed for consumption of content through “reading” and does not have any interactive components.
The average page-loading time of an AMP is less than one second (link is external). This is why AMP has been widely adopted; more than 900,000 domains have published more than 2 billion AMP pages (link is external).
