How does AMP work?
AMP versions of your website’s pages are created in the background, pushed to Google and stored in Google’s cache which further reduces load time. When a mobile user initiates a search and an AMP version of your website is available, the AMP version will be presented to the user. AMP pages are identified in the search results by the lightning bold icon as shown in the example below. More details on the technical aspects of AMP can be found here. https://amp.dev/
