Per the specification: > AMP HTML is a subset of HTML for authoring content pages such as news articles in a way that guarantees certain baseline performance characteristics. Source: https://www.ampproject.org/docs/reference/spec https://www.ampproject.org/docs/reference/spec Basically you have your website serve up your content within a subset of HTML so that your pages have to load faster. JavaScript is permitted but with limited functionality (again, the intent is your website loads quickly). Also, Google will host your webpage on their servers after crawling your website. When a user clicks on an AMP link from Google's search results, the content will be served up from Google's servers and thus the page will load much faster.
