The acronym AMP stands for Accelerated Mobile Pages. The AMP project was built thanks to a collaboration between thousands of programmers, publishers and sites, distribution platforms and technology companies.

The project allows faster and faster site creation, loaded almost instantaneously on mobile devices, going from the usual and seconds that as mobile pages are time consuming and are loaded for only two seconds.

AMP pages not only are very useful for faster browsing but also spend less mobile data, which is great for internet users. According to Google, pages that use AMP use 10 times less data in searches than equivalent pages without this technology. Google has been gradually integrating AMP into search results, starting in August 2016 to show AMP sites in search results on mobile devices. Currently, when you're using a smartphone or tablet, you'll see a symbol that indicates that a certain page uses AMP.

But how does it work? AMP pages are built with three main components.

• HTML AMP: AMP HTML is basically HTML with some restrictions for reliable performance with custom properties. These custom elements make common standards more efficient.

• AMP JS: An AMP JS library ensures fast rendering of AMP HTML pages. One of the biggest optimizations is the fact that everything that comes from external resources is asynchronous, so no element on the page blocks rendering

• AMP Cache: Google AMP Cache can be used to display cached HTML AMP pages. The cache also comes with a built-in validation system that confirms that a page is up and running and does not depend on external resources.

Some examples of sites with good use of AMP are The New York Times, The Washington Post, El País, or in Portugal, the sports newspaper Record, and video website Vídeos- rir.
