With the continuous growth of mobile traffic, many developers began designing websites using a mobile-first approach. That is, rather than designing the website for a computer and then making the website responsive to the mobile phone, they now design the website for the mobile first and then computer. This approach and ongoing growth of mobile traffic has led to the creation of AMP—Accelerated Mobile Pages.
As the name suggest, AMP allows web developers and web designers to create faster-loading websites. They provide instantaneous access to all the information in the page, and according to statistics, lead to a 20% increase in website traffic.
