Accelerated Mobile Pages (AMP) is an open-source framework created by Google, Twitter, and others to make mobile webpages load faster. AMP pages use lightweight HTML, JavaScript, and CSS to reduce loading times. They are cached on Google's servers to load quickly. AMP pages have benefits like increased speed, improved visibility in Google search results through AMP symbols, potential for better search rankings due to speed improvements, and easier user tracking and analytics. AMP helps increase mobile site speed and will likely dominate mobile interactions on social media in the future.
