What is AMP (Accelerated Mobile Pages)?
Accelerated Mobile Pages (AMP) は、サイト所有者がサイトのモバイル対応バージョンを作成できるようにするオープンソース HTML フレームワークです。
Google spearheaded the AMP project and was popular back when most sites were not mobile-friendly. Instead of developing a mobile version of their site separately, a site owner could create an AMP version of their website for mobile devices.
AMP started appearing in Google results in February 2016. Google hosted the cached AMP version of a website on its own servers. They were easier to navigate, loaded faster, and used less data than regular web pages.
But Google dropped preferential treatment for AMP sites with the June 16 – September 2, 2021 ページエクスペリエンスの更新. Several other sites have also ended support or preferential treatment for AMP sites.
ノート： While AMP originally stood for Accelerated Mobile Pages, in 2019, グーグル revealed that AMP is a standalone word and no longer an acronym for Accelerated Mobile Pages.
