Take note that Microsoft had previously implemented AMP into some of its apps, including the Bing app. However in this particular instance, what Microsoft has done is added AMP support to Bing on the web, meaning that if you are using Bing in your mobile browser, you should still be able to access websites that use Google’s AMP feature.
According to Microsoft’s announcement on the Bing blog, “Today, we are pleased to announce the release of Bing AMP viewer and Bing AMP Cache enabling AMP-enabled web pages to work directly from Bing’s mobile search results allowing Bing to provide faster mobile experiences to Bing users.”
“On Monday, the 17th we started the first phase of the global roll out of this AMP viewer and AMP carrousel in the United States for the news carrousel. We will continue the phased roll out to more web sites, more countries and regions and other links in the search results pages.” So if you are more of a Bing user, these are the changes and improvements that you can look forward to.
