Articles that are displayed on AMP-ready sites are going to receive a boost in Google News searches. AMP has existed since 2015 and it is already used by many sites to reduce load times and gain a special status in Google searches. The change to Google News affects mobile searches. Pages that use AMP will have a circular plus icon and the AMP name near them.
While other factors are still important for ranking, a site's use of AMP will give it an edge in Google News, potentially resulting in more views. This improves the user experience since AMP pages load in under a second and can use far less data.
Among the sites currently using AMP are Vox Media, CBS, BuzzFeed, and The New York Times. In total, there are 600 million pages that meet the AMP specification.
