Back in late 2014, Google said it was experimenting with giving sites that have earned its new mobile-friendly label some type of special treatment within its ranking algorithm.
Since Google already penalizes sites that provide a bad experience to mobile searchers this was a natural next step since Google is big on rewarding sites providing a great customer experience.
