site mobile friendliness is now considered as a google search engine signal.

today I logged into my adsense and this was the msg it said, "site mobile friendliness is now considered as a google search engine signal". I just want to know if it will bring me more ppl from the search engine or if it's just like a badge of honor and nothing more. please and thank you.

Non-mobile friendly sites will rank lower, but page authority will still win the day most likely.

thank you very much for the incite
