A mobile friendly website is essentially when your regular website shrinks down to be small enough to display on a mobile device. It looks like a tiny version of your website. There’s a lot of zooming, pinching and scrolling going on, but the site displays and functions.
Now, if Google thinks your website isn’t “mobile friendly” it’s not going to show up in searches done on mobile devices. This should NOT affect how your site performs on desktop/laptop searches.
