If your website isn’t mobile-friendly, then it won’t show up in search engine results. What does mobile-friendly mean? A mobile-friendly website is one that shrinks down to accommodate the various mobile devices on the market. It’s like a mini version of your website. Having a non-responsive website can lead to poor user experience. That means your users will end up pinching, scrolling, and zooming. With a mobile-friendly website, your site is viewable across all devices.
