Nowadays, most website visits come from mobile users—over 60% of internet traffic is on phones. But there’s a big difference between a website that’s available on mobile, and one designed for it.    Websites that are optimized for mobile use should load super-fast, not have intrusive elements like pop-ups, be easy to read, and have an easy-to-navigate design. If your website isn’t well optimized for mobile, users could leave quickly, which signals to Google that your website’s not worth checking out. Worst of all, it could end up losing you customers.
