Today, having a mobile-friendly site isn’t just a suggestion; it’s a necessity. Research shows that 91% of all smartphone users have their device within arm’s reach, 24 hours a day, 7 days a week. And by 2021, it’s estimated that nearly 54% of e-commerce will be conducted via mobile device . Even when consumers make their purchases offline, much of their preliminary research is conducted via their phone screen. But have you ever tried to access a website that wasn’t smartphone-friendly? It’s nearly impossible: pinching and zooming to get your finger in just the right spot to click the link you need, or scrolling from side to side just to be able to see or read all the content on the page. It’s no fun.
