The majority of web traffic today comes from mobile devices. There’s nothing more frustrating than visiting a site on your phone only to discover it wasn’t designed to work on mobile. Misplaced images, broken menus, disappearing text — these are enough drive your visitors straight into the arms of your competition. Responsive website design adapts the page’s layout to the user’s viewing environment through the use of fluid, proportional grids and flexible imagery. In short, it responds to the visitor’s device to serve up the best individual experience for that user. This isn’t just about keeping your users happy. Responsive web design is a significant factor in search ranking. If Google crawls your site and learns that it isn’t mobile-ready, you can expect to take a severe plunge in their rankings.
