With responsive design, all the same content will be displayed on every size screen, but the layout will be optimized for the size of the screen on the device. All the elements will automatically move around to fit.
Since the design of the page is actually optimized for the screen size, people don’t need to zoom in to get all of the important information. This is especially important since more people are making purchases and entering contests on phones than ever before. Approximately 43% of deals sales and 41% of contest entries come from mobile devices, and these numbers are only going to increase going forward. By the end of 2014, there are projected to be more mobile devices in the world than there are people!
Don’t underestimate the importance of responsive design as a way to maximize the success of your promotions.
