Smartphones and tablets are driving an increasing amount of traffic, and the numbers are only going to grow as mobile devices become cheaper and more mainstream. Andy Chu, director of Bing for Mobile, says 70% of task completion happens within one hour on mobile sites, meaning that people are often browsing on the web with intent — they're looking to do something, buy something or go somewhere. If someone searches for a restaurant on his smartphone, he's likely to eat at that restaurant within the hour, says Chu. So your website better be readable on handheld devices.
"Until two years ago, designing for the web meant designing for a computer, now it means designing for anything with an internet connection," says Frankel, referring to laptops, tablets and smartphones, all of which have different screen sizes. So, how can you do it? Responsive design.
Responsive website design enables you to use fluid widths, so that your website layout will adapt to the screen on which it's being browsed. Layouts are adjustable and images are scalable to make for a better web experience on myriad devices.
