If you're in the United States reading this, I'm sure you're one of the 100 million people who own a smartphone. Smartphones have become as common as a pen in a pocket protector of some nerdy aeronautical or computer engineer in the 1980s. Maybe you're even reading these words on the device. But just because someone owns a smartphone doesn't mean they use it to conduct a search, make a purchase, download a white paper, or complete some other type of conversion. In fact, smartphone clicks convert at one-third the rate of desktops, whereas tablets convert at nearly the same rate as desktops, according to a recent white paper from BrightEdge.
