Capturing an adult’s attention is hard enough — the average attention span of an adult is just eight seconds, according to the U.S. National Library Association. That attention span shrinks to just four seconds when shopping online, and during the holidays there is more information than normal clamoring for attention.

To reduce shopping cart abandonment, retailers are streamlining their mobile checkout process by reducing the number of clicks require to complete a purchase. Adding simple technology, such as @Pay Buttons, to their emails is one way to capture revenue in just a few seconds — as little at two clicks. During the holidays, the number of emails being read on smartphones and tablets will increase and by the end of November 2014, it is predicted that mobile will account for more than 20% of site sales!
