Global tablet traffic now exceeds smartphone traffic, with the UK leading this trend. Tablet traffic grew 100% last year and is expected to continue rising in 2013. Tablets are preferred for retail and ecommerce activities because their large screens make for comfortable online shopping. Marketers should optimize their websites for both smartphones and tablets separately, as consumers use different devices for distinct purposes and have varying expectations from each. An unsatisfying experience on one could cause them to go elsewhere.
