Mobile commerce is growing rapidly as people increasingly rely on their mobile devices for product information and purchases. If businesses do not have a mobile website or mobile advertising, they are missing out on significant sales opportunities. Research shows that most shoppers now use mobile devices during shopping to look up prices, check inventory, and find deals. As smartphone usage increases, more consumers are making purchases directly from their phones. Mobile traffic now accounts for a large portion of online activity, so having a mobile strategy is essential for online retailers.
