Retailers are losing $18 billion annually due to shopping cart abandonment. Research shows over two out of three users who add items to their online shopping cart leave without making a purchase. The numbers are even worse on mobile, where conversion rates are 70 percent lower than desktop. So why are consumers leaving right at the point of sale and what can companies do about it?

Even multi-million and multi-billion-dollar companies are failing to implement some of the critical best practices for checkout. In this slideshow, Moovweb has incorporated the findings of leading research center on e-commerce usability Baymard Institute to categorize six types of best practices that you can apply to your mobile checkout and increase conversions up to 25 percent.
