Here is the harsh reality of e-commerce websites: according to recent e-commerce studies, at least 59.8% of potential customers abandon their shopping cart (MarketingSherpa puts it at 59.8%, SeeWhy at 83% and MarketLive at 62.14%). The main question is why do customers abandon their shopping cart so often? Is there some fundamental mistake that designers of e-commerce websites do very often? Are there any common guidelines or rules of thumbs that make it more difficult for our users to purchase products? And is there some meaningful way to improve the conversion rates for our products?
Well, that's exactly what we wanted to find out. In 2010, we recruited a batch of Web users and conducted a usability study, focusing only on the checkout user experience, from “Cart” to “Completed order.” The study was conducted using the “think aloud” protocol and was documented by recording everything that happened on the computer screen. The behavior of the test subjects was then analyzed by scrutinizing these recordings at a later date.
