Q9. One online shopping business found that 20% of shoppers quit during the checkout process without buying anything. A good next step would be:

  • Add a small pop-up window on the checkout page with the texts “We are sorry if you are having trouble when checking out. We will fix it later.”
  • When the reason that shoppers are dropping out of an online checkout is unknown, concluding that shoppers don’t understand the process well enough, are having second thoughts because prices are too high, or are simply irritated and need an apology, would be nothing more than a guess. A much better approach is to determine the real factors influencing dropout rates. This can be done through randomized experiments known as “A/B” Testing.
  • Shoppers are randomly assigned to one of two groups: a group using the current process, and a group where minor changes are made to the process which may improve customer retention. Changes that result in significant improvement are kept, and others discarded.
