Here’s a brief overview of 10 ways to reduce mobile cart abandonment and help increase conversions.

The cost of losing customers at checkout is a lot higher than you might think. Baymard reports that ecommerce sites can increase their conversion rate by 35% solely through a better checkout design. This increase in conversion rate translates to $260 billion in lost orders. Have you considered how many orders you are losing to standard design checkout flaws?

Amazon Pay recently commissioned a new mobile research study from the Baymard Institute examining the ways customers interact with a mobile checkout experience. To help you create the best experience for your customers, this 10in20 webinar is focused on simple solutions you can start acting on today to optimize your mobile checkout.

What is 10in20?

It’s a monthly series where we cover one topic in 10 questions, points, or ideas, and we do it in 20-minutes or less. Why so short? We recognize your time is precious; we have condensed our thought leadership webinar series from the typical hour into 20 minutes.

10 ways to reduce mobile cart abandonment and increase conversion

As you look for ways to create convenient shopping experiences on behalf of your customers, we’ve developed a short list of 10 ways to retain mobile shoppers during the checkout process. Here’s a recap of the main points from our webinar:

  1. Make ‘Guest Checkout’ the most prominent option at account selection, and hide username and password fields until the user selects the ‘Sign In’ or ‘Create Account’ option.
  2. Provide appropriate touch keyboard layouts for select fields — such as the email, credit card, and zip/postal code fields — to help users quickly and easily type their information.
  3. Facilitate easy typing and verification of the credit card number by auto-formatting the card number with spaces that match how the number is printed on the user’s physical card.
  4. Format the credit card expiration date fields to match the format seen on physical cards.
  5. Help users understand where they have been and where they are going in the mobile checkout flow by providing a progress indicator at each checkout step.
  6. Avoid displaying unnecessary and often redundant fields by setting the user’s ‘Billing Address’ to equal their ‘Shipping Address’ by default.
  7. Provide users the data they need to make an informed purchasing decision by providing the total order cost before seeking payment information.
  8. Help users distinguish between the order review and confirmation step by including a second ‘Place Order’ button at the top of the order review step.
  9. Avoid forcing users to retype duplicate information by asking for the same information only once during checkout and by reusing that information when necessary.
  10. Provide users with at least one third-party payment option, in particular if catering to international users.
