Hypothesis
Online buyers demand a frictionless shopping experience and any improvements that can help create those elevated experiences can also ultimately increase conversion rates and online store sales. This mobile checkout optimization experiment removes the manual steps a shopper has to take by automatically updating cart item quantities, thereby providing updated feedback to the shopper at all times.

THE EXPERIMENT IN ACTION
CONTROL – MOBILE
TREATMENT – MOBILE
What We Are Doing
We hid the traditional “Update Cart” button and implemented a treatment code that automatically refreshes item totals when a shopper changes the quantities of items in their cart.
Why We Are Doing It
A growing number of mainstream sites are implementing automatic cart updates to improve the mobile checkout experience. Removing the “update cart” button simplifies the process for shoppers as they make changes to their purchase and eliminates unnecessary distractions for those who aren’t.
ANALYSIS OF DATA
What We Discovered
Implementing the Automatic Cart Update produced a considerable lift on both desktop and mobile sales (5.34% and 6.25% respectively) and generally had positive results across the board.
What It Means
This experiment has a high likelihood of success for increasing online store sales for any given merchant. The stronger results on desktop also suggest that shoppers are more likely to edit their cart quantities on desktop than on mobile — the more modest lifts on tablets suggest that users benefit from the functionality, but don’t increase or change their item quantities as frequently.
The results revealed a gap in RPV lift between new and returning shoppers. Some returning shoppers may have expected to have to manually update their cart and became confused when the cart updated automatically. We see this type of friction lessening over time.
Things To Consider
While this experiment has a high success rate, merchants with a large percentage of returning visitors should pay special attention to the results for those visitors. Merchants who sell multiple units of the same products more frequently have a greater potential to benefit from this experiment but will want to keep an eye on their returning visitors as well.
WHO SHOULD USE IT
The Auto Cart Update Experiment is a great fit for merchants who currently only have manual update functionality on their cart page.
