Testing whether imagery helped the checkout experience

Problem: Customers were leaving partway through signing up, and it wasn't clear whether the graphics in the abandoned-cart flow were helping.
My role: I ran the A/B test with Marketing, comparing a plain graphic with a graphic that included imagery.
What I did: Set up the test and measured which version drove more people back into sign-up.
The result: The version with imagery performed better, by enough that we changed the abandoned-cart graphic to use it.
