What is the evidence for all those claims? I don't see anything. Can we see any research or proof each method improved the conversion?
Actually I wanted to ask the same questions - I work in Ecommerce day and night. What are these backed up by?
Many of these came from form design usability studies (some from Luke Wroblewski's work) e.g. permanent labels on input fields, descriptive CTA buttons. Other than #6, most of them are mobile form usability recommendations that I've seen cited elsewhere. As I'm working on digital payments myself, I've also come across this great research treasure trove on E-commerce usability studies: https://baymard.com/ux-benchmark.
What I'm curious about is the rationale for #6 to build trust (security icons and badges). Is that something contextual to the geographic area where you operate or because your product doesn't have enough brand recognition and therefore, brand equity yet?
Every day we make digital payments on different apps and websites. Most of the business in today’s world rely on digital payments. There are 100s of companies in the Fintech space working towards making digital payments more accessible, seamless, trustworthy and reliable.
In the midst of all the innovation and evolution around digital payments, in my experience, most of the apps and websites miss nailing the last mile of the user's experience of making a digital payment.
The difference between good and great is attention to detail.
I've listed down such small design details and interaction that makes a good experience, great.
This is by no means a comprehensive list. I will keep adding more. If you want to contribute, you can reach me at @designaive
