The $300 Million Dollar Button: IxD, UX, or UI?


#1

Hello,

Trying to understand how one might describe the famous $300 Million button case study.

Here’s the article : https://www.uie.com/articles/three_hund_million_button

Basically, a site increased their revenue by changing the language from Register to Continue in an ecommerce
checkout flow.

Is this an example of Interaction Design?
