E-commerce platforms are built to convert, and promotional content is a legitimate and proven tool for driving purchase behavior. The challenge is not promotion itself. It is promotional architecture.
Temu's mobile app surfaces promotional content at every stage of the purchase flow simultaneously, from entry overlays through to checkout. When promotion competes with navigation at every step rather than supporting it, the result is increased cognitive load, slower task completion, and higher abandonment rates, particularly among users with ADHD, dyslexia, visual processing differences, or limited technical literacy.
The design question this project set out to answer was not whether to include promotion, but how to structure it so that business goals and user goals are not working against each other.
