Solution

Build a new user flow with new components

Interface type

Responsive website

Project status

AB testing roadmap

Methodology

1.

Research

Content square analysis

Up sell models benchmarks

Litterature and external studies gathering (focus on upsell methods)

“Up sell levers and user frustration” matrix creation

2.

Frame

Initial problematic refinment

Proposition of a new ancillaries categorisation (based on ancillaries common caracteristics. Not only on conversion objectives)

Single page for extra with three accordions components

UX writing proposal: better price justification and avoid relying on tooltips

3.

Design & test

Mockups

Interactive prototype with AI (mobile and desktop)

+50 qualitative tests (mobile and desktop)

KPI LOADING

until 2027

Next steps

AB test the new ancillaries flow

Test the accordion components and ux writing impact on conversion

AB test upsell levers one by one

Assess user’s tolerance to frustration and impact on conversion

AB test up sell levers combinations

The initial “up sell levers vs. user frustration” matrix will evolve depending on these results
