How to run an A/B test with client votes (and a reason)
By the Usertack Team · July 9, 2026 · 3 min read
Short answer
Run a creative A/B decision by showing clients two directions and asking them to vote with a required reason. The reason turns a gut “I prefer B” into documented rationale, and the vote is logged like a sign-off so the decision sticks.
“Which do you prefer?” needs structure
Presenting two directions over email invites wishy-washy answers—or a committee that never decides. A structured vote forces a clear choice and, crucially, a reason behind it.
Make the reason mandatory
The reason is where the value is. “B, because it feels more premium and matches our packaging” tells you why, guides future work, and protects the decision later. On a review link, each voter picks a variant and must say why before the vote counts.
Log the decision like a sign-off
- •Show variant A and variant B side by side.
- •Each stakeholder votes and gives a reason.
- •The leading direction is recorded with the rationale.
- •The choice is captured as a logged decision.
Usertack's A/B review lets clients vote with a required reason and records the outcome as a certified decision, so a design direction is chosen on evidence—not the loudest voice in the room. It's part of the same feedback-to-sign-off flow.
