Proba
Stop guessing which listing converts.
Statistically rigorous A/B testing for titles, images, and price — so every listing change is backed by real conversion data.
The problem
Sellers change images and prices on a hunch and never know whether it helped or hurt sales.
Our approach
Proba rotates variants on a schedule, measures conversion and revenue impact, and calls a winner with statistical confidence.
What it does

Revenue-aware results

Confidence scoring
