Our FaQtor Test combines the best of A/B and multivariate testing with none of the downsides. By using fractional factorial design, we create a test matrix based on a strategic sample of list/offer/creative combinations. We then test these combinations at sample volumes so we can measure which variables have the biggest relative impact on campaign performance. We’re then able to predict how every combination would fare in a full-scale multivariate test. This allows you to see winning results of combinations you didn’t test and avoid testing a bunch of losers. In other words, it saves you a lot of money and delivers much faster results.
