The 3x3 Experiment

After loading these regions and versions into GWO, you turn on the test. Each visitor will randomly experience one of the nine different homepage combinations (3 x 3). GWO will keep each visitor in that specific treatment for that entire visit and subsequent visits so users won’t experience any inconsistencies while they surf. For visitors without JavaScript, the testing platform serves the current version of the page. GWO tracks which tested treatments produce the highest conversion rates. It provides statistical confidence intervals on its results. It also parcels out the contribution from each tested region.
