What is A/B Testing

A/B testing lets you test and determine which of your 'improve performance' ideas actually produce the results you're after. The standard A/B test involves testing two variations, A and B, to determine which gives you the best results. Put simply, A/B testing splits your traffic into two equal halves, and sends half of your traffic to variation A and the other half to variation B. By comparing the results from each variation, you can conclude which version produces the best results.

A/B Testing - the Gold Standard

When evaluating new ideas and their impact on Ecommerce, you need to control for variability in multiple factors that affect outcomes. If you do not do this, you cannot reliably conclude what caused an observed outcome, and therefore understand with confidence, what actually improves your results.

Comparing ideas under the same conditions, at the same time, with the same audience controls for the factors you're not measuring or potentially aware of. This is the essence of A/B testing. It's the gold standard in understanding which changes produce repeatable improvements.
