The second pitfall is generating too high expectations regarding the performance of the winning variant of the test. Due to a statistical effect called regression towards the mean , the performance of the better performing option may not be as valuable as it was during the test. To put it simply, the winning variant could get this title not only because it was really. Much better than the other one, but also because it was simply more 'lucky'. His streak ends and his performance begins to decline. Do we have an alternative to A/B testing? Of phone number list course! The world of website optimization has a very wide range of use cases, and only some of them are suitable for A/B testing. Let's assume that you are conductin. A test on a website that has been functioning well for a long time, and the change you want to make is to be permanent and feasible for all users, also in the long run after the test is completed. In such a situation, it is important to perform a thorough comparison of the performance of the two variations, which is often simply impossible.
