Let Us Go Through ABCs of A/B Testing of Websites

Online business or the brick-n-mortar stores has website. You already have an existing website delivering modest traffic and you want to find what if I changed my website or some elements of website? Will it impact traffic to my website or the conversion rate? And if yes then how? Will the traffic/conversion rate be more than current rate or less?
To find out these answers, there is a very simple method followed, some call it scientific but there is not much science involved in it. Consider an example, in case of child, a mother knows that her child likes sandwich. Every day she packs his lunchbox with two Jam & Cheese sandwich, now she want to know, what if she packs Vegetable sandwich. Will her child eat? So as they say, mother knows it all, she packs lunchbox with one Jam & Cheese S/W and one Vegetable S/W. When the child returns back home, if she finds Vegetable S/W left in the box, she will come to know that only Jam Cheese is preferred and not vegetables. This same methodology or the experiment is applied to large number of children, to find out the eating preferences of particular age of children. This method is used widely in Marketing as depending on the results, marketing campaigns are formulated and even redesigned.

Coming back to Website, same sandwich concept is applied and it is called as A/B Testing. Statistician call it “Hypothesis Testing” …but let us stick to our “Sandwich Testing”. Thus the aim of A/B testing is same for website to find out what will be the outcome, if I made some changes in my website? And I want to know the result of the outcome because depending on the result I will optimize my site with new changes, as I cannot afford to lose the quantity and quality of my traffic. Here A and B are nothing but variant A and variant B – Jam & Cheese S/W and Vegetable S/W. It is one of the easiest way to increase traffic to your website, increase in ROI, and ultimately increase in conversion rates. It also updates us about what our viewers like and make us understand our audience better.

 A-Btesting

Above picture shows A/B testing. Variant A is tested against variant B.

Consider your existing website element as variant A and new website element as variant B.

Based on the customer data, you split the online traffic in to two, one set of the customers will be able to continue experiencing variant A and other set will experience variant B.

After splitting, your job is to observe and monitor the customer behavior where the change is introduced i.e. variant B and find out whether it yields increase in conversion rate?
