What is A/B Testing?

A/B Mobile testing should be a basic step in your mobile business strategy. Testing every aspect of your app or game and understanding what’s working and what’s not is vital in terms of Conversion Rate (store) and business (app). A/B testing consists of comparing elements variations to see which one drives more traffic and installs or generate, per example, more sales or subscriptions.

We can find two kinds of A/B testing: app stores A/B testing, on which we test the elements on the store listing / product page (such as textual fields like Title and Description, or visual elements like the screenshot gallery or video) and app A/B testing, on which we test the product.

In order to do the experiment, two different versions of the store listing are created with only one difference between them. It can be something visual, such as screenshots or the icon, or textual, like the title or the description. Then, the two versions are distributed among the audience equally and, when enough users go through it, we can determine which variable is performing better.

Why Do I Need A/B Testing?

If we want perfection for our app, we need constant work. Optimization is a never-ending process, and that includes experimenting with our elements to keep our app or game at its best. Moreover, by doing A/B testing we will have statistical confidence when it comes to deciding which changes to make.

For example, imagine that your mobile app or game includes IAPs. Thanks to A/B Testing you can check which banner, button or CTA (call to action) is performing better in terms of taps / sales. By knowing your users’ behavior it will be easier for you to implement variations and, therefore, to improve.

Another aspect to consider is that testing your app can also improve user retention. You may have an amazing app or game, but it could need some changes that would improve it significantly. Maybe there’s a button that would perform better in another location, or the text is not clear enough… Those little things can make users decide whether to stick to your app or game or to leave it.

How to Do A/B Testing

If it’s your first time with A/B Testing don’t worry, it’s quite simple. When you select your tool, think of something that you would like to test, like a title in the stores, a different app view design, a button… You name it!

This is the cycle you should follow when planning your A/B testing strategy:

  1. Brainstorm to define a hypothesis to see what needs to be tested
  2. Variants: Select the elements that are going to be tested
  3. Test: Split the audience and show them the two variations of the page
  4. Analyze the results to decide which variation performed better
  5. Apply the winning variant (or not, it’s up to you!)
  6. Keep testing. There’s always room for improvement and continuous tests will help you grow!
