A/B testing(show new feature only for 50% of users)

Question

I'am creating a new feature for my iOS app. After I publish the app I wants to show the new feature only for 50% of the users, so I can do some testing which version makes more orders. I have no idea how to do it without using some third parties like Optimizely. Also is it possible to do this using Google Tag Manager(GTM). So can someone please help me to figure this out.

Thank you very much for your time.:)

Answer 1

I finally figured out how to do the A/B testing with 'Google Tag Manager'(GTM). In GTM you can create a variable called 'Google Analytics Content Experiment'. With this variable you can select how many percentage of users going to see each Variation(your experiments). You can create up to 10 variations for single experiment.

GTM is so cool and powerful. GTM contains so many features that could save lot of time and I totally recommend it for anyone who is going to do A/B testing.
