Any recommendations which service to use for classical, traditional AB testing with an even split of traffic between variations?
I used Experimentor app in Shopify and though I selected an even split of traffic, 50% traffic to old variation and 50% traffic to new variation, the results did not show even traffic allocation between the two variations.
Apparently, Optimizely and Convertize do not ensure even traffic allocation as well. Both Optimizely and Convertize support team cannot guarantee that.
If anyone knows of one service that can ensure that, I would like to know!
