CTA Variation Test Group Size
Feb 26, 2017 2:05 PM
What have you seen as a good number of variations in a CTA Test Group? I've realized that I've underutilized this feature and ended up with many one-off designs for my CTAs.
So I've created on CTA Variation Test Group with 8 different images so we'll see how it goes.
I know that if the volume is high enough that you can make almost any size work but do you have any experience that shows that 2 or 3 or 4 or some other number is best for the test size?
