Like other social media ads and digital marketing formats, A/B testing is a great way to test out the effectiveness of your Tik Tok ads. You can also find out if there is room for improvement. Upon deciding on a measurable target (e.g. CTR or Video views), you should produce two sets of ads with varying variables and see which one gives the best results.
To conduct A/B testing properly, you should only change one variable at a time and keep everything else the same for your two sets of ads. Sample size and length of time should also be considered, as they also shed light on important information about the performance of your ad.
