Guide: how to use A/B Test CTR Predictor
A/B tests are only useful if you know how long to run them and when a difference is real. Most creators end thumbnail tests early, on too few impressions, and act on noise. The A/B Test CTR Predictor scores up to four thumbnail concepts, gives each a winning probability, explains element by element what drives the prediction, and — crucially — tells you how long to run the real test and what difference counts as significant for your channel size.
