CTR Calculator
Calculates the CTR of an ad and compares the CTR of two ads.
What to calculate
Formulas
- CTR = clicks / impressions × 100%.
- The difference in CTR between two ads is checked with a two-proportion z-test, the same one used in the A/B test calculator: the difference counts as proven if two identical ads would produce it by chance in fewer than 5 out of 100 cases.
