After 3000 impressions, ad A has a CTR of 2% and a conversion rate of 25%, and ad B has a CTR of 4% and a conversion rate of 10%. Which ad is better?

Answer: A

Step-by-step explanation:

3000 impressions

A CTR 2% conversion 25%

2% of 3000 = 2/100. 3000 = 60 clicks

25% of 60 = 25/100. 60 = 15

B CTR 4% conversion 10%

4% of 3000 = 4/100. 3000 = 120 clicks

10% of 60 = 10/100. 120 = 12

This way, A converted more than B
