What is click through rate? Click through rate is the number of people that click on a link vs the number of people that saw the link.
For example, if you sent out an email with a link to 5000 people, 4000 people open the email and read it. That means that 4000 people saw your link and let’s say 1000 people clicked on the link.
This is how the math is done. 1000/4000 = 0.25. This means that you have 0.25*100 = 25% click through rate.
