How Is the Click-Through Rate Calculated?
This is an indicator of a response to a specific email message, which is gauged by the percentage of recipients that decide to click a web link incorporated into the email message.
To define the click-through rate, divide the volume of opens/clicks by the number of emails dispatched (multiply this number by 100 to express the outcome as a percentage).
Example: 500 subscribers opened your email and 250 of those clicked on a link giving you a 50% click-through rate.
250/500 = 50%
Internet marketers usually benchmark their present click-through rate with past click-through percentages to evaluate if marketing efforts are strengthening.
