Link Click-Through Rate (CTR) refers to the percentage of times people who saw your ad and performed a link click. It is a metric used to understand how interested people are in your ad/offer. 

 

To calculate Link Click-Through Rate (CTR), take the total number of link clicks divided by the number of impressions, multiply by 100%:

 

CTR = (Total Link Clicks / Total Impressions) x 100%

 

Generally, the higher the CTR the better because the higher your CTR, the lower your CPC. A good benchmark for eCommerce is a CTR of 1.50% or above.
