What is CTR ?

CTR or Click-Through Rate is a performance metric that shows how many times users clicked on an ad or a link. Marketers and advertising professionals typically use it to measure the success of search, display, and email marketing campaigns.

CTR measures the ratio of clicks to impressions of an ad or a campaign. Since most campaigns today are interactive and made to encourage meaningful engagement (signing up for a course, reading content, buying a book, etc.), CTR is good indicators of success with that goal.

Click-Through Rate is a good way to measure the quality of the ad for the audience segment, and can as such be used to measure the effectiveness of headlines, ad copy, meta descriptions, and other advertisement segments. If the ad creative resonated with the target audience, it is presumed (as is the truth in most cases) that the CTR will be higher.

CTR can also be compared to the conversion rate for further optimization of the sales funnel. If the CTR is high, but the number of conversions isn’t proportionate, marketers can presume that their product offer should be improved. Vice versa, if the number of conversions is extremely high as compared with the CTR, the ad copy would have to be optimized.

The formula for calculating CTR is;

CTR =  (Number of click-throughs/Number of impressions) X 100
