CTR

CTR, or click-through rate, is the rate, usually expressed as a percentage, calculated by dividing the number of clicks on a link, advertisement, or post by the number of times it is shown.

In plain English

It shows how often people click after something appears. The figure comes from dividing the number of clicks on a link, advertisement, or post by the number of times it was shown, and it is usually written as a percentage.

In context

In that ad-performance metric column, CTR reports the percentage rate calculated from clicks divided by impressions for the ad or post shown.

Core meaning

“In the ad report, CTR for the second post was lower than the first even though both had the same number of clicks.”
