Click-Through-Rate (CTR)

The Click-Through Rate (CTR) is a crucial metric in online marketing. It measures how often individuals, upon seeing an advert or a link, click on it to learn more. In simple terms: if an advert has been seen 1000 times (impressions) and 20 individuals have clicked on it, the CTR stands at 2%.

Calculation: Number of clicks (20) / Total number of impressions (1000)

The CTR is a key indicator of the performance of an advertising campaign, especially when it is billed based on the Cost-per-Click (CPC) model.
