What is a click through rate (ctr)?
Click-through rate (CTR) measures how often an impression results in a click. It is commonly used for search results, paid ads, email links and other placements. Compare CTR only across clearly defined channels and reporting periods because impression and click definitions can differ between platforms.
Formula and calculation method
CTR (%) = clicks ÷ impressions × 100. Impressions must be greater than zero.
