Click-Through Rate (CTR) is a metric used in digital advertising to measure the effectiveness of an advertisement.
CTR is calculated as the ratio of the number of clicks on an ad to the number of times the ad was shown, expressed as a percentage. This metric helps evaluate how well an ad captures users' attention and encourages interaction.
If an advertisement was shown 1000 times and received 50 clicks, the CTR would be:
CTR=(50/1000)×100%=5%
