The correct answer is C. click-through rate (CTR).
The click-through rate (CTR) is a metric used to measure the effectiveness of an online advertising campaign. It is calculated by dividing the number of clicks on an ad by the number of impressions, or the number of times the ad is shown. A high CTR indicates that an ad is relevant and engaging to users, while a low CTR suggests that the ad may need to be improved.
The impression rate is the percentage of people who saw an ad at least once. The view-through rate is the percentage of people who saw an ad and then took some action, such as visiting the advertiser’s website, within a certain period of time after seeing the ad. The stickiness ratio is the percentage of people who stay on a website for a certain amount of time after clicking on an ad.
CTR is the most important metric for online advertising because it directly measures the effectiveness of an ad. The other metrics are important, but they are not as directly related to the success of an ad campaign.
