Final answer:
The metric that represents the number of times ads are displayed is 'impressions'. This is different from clicks, CTR, pageviews, and visits, which measure other aspects of user interaction and website traffic.
Step-by-step explanation:
The metric that shows the number of times your ads were displayed is e. Impressions. An impression is counted each time an ad is fetched and potentially seen by a user, regardless of whether the user interacts with the ad. Clicks refer to the actual interaction where a user clicks on an ad, while CTR (Click-Through Rate) is a ratio showing how often people who see your ad end up clicking it. Pageviews are the total number of pages viewed and visits are the number of individual sessions initiated by all visitors to a site. However, impressions are specifically used to count ad displays.
