Impression counts when something shows up on the visible part of the screen. When we search about the video and a video ad comes up in the search engine or video platform. Then counting of impressions will increase by one. Every time an ad is shown on the screen mobile/tablet/computer/Tv etc. will increase the impression number.
When someone clicks on that ad, the Click count increases. The final CTR will be calculated impression/click
