An impression is a single instance of a digital advertisement being displayed on a webpage, in an application, or on a social media feed.
An impression is counted each time your ad appears on a user's screen. It's fundamental to measuring reach.
Impressions are the starting point for nearly all digital advertising analytics. They provide the basic measure of an ad campaign's size and reach, indicating how many times an ad has been put in front of a potential audience. By tracking impressions, advertisers can manage budget pacing, ensure their campaigns are delivering as planned, and calculate other essential performance metrics. Metrics like Click-Through Rate (CTR) and Conversion Rate are derived from impressions (Clicks ÷ Impressions = CTR). Without an accurate count of impressions, it is impossible to understand the relative performance of an ad creative or the efficiency of a campaign. For brand awareness objectives, the sheer volume of impressions is a key indicator of success, aiming to maximize exposure to the target audience.
