what is impression in twitter

Impressions on Twitter refer to the total number of times a tweet has been seen, including the times it appears in a followers timeline, search results, or as a result of someone liking the tweet. Impressions are not unique views, meaning that if one person sees a tweet five times, that counts as five impressions. Impressions are a valuable metric for measuring tweet performance and impact, as they provide insights into the total exposure a tweet has received. Impressions can be tracked by enabling Twitter's native tools and analytics for an account, and they are readily available to any Twitter account with a setting adjustment. The Tweet activity dashboard provides data about impressions, total engagement, engagement rate, follows, hashtag clicks, embedded media clicks, likes, link clicks, permalink clicks, replies, retweets, and shared via email.
