What is an Ad Impression?
Ad impression refers to the visual display of an advertisement on the Internet, such as a banner. This insertion usually takes place via AdServer. These record the number, time and repetition frequency of the ad insertion. The ad server logs the number of hits and evaluates them as measurable ad media contacts. An ad impression is also referred to as an ad view since it is purely a visual contact with the advertising medium.
Price per thousand contacts
Advertisements are usually billed according to the thousand contact price, or CPM for short. In English also Thousand Ad Impressions (TAI) or Cost-per-Mille (CPM). It is an amount of money that must be used to let 1000 people see the advertisement. The price for 1000 visual contacts with the advertisement is the thousand contact price. Whoever wants to place an advertisement usually pays a thousand contact price. There are also other payment methods without volume limitation, which take conversions as a yardstick.
The difference to Page Impression
The Ad Impression should not be confused with the Page Impression. Page Impression is the contact with the page itself. If there are two advertisements on the page, this results in two ad impressions for a one-page impression. Even if the page has only one banner, it does not have to come automatically to only one impression for a certain advertisement. Many banners change several ads per call. Or the banner changes the advertisement while the visitor is still on the page.
What are ad impressions for?
With the Ad Impression, online advertising can be easily traced. By evaluating the contacts that an advertisement has made, it is possible to see how effective the advertising location is. The reach of the advertisement can be estimated and it can be judged how many people have perceived the advertisement. However, this cannot be said exactly. The ad impression cannot be used to determine beyond doubt whether the user actually had eye contact with the advertisement, how he reacted to the advertisement and whether there was any interaction with the advertisement or the advertised object. Many visitors also use ad blockers, which prevent banner advertising. This would not result in an ad impression despite a visit to the site.
