What is Cost Per Impression

[marsh]

Cost Per Impression is a SEM measuring-model based on performance. Just as in other media, the advertiser tries to speculate what the cost of the advertising campaign is based on the number of people who are exposed to it, with the Internet even more precise figures can be reached, often using the Cost Per Thousand (CPM) meter. The SEM campaign can then be valued per 1,000 impressions.
