Impression
Topic Overview[edit | edit source]
Impressions provide a measure of the number of potential viewers who have viewed a specific ad on a website or app. They're used in online advertising, which can be paid or free, like Google Ads, where advertisers pay for impressions. When used in conjunction with other metrics such as click-through rates (CTR), impressions can provide a useful gauge of how well an advertising campaign is performing.
How Impressions Work[edit | edit source]
Every time an ad is fetched from its source, and counted by the server, it's recorded as an impression. Impressions provide crucial data for calculating metrics such as CTR and cost per thousand impressions (CPM), which are vital in analyzing the effectiveness of online campaigns. Impressions are typically bought and sold on a CPM basis in the online advertising industry.
Usage Types[edit | edit source]
There are several ways impressions can be used and analyzed in digital marketing:
