Cost Per Impression Definition

A cost per impression is a metric used to describe the cost to receive one impression. This is most often used in relation to marketing and the "impression" of an advertisement. Impressions are defined as when a person sees an advertisement for at least 1 second.

Example Calculation 1

Let's assume the following values:

Total Cost = $500
Number of Impressions = 100,000

Using the formula:

\[ CPI = \frac{500}{100000} = 0.005 \]

The cost per impression is $0.005 per impression.

Example Calculation 2

Let's assume the following values:

Total Cost = $1200
Number of Impressions = 300,000

Using the formula:

\[ CPI = \frac{1200}{300000} = 0.004 \]

The cost per impression is $0.004 per impression.
