Which of the following formulas can be used to determine the cost per thousand impressions?

The formula to determine the cost per thousand impressions is based on the concept of calculating the cost associated with every thousand times an advertisement is displayed. The correct formula, which is represented in the answer choice, takes the total cost of the advertising and multiplies it by 1,000, then divides that product by the total number of impressions.

Using the formula (Cost x 1000) / Impressions directly tells you how much you would spend for every 1,000 impressions received. This creates a standardized measurement that allows advertisers to compare costs across different campaigns more easily, as it normalizes the cost to a common scale.

In contrast, other options either misrepresent the relationship between cost and impressions or do not utilize the correct multiplication and division necessary to arrive at the cost per thousand impressions. By focusing on scaling the cost based on impressions, the correct formula gives a clear picture of the efficiency and effectiveness of spending within a digital marketing framework.
