Calculate how many impressions your budget can buy, or how much budget you need for your target reach
Impressions = (Budget ÷ CPM) × 1,000
An impression is counted each time your ad is shown to a user. It doesn't matter whether the user interacts with the ad or not - if it appears on their screen, it counts as one impression. Impressions are a fundamental metric for measuring the reach and visibility of your advertising campaigns.
