What is CPM?

CPM (Cost Per Mille) is the price you pay for every 1,000 times your ad is shown. It's the most widely used metric for measuring the cost efficiency of an awareness campaign. Lower CPM means you're reaching more people for less money.

Worked Example

You spend $5,000 on a display campaign that delivers 1,000,000 impressions. CPM = ($5,000 ÷ 1,000,000) × 1,000 = $5.00. This means you paid $5 for every 1,000 times your banner was shown.

Engagement Rate

Engagement Rate shows what percentage of people who saw your ad interacted with it (liked, shared, commented, expanded, etc.). It's a measure of creative quality and audience relevance beyond passive viewing.

Frequency

Frequency measures how many times, on average, each unique person in your audience has seen your ad. Optimal frequency balances brand recall (too few = forgotten) against over-exposure and ad fatigue (too many = annoyance).

CTR

CTR (Click-Through Rate) measures how often people who see your ad actually click on it. A higher CTR indicates your creative and targeting are resonating well with your audience.

Viewability Rate

Viewability Rate measures the percentage of your ad impressions that were actually viewable — meaning at least 50% of the ad was on screen for at least 1 second (2 seconds for video). Paying for ads nobody sees is wasted budget.
