Definition
Ad frequency is the average number of times one person saw your ad: impressions divided by reach.
Formula
Frequency = impressions / reachExample with made-up numbers: 100,000 impressions delivered to 40,000 people gives a frequency of 2.5.
How to use it
It is an average, so some people see the ad far more often than the number suggests. Read it together with results over time rather than against a fixed limit.
