Sample size for the total campaign
On the overview report, you can see the total sample size for your campaign. Sample size is the amount of people in our panel exposed to the campaign. Unless the campaign target group is very small, the sample size will typically be in the thousands.
Sample size for part of the campaign
In addition, sample size can also be viewed for part of the campaign by looking at individual tracking pixels. In this case, sample size is the amount of people exposed to the tracking pixel. Unless, it is a very small campaign or a very narrowly defined target group, the sample size will typically be in hundreds.
Easily spot the tracking pixels with low sample sizes
As a special safety feature, the new AudienceReport automatically alerts the users attention to a low sample size. The N tab at the individual tracking pixel will be yellow, if the sample size is close to a very small size, and red if the sample size is critically low or zero.
