New clients often ask how are we confident we can pinpoint the right audience for their ads.  I show them the 5 methods we use to find their audience, which of course leads to the question "can we use them all".  

This depends on the size of the audience.

In any data gathering, if the sample size is too small, you won't get meaningful data.  Meaning we will be showing your ad to people who aren't interested or missing people who are.

if your target audience is mothers of junior high football players in Cobb County, the audience size might be too small for us to decide if an ad or landing page is working. 

For my 30K in 30 Days campaigns, the audience - mothers of junior high football players in Cobb County- may be too small to show the ad 30,000 times in 30 days.

If the audience is small, it might be best to show the ad to ALL the people in a geographic area and let the right audience raise their hands signifying interest.

We create the ad image and copy to appeal to only mothers of junior high football players in Cobb County and when people start responding, use THAT data for a more specific next step.
