While targeting settings help you find the right set of users most interested in your business, each time you add targeting or if you have issues with your remarketing lists, you narrow the potential reach of your ads.
What you can do
Audience targeting
The amount of users on the list is below our requirements, so the campaign doesn’t serve. This only applies to App campaigns for engagement (ACe).
Location targeting
Targeting one postal code, a small radius, or a city with a low population may limit your campaign’s reach or prevent it from serving. Add additional locations to your targeting.
Negative targeting
Exclusions can be helpful if you have brand safety concerns. However, excluding all account-level content labels or, in case of ACe campaigns, remarketing lists containing most of your users may limit or prevent your ads from serving.
