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
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. Learn how to Target ads to geographic locations.
Negative targeting
Exclusions can be helpful if you have brand safety concerns. However, adding too many exclusions may limit or prevent your ad from serving (for example, excluding "youtube.com" or a remarketing list that contains most of your users).
Products
If your campaign is targeting only a few products, it may not be able to serve. Learn how to Manage a Shopping campaign with product groups.
For campaigns targeting local store visits and promotions, offline ads are primarily generated based on the store locations provided in the campaign. If no store locations are synced in the campaign, ads can't be created on the backend and the campaign won’t be able to serve. Check the campaign’s Settings > Store locations section to ensure locations have been successfully added to the campaign.
