What causes this error?

The combined targeting criteria you’ve set (age, gender, interests, behaviors, location, device, etc.) result in an estimated audience size that is too small for TikTok to serve ads effectively.

How to fix it

Broaden at least one targeting dimension. Remove or widen interest categories, expand your location radius, include more age ranges, or switch from specific device targeting to ‘All’. TikTok’s UI will show estimated audience size—aim for at least 10,000+ people.
