Markitech / Meta Ads AI Agent / Meta Audiences
Meta audiences that pull their weight
Custom audiences, lookalikes and exclusions, planned from your best signals.
Updated November 4, 2026 · Markitech team
With broad targeting and Advantage+ doing more of the work, audiences matter most as signals and exclusions.
Markitech plans the custom audiences, lookalikes and exclusions that match each campaign's goal, and checks in a real browser that the pixel events they depend on fire. You create the audiences in Ads Manager.
How to do it
- Review existing audiences and sizes.
- Build website custom audiences from key events.
- Build customer list audiences with hashed data.
- Create lookalikes from high-value customers.
- Apply exclusions for recent converters.
- Check overlap between ad sets.
Common mistakes
- Lookalikes from low-quality seed lists.
- No exclusions, so ads chase existing customers.
- Stale customer lists.
- Heavily overlapping ad sets competing with each other.
