The Play: Step-by-Step

Step
1
Build an Anti-Persona Audience
Whether in Primer or externally, build a massive list of people to exclude: students, free users, <50-employee firms, irrelevant titles. Then load it into ad platforms. Make sure you enrich it with personal emails to get a good match rate.
Note: Primer can help with the list building and ensures match rates are 30–70%.
Exclusion AudienceSync That Audience to Meta Ad Account
Step
2
Sync Suppression List to Ad Accounts
Push to Meta, Google, LinkedIn. Status = “Ready” in 12-72 hours (once matching is complete). Don’t worry. Lists auto-refresh every week.
Step
3
Add as Exclusion in Retargeting Ad Sets
In each pixel-based ad set/campaign, include your pixel retargeting audience and then apply the anti-persona list under Exclusions.

4
Run for 2-3 Weeks, Then Compare
Check CPL, CTR, and on-site conversion events against the previous period for the same campaign. Overall lead volume may decline, but quality will go up.

Why It Works

Pixel = broad net. Anti-persona = tight fence.
Keeps algorithm learning on the right users; removes noise that drags down CPM and CVR.
High match rates ensure exclusions actually fire on social & display networks.
Use it when you want to trim fat — not muscle.
