Audience exclusions are as important as audience targeting. Excluding the wrong users
from your campaigns prevents wasted spend on traffic that will not convert.
High-Value Exclusions for Prospecting Campaigns
Existing customers:
Upload your customer email list as a Customer Match audience.
Exclude it from all prospecting campaigns.
Existing customers searching generic terms are not acquisition opportunities.
Recent converters:
Create a remarketing audience of users who converted in the last 30 days.
Exclude from campaigns targeting purchase intent.
They already purchased -- showing them the same acquisition ad wastes budget.
Low-quality audiences:
For B2B campaigns: Exclude in-market segments for consumer goods (irrelevant).
For high-consideration services: Exclude in-market audiences for quick/impulse purchases.
Exclusions in Remarketing Campaigns
Already seen the offer enough times:
Users who have seen your remarketing ad 10+ times without converting
have likely decided not to. Exclude them after a frequency threshold.
Churned users (beyond re-engagement window):
Users who last visited your site 180+ days ago are cold.
Either move them to a separate lower-bid campaign or exclude entirely.
How to Apply Exclusions
Campaign level: Campaign > Audiences > Exclusions > Add audience.
For Customer Match exclusions: Ensure the list has 1,000+ matched users to activate.
