Audience Quality
What's a good Retargeting Pool Size?
A good Retargeting Pool Size for a local business is 5.0K or higher. Number of users in retargeting audiences. An excellent Retargeting Pool Size — the top tier Karbon Agency grades client campaigns against — is 50.0K or higher, while 500 marks the minimum acceptable tier.
The three tiers Karbon grades against
| Tier | Value | What it means |
|---|---|---|
| Minimum | 500 | The floor. Below this, something is broken. |
| Recommended | 5.0K | The tier a healthy campaign should hit. |
| Excellent | 50.0K | Top-tier performance worth defending. |
Higher is better for this metric.
Why Retargeting Pool Size matters
Retargeting is the highest-ROI audience. Below 500, platforms cannot optimize delivery. Above 5,000, you have a meaningful pool for segmented retargeting strategies.
