Meta Outbound CTR measures the percentage of impressions that resulted in outbound clicks—the share of ad views that drove someone off Meta to your destination.
Meta Outbound CTR = ( Meta Outbound Clicks ÷ Meta Impressions ) × 100

Example
Your traffic campaign delivered 185,000 impressions and generated 3,145 outbound clicks in March:
| Ad Set | Impressions | Outbound Clicks | Outbound CTR |
|---|
| Prospecting - Lookalike | 95,000 | 1,900 | 2.00% |
| Retargeting - Cart Abandoners | 50,000 | 850 | 1.70% |
| Interest - Home Decor | 40,000 | 395 | 0.99% |
| Total | 185,000 | 3,145 | 1.70% |
How It Works
Outbound CTR counts only clicks that take users away from Meta properties (Facebook, Instagram, Messenger) to your external destination. This excludes in-platform interactions like reactions, comments, and profile visits. For campaigns optimized for website traffic, outbound CTR provides a clearer signal of ad effectiveness than overall CTR.
