Meta Cost per Outbound Click: Ad Traffic Efficiency

Measures how much you pay each time someone leaves Meta for your site—a key efficiency metric for traffic campaigns.

Formula

Meta Cost per Outbound Click = Meta Spend ÷ Meta Outbound Clicks

Formula Components

Metric	Definition
Meta Spend	Total amount billed by Meta for advertising during the period
Meta Outbound Clicks	Clicks on your ad that directed users to destinations outside Meta

Metadata
Type	Currency
Data Source	Meta Ads
Aggregation	Ratio

Example

Your traffic campaign spent $1,200 and generated 800 outbound clicks this week.

Metric	Value	Context
Meta Spend	$1,200	Weekly budget consumed
Outbound Clicks	800	Clicks leaving Meta
Cost per Outbound Click	$1.50	Acquisition cost per visitor

How It Works

Meta tracks clicks that send users away from Facebook or Instagram to external destinations like your website or app. This metric divides your total spend by those outbound clicks, giving you the true cost of driving traffic off-platform.
