Coverage Potential ACR: Conversion Rate Improvement Opportunity

Coverage Potential ACR shows how much your attributed conversion rate could improve if you increase event coverage to the recommended goal.

Formula

Coverage Potential ACR = Coverage Gap × ACR Improvement Factor

Formula Components

Metric	Definition
Coverage Gap	Event Coverage Goal − Event Coverage
ACR Improvement Factor	Meta’s estimated conversion rate gain per coverage percentage point

Metadata
Type	Percentage
Data Source	Meta Ads
Aggregation	Average

Example

Your store currently has 72% event coverage but Meta recommends 95% for optimal matching. Coverage Potential ACR shows +4.8%.

Current State	Value	Impact
Event Coverage	72%	Below goal
Coverage Goal	95%	Meta recommended
Coverage Potential ACR	+4.8%	Potential ACR improvement

How It Works

Meta calculates how much additional conversion attribution you could gain by closing the gap between your current event coverage and the recommended goal. This improvement comes from more events having valid customer identifiers that Meta can match to ad interactions.
