Event Potential ACR: Conversion Rate Gains from Quality Fixes

Event Potential ACR shows how much your attributed conversion rate could improve by resolving event quality issues identified in diagnostics.

Formula

Event Potential ACR = Quality Issues × ACR Improvement Factor

Formula Components

Metric	Definition
Quality Issues	Event setup issues flagged in Diagnostics Count that reduce matching
ACR Improvement Factor	Meta’s estimated conversion rate gain from resolving each issue

How It Works

Meta analyzes event quality issues from your Conversions API setup and estimates how much attributed conversion rate you’re losing. Resolving these issues—such as fixing data formatting, adding missing parameters, or correcting event timing—enables better user matching and more accurate attribution.

When to Use

Scenario	Action
Prioritizing EMQ improvements	Focus on event quality if potential ACR gain is high
Comparing fix opportunities	Weigh event quality fixes against coverage improvements
Building the business case	Quantify revenue impact of resolving diagnostic issues
Tracking remediation progress	Monitor potential ACR decrease as issues are resolved

Metric	Relationship
ACR Percentage	Current attributed conversion rate this could improve
Diagnostics Count	Number of issues contributing to potential improvement
Coverage Potential ACR	Alternative improvement path through event coverage
