GLOSSARY DEFINITION • UNIVERSAL PERFORMANCE

Pixel & Server Event Deduplication (Event ID)

Passing identical event_id strings from both client browser and backend server so ad algorithms discard redundant conversion records.

Event ID FORMULA & STANDARD
Deduplication Accuracy (%) = (Single-Counted Conversions ÷ Total Ingested Events) × 100

(1,000 unique leads ÷ 2,000 paired events) × 100 = 100% deduplication accuracy

01 / DEFINITION & SIGNIFICANCE

Why Event ID matters for Universal Performance

Passing identical event_id strings from both client browser and backend server so ad algorithms discard redundant conversion records.

Sending both browser and server events without unique event_id deduplication double-counts conversions, artificially inflating reported ROAS and corrupting algorithmic optimization.

02 / THE CALCULATION BLUEPRINT

How to track and calculate Event ID

Deduplication Accuracy (%) = (Single-Counted Conversions ÷ Total Ingested Events) × 100

(1,000 unique leads ÷ 2,000 paired events) × 100 = 100% deduplication accuracy Tracking this metric systematically inside your analytics stack eliminates guesswork and aligns marketing spend with true business outcomes.
