Data Quality Metrics | Upstack Documentation

Data Quality metrics measure how well your tracking setup is performing—specifically Meta’s Event Match Quality (EMQ) scores that determine how accurately your conversion events match to Facebook users. Higher quality scores mean better ad targeting, more accurate attribution, and improved campaign performance.
