Meta's algorithm is only as good as the data you feed it. Low match rate means Meta can't attribute conversions, can't optimize bidding, and spends your budget poorly.

Match rate minimums

  • Below 50%: Meta can't meaningfully optimize
  • 50-70%: Baseline acceptable
  • 70%+: Where real algorithm gains show up
  • 85%+: Enterprise-grade setup

The checklist

Server-side events via GTMServer or Stape. All seven recommended customer data fields sent. Deduplication via event_id. First-party dataenrichment (email + phone when available). Event Match Quality scoremonitored weekly.
