01 / DEFINITION & SIGNIFICANCE
Why CAPI matters for Universal Performance
Meta and Google server-to-server event transit delivering zero-latency lead data directly from the server, immune to iOS ad-blockers.
Browser pixels lose 20% to 35% of conversion events due to privacy blockers and cookie purging. CAPI dispatches events directly from your server, feeding accurate data to bidding algorithms.
02 / THE CALCULATION BLUEPRINT
How to track and calculate CAPI
Event Match Quality (EMQ) Score = Meta Algorithmic Data Score (Scale: 1.0 to 10.0)
EMQ Score = 8.6/10 (High rating with phone, email, client IP, and browser agent hashed) Tracking this metric systematically inside your analytics stack eliminates guesswork and aligns marketing spend with true business outcomes.
03 / INDUSTRY BENCHMARK MATRIX
