Pixel + CAPI -- Your Server-Side Signal Stack

The browser pixel alone is broken. iOS 14.5 killed 30-50% of signal. Ad blockers take another 20-30%. Cookie deprecation is finishing the job.

The fix is Conversions API (CAPI) -- server-side event sending that runs parallel to the browser pixel, shares event IDs for deduplication, and passes hashed user data that browsers can't block.

This skill audits, sets up, tests, and optimizes your Meta Pixel + CAPI stack. Target: 9.3+ EMQ on Purchase, 8.0+ on Lead.
