The Problem
Why accurate GA4 and pixel tracking matters.
Most brands run with tracking that was set up once, never audited, and breaks silently every time a CMS updates or a browser changes its rules.
Broken pixels waste ad spend
Every day with a misfiring Meta Pixel or GA4 event means ad algorithms optimize on corrupted data. You're paying for conversions that never get attributed correctly.
Wrong data drives bad decisions
If your GA4 shows 200 conversions but you actually got 140, your entire marketing strategy is built on fiction. Every channel allocation, budget decision, and ROAS calculation is off.
iOS and ad blockers create blind spots
Up to 40% of conversions go untracked in a standard client-side setup. iPhone users, privacy browsers, and ad blocker users are invisible to your analytics.
