You're spending real money on ads. But GA4 says one number, Google Ads says another, Meta says a third, and your CRM doesn't match any of them. So your team picks whichever numbers and attributions that support the decision they already wanted to make — and calls it "data-driven."
That's not a reporting problem. That's a measurement problem. I find what's actually causing the discrepancy and fix it. 100% success rate - Top 1% on Upwork. Rated by over 100 happy clients ⭐️⭐️⭐️⭐️⭐️

- Google Ads, Meta, GA4, and your CRM all show different conversion numbers — and you're spending five or six figures a month not knowing which one to believe
- You server-side tracking or Meta CAPI were 'set-up' , but the numbers still look wrong
- You don't leverage server-side tracking at all
- Your dashboards look polished, but you can't actually tell which channel is driving revenue
- A migration, redesign, or consent banner rollout quietly broke your tracking
- You're scaling paid media but don't trust the data enough to make confident budget calls

I work best with businesses that are past the basics — running real ad spend, dealing with real complexity, and needing someone who can diagnose and fix what's actually broken, not just install pixels. If you need the cheapest implementation or a quick tag drop, I'm probably not your guy. If that sounds like your situation, let's talk.

Every engagement starts with what I call The Tracking Diagnostic — a structured review of your full measurement chain: tags, triggers, consent, data layer, platform configs, server-side events. I map how everything connects (and where it doesn't).
You get a clear breakdown of what's broken, what it's costing you, and a prioritized fix plan — before any implementation begins.
