Does this sound familiar?
GA4 is set up but I don't trust the numbers
Misconfigured events, missing ecommerce data, broken attribution — if you're not confident in the data, you shouldn't be scaling on it.
My agency says tracking is fine. I'm not so sure.
Tracking is invisible and easy to deprioritize. Most agencies focus on media buying — nobody's watching your data layer.
We've seen this across dozens of ad accounts. The tracking layer is always the last thing fixed — and the first thing that kills performance.
We don't run your ads.
We make sure your data is telling the truth.
