When Meta, your tracker, and your CRM all disagree
Broken tracking shows up as climbing CPAs, conversions firing late, and iOS traffic that looks unprofitable but isn't. It rarely shows up as an error: it shows up as decisions made on data that was wrong the whole time. Here's what it's really costing you.
Missed conversions

30 to 40% of conversions never get recorded
Ad blockers, Safari ITP, and iOS privacy settings silently drop client-side pixel events. Those conversions still happened, you just can't see them, and neither can your ad platform.
Weaker signals

2 to 3x higher CPAs from bad optimization data
When your ad platform sees fewer conversions than really happened, it thinks your campaigns are underperforming, raises your costs, and stops showing your ads to the people most likely to convert.
No attribution

No single number you can actually trust
You can see clicks. You can see conversions. But which click led to the highest-value customer? Which creative generates repeat buyers? Without post-click data, you're optimizing blind.
