Scaling breaks weak foundations
At low volume, a slow or shaky tracker looks fine. The cracks only show when you scale, and by then the lost data and downtime are already costing you real money.
Slow redirects

Up to 500ms added to every click
Many trackers add 200 to 500ms per click at high volume. That latency costs conversions, every 100ms of delay measurably lowers conversion rate, and it compounds the more you scale.
Downtime

20 minutes offline during your best hour
A campaign goes viral, you scale a push buy to 500K clicks a day, or run a flash sale. The tracker goes down for 20 minutes. Those minutes cost thousands in lost data and revenue.
Data gaps

Silent losses that only show at volume
Conversions that fired but never recorded. Clicks tracked but stripped of attribution. Invisible at low volume, these gaps compound into thousands in unattributed revenue at scale.
