Tap through the five steps and watch the gap between reported and real performance widen.
1
One account's conversion misfires
A tag double-fires, or a junk call clears the duration threshold, so one bad conversion enters the count.
2
Smart Bidding optimizes toward it
The algorithm treats the bad signal as a real outcome and starts chasing more of the same.
3
Pooled budget reallocates
Portfolio bid strategies and shared budgets spread the polluted signal across accounts instead of containing it.
4
The cross-account dashboard inflates
Small per-account errors stack into a portfolio-wide overstatement no single account view would reveal.
5
The client scales on noise
More budget goes to a number that was never real, and the mistake keeps compounding.
The recovery is loud: cleaning it up forces a relearn with weeks of depressed performance. Prevention beats it every time.
