ROAS

Return on advertising spend.

Divide how much revenue you made from your ad campaign by your campaign spend. Hopefully, that number is greater than one.

If the number is 0.99 or less, it is time to fire someone or wind down some contract because there is no way that it is your fault. You may also choose to add a multiplier, like 1.5, claiming that you could only track so much of the revenue, and the real number is higher by that notional amount.

Repeat that number in enough meetings until other people cite it themselves. By then, you will no longer shoulder the blame when someone invariably finds out about the ‘light’ fraud. You may well have also taken proactive measures and wound up heading to your next gig.
