spent $100,000 during the time period one would first need to determine and certify how much of that was affected by click fraud. Let's say one determines 10% or $10,000 in click fraud. One would then devide that by the revenue during that time period of about 11 billion which I think is .00009. One would then be eligible for .00009 x $60,000,000 or $5400. If the total claims are below $60,000,000 one would get $5400 in ad credits otherwise one would get a prorated amount?
Er, yes, except that the math is slightly wrong:
$100,000 x 10% = $10,000 $10,000 / $11,000,000,000 x $60,000,000 = $54.55 in Adwords credits
Yes, that's a whopping 0.055% of your Adwords spending.
