Why you’ll likely get nothing from the Google click fraud settlement
ClickTracks has an interesting article that talks about the Google AdWords settlement and whether or not to participate. The short answer is that it’s not worth your time. They do a quick “back of the envelope” calculation to demonstrate how for all of the hassle you might have to go to receive advertising credits, you would receive on the order of $4.50 for every $1000 you have spent. There are many other variables that could increase or decrease this amount, but you can see that unless you have spent a considerable amount on AdWords, you’re unlikely to find that the refund justifies the effort.
