Yes, you will need to add Google as a search provider, add your query string, and keywords - especially if you want to monitor and track which keywords are presenting the highest threat to your account. Remember, in addition to content network fraud, there is also competitor fraud - and your competitors are those who compete for ad position on the same keywords that you target in your campaigns.
I'll have Paul Leury, the Director of the Click Fraud Network, contact you directly and ensure your account is setup properly.
Thanks for joining the Click Fraud Network!
