I want to pursue this matter now, and I was wondering whether you can provide me with a little more details about the technical aspects of the report submission.

1. At what point do you consider a clicker as fraud, how many times does he have to click to be considered fraud.

2. Considering a certain threshold has been establish, do you include any click to any keyword, or only if its repeating within the same keyword.

3. What amount do you request back, avg cost of that keyword for that timeframe?

4. And last but not least, what about non aggressive clickers, lets say a particular user clicked 5 times, would you request back 4 out of the 5?

Your response, and hands on experience on this matter will be greatly appreciated, and I’m looking forward to share your expertise on this matter.

The click fraud detection you are using will catch the obvious stuff, which, for the most part, engines are getting better at catching. It won’t, however, do any good against the more sophisticated bot-based programs that use 1000’s of compromised PC’s to generate fraudulent clicks against networks of MFA sites. Google “clickbot.a” or “KMeth Worm” for more. These approaches will use multiple IP’s to generate clicks from different systems with different browser names. Impossible to detect. You will only see declining conversion. Simple answer? Watch contextual ads carefully or avoid them altogether and stick with mainline search.
