Click fraud

Whats the best software to use to protect against click fraud?

Google and the other search engines have pretty good systems in place to detect and protect against clickfraud.  They have billions of dollars invested into the reliability of their ad programs.  I wouldn't be overly concerned but you should definitely use analytics tools to monitor your data.  If you suspect clickfraud, definitely let the correct representatives know and they will investigate.. Google in particular has been very good at making reps more available to endusers even with lower adspend.

Click Fraud is much less of an issue today than it was a decade ago.  These companies have too much too lose if the reliability of the ad system were compromised.  They need to serve relevant ads to relevant searchers otherwise advertisers wont pay and the system would break.

If you are using any paid search services other than Google or Bing, I would strongly look into click fraud detection. The easiest way to do this is on your own end...

First, you want to make sure that it is a real user, not a bot. You can check the following...

1. Does the user carry a referrer?
2. Does the user accept cookies?
3. Does the user allow javascript?
4. Does the user allow flash?

The above are some simple tests - neither of them individually conclusive - that can test if it is a bot.

Secondly, you want to make sure it is not the same user over and over again, by tracking IP addresses.

Third, you should make sure that your clicks aren't being generated in small iframes or popunders - the easiest way to do this is with javascript and capturing the window size and/or whether self.window = top.window.

Fourth, you should track what users are doing once they reach your site. If your conversion rate is less than 1/10th of Google AdWords or Bing, you should be concerned.

You can always use a third party software like AdWatcher, which is pretty good. It can get buggy in large volumes though.

Good Luck.
