How do you tell when someone is doing click fraud on your site?

Today I logged in and found a page of mine had 11 impressions, and 19 clicks! That doesn't seem right. I do have two ad banners, so maybe someone was looking at all of the ads? It just looks a little fishy.

Would this be a sign of click fraud, and how do you even protect against it?

Thanks,

try adlogger it will monitor ip adresses, you can then block IPs and so on.

 

Unfortunately the development of AdLogger has been put to a halt. Due to some recent changes in the Google AdSense program, AdLogger has been rendered inaccurate and useless. Despite the best efforts to circumvent these changes and maintain a high level of accuracy, our developers could not come up with a solution.
