How Is Click Fraud Measured

click fraud

[mwoolgar]

We have been experiencing a large number of clicks on our ads but no conversions. Normally we do have a good conversion rate. Nothing has changed in our ads and then all of a sudden over the last two weeks our budget has started to run out. I have my suspicions that one of our competitors is clicking on our ads.

Can someone tell me how exactly click fraud is measured. There is the obvious click fraud that can be measured - multiple clicks from the same keyword and from the same ip address. However, what if someone has a list of 50 keywords and enters them over a day? How do you track these events? Even if the keywords were slightly different e.g. investing, new investing..
