Click fraud has become a major problem for online marketers. If you participate on Google adwords campaigns or Overture, you must already pay a lot for your campaigns.
What is click fraud?
Click fraud is the deliberate clicks to PPC search engine ads for completely other reasons than expressing interest for buying the related products or services.
Overture defines click fraud as clicks arising for reasons other than the good-faith intention of an Internet user to visit a web site to purchase goods or services or to obtain information.
Google defines click fraud, or invalid clicks, as any method used to artificially and/or maliciously generate clicks or page impressions.
In simple words, Click fraud means that someone is cheating you and that you pay too much for your pay per click campaigns.
