Click fraud is a black-hat
technique to artificially inflate the number of clicks on Pay Per Click advertising. The motivations of such black-hat ad clickers can be broken into two categories. First website owners selling PPC advertisements
wanting to increase their income from the ads on their site or, alternatively, competitors of the advertiser clicking on the ads in order to waste their advertising budget on useless clicks which will not create any leads. Click fraud is a significant challenge to identify and block since people clicking on ads are anonymous and techniques like deleting cookies and the use of VPN are quite simple.
