What is Click Fraud ?

In online advertising, advertisers often use ad-networks to place a clickable advertisement on a publisher’s website. A user interested in the advertisement clicks on it to get more information. The advertiser then pays a predetermined amount of money to the publisher through the ad-network. This type of advertising is also called Pay Per Click advertising or PPC advertising, as the money as advertiser pays to the publisher is directly related to the number of clicks generated from the website of the publisher.
