How Click Fraud Works: Inside a Fraud Operation 

Forget the picture of one frustrated competitor clicking your ad 50 times Click fraud nowadays resembles a mini-business, and takes many forms that most advertisers don’t even know about 

There are two kinds of click fraud: real people’s and bot-driven fraud Real human activity is easy Click farms hire employees to click on ads and download apps all day Your competitors click your ads only to waste your budget In incent fraud, users earn some points for clicking ads, they click to earn the reward but not to become your customer 

Bot fraud is much more sophisticated: some bots disguise junk websites as premium ones in order to make advertisers pay extra for poor-quality traffic (domain spoofing) Some mimic perfectly human behavior, scroll the webpage, click ads and spend time on them (headless browser bots) Some take credit for app installations by sending a spoofed click before the installation Botnets distribute clicks from a great number of infected devices in order to simulate real user activity  

Bots today constitute 37% of all web traffic, and have been doing it for six years straight. Many masks, one plan This is the structure of a typical operation 

Why Click Fraud Goes Undetected

Advertisers’ fraud detection filters were developed five years ago. Today’s fraud knows all about them.
