Fraudulent web click are friction in Google’s business. Fraudulent clicks ad costs to the system without a benefit to the performance of the system. Google’s profit is derived from improving the system (of finding customers for advertisers) and taking a cut of the profits that their system creates. Google makes a great deal of money because their system of matching advertisers with dollars to spend to customers. Google does this through ads on their search results pages and on third party web sites. Google engineers will do whatever they can to find ingenious ways to reduce that friction.
There have been many stories over the last few years about click-fraud. But none I have seen explain the simple idea that Google is the company with the most to gain by eliminating it (and Yahoo next). They often point to companies suing Google about fraudulent clicks instead.
Companies like Google run ads on web sites and charge the advertisers for each click (anywhere from a few pennies to several dollars for each click). Advertisers want to get potential customers when someone clicks on their ads, obviously they don’t want to pay when there is no chance the “visitor” is going to become a customer.
