Sometimes even the most reputable PPC search engines face the problem of fraudulent clicks. They put quite an effort into protecting their clients from click scam. Take Google, for example. About a month ago it acquired spider.io with the aim of improving efficiency of Google advertising. Spider.io is a quite successful fraud- fighting company: last year it discovered Chameleon – the botnet that caused 6.2 million advertising dollars to be wasted on bot clicks. Monthly.
Advertisers are the ones who suffer the most in this case. As networks get their profit even with malicious publisher websites, some of them don’t want to invest their time into fighting against click fraud. So how can you recognize the network that actually cares?
