Search Trends - Search Engine Marketing

A great post about click fraud over on SEOMoz this is actually part 2 in the series (see part 1). This guy talked to some of the guys from the "underground web" that are acutally making a lot of money from very questionable practices as search engine and contextual ad affiliates. I've been interested in the topic of click fraud for quite a while, and just today we had an incident where a client's YSM account racked up a ton of clicks for a single keyword that had previously not been clicked on. The results of the traffic: zero sales. Hmmm...smells like click fraud to me. Yahoo is supposed to be investigating, but chances are they'll come back and say it was valid traffic. I'm anxious to read the next posts in this series.
