Seems BMW was gaming the Google search engine and in turn Google gamed them back by giving them a page rank of zero which is a death blow. This blogs page rank hovers between six and seven everyone wants a high page rank but you only can achieve it by having great content. I get e-mail every day people asking to do a link exchange when I send them a rate card that shows it will cost them $50,000 per year to do a link exchange the quit bothering me. Many of these sites are nothing but link farms which are trying to get a higher page rank to achieve higher adsense revenue. [BBC]
It should be noted that everyone I link to on this site gets linked to for free except the advertisers of course.
