Ok this is really only good for Local businesses but my buddy did it with a flawless reaction. He owned a laser tag place about a block from a movie theater and he ran his commercial before the movies. This cost him about $150 a week, which is kind of a chunk of change but it brought in about $10,000 a week in new business. Just and idea i figured i would share to you all.
Myspace marketing was once a great way for PR and SERPS but now they have a URL shortener that kills your direct links. You were able to blast comments and get an insane amount of back links daily but they killed it. IT is down but not gone. If you have a site that can be fueled by direct traffic like image uploaders or a cool content site that needs pure viewers to spread then it is still perfect. So SEO and PR pointless, traffic and spreadable content = Gold.
People take this shrewd piece of information as fact and it is pretty absurd. Some people think by giving external links that it hurts their own PR. External links from your site has nothing to do with your PR. If you have 10 external links on a PR5 site you are dividing the PR you send out by 10. If you give a hundred links you are dividing it by 100. Yet this does not harm your PR, you are not giving yours away, you use your clout to vote for other sites. Nothing more. so by having more links your vote does not count as high but you do not hurt yourself in anyway. You could trade 10,000 links and still have great PR, your site would be full of crap and look bad but it would hurt you none..
