I have a brand new Rental Classified site that is free to post rental ads on, and I am looking to buy one or two premium links to help drive some traffic to the site. I'm wondering what link/s I should buy? I want the best bang for my buck and I am willing to spend maybe $50. Should I spend the whole $50 on one good link, or divide the money up and buy several cheaper links? If one just one link, what link? Thanks
