Random and unique traffic is good to any site but getting targetted traffic is what makes the difference. This kind of traffic yields the highest conversion which would determine your site's success. Given a budget, I would always opt for PPC. PPC is a very effective way of getting targetted traffic given the proper treatment. Identify your niche and select the market you want to cater to and start from there. Research also on the keywords your desired market would most likely be looking for. IMO, one should be more focused on getting targetted traffic than just page views. Buying targetted link backs are also effective at getting targetted traffic. It really all boils down to what your site offers to your traffic
