Jagasoft, a lot would depend on what your budget is, but as Joe stated above, targeted traffic (the one that counts), is not cheap yet most effective. If you have a budget of $100 per month, then it is still worth spending it on targeted advertising rather than falling for 250,000 targeted visitors for $39 scams. Real targeted traffic, the one you achieve through search engines, specialized categories, cost a lot, but at least you market your web site correctly.
Best,
