Many people believe that all traffic should be free, but this isn’t always true. It can be worth it to pursue paid traffic avenues if you have a product that has been proven to convert very well. The trouble is, you will need some free traffic in order to test conversions, first.
I use one main rule of thumb when deciding whether or not to try paid traffic:
• If I am selling a product of my own, or if I am sending traffic to a page that focuses on selling on specific product, I will try paid traffic.
This means that I WOULD send paid traffic to a sales page or a review page, but I would NOT send paid traffic to a blog, forum, article directory, or other information-‐style website.
Paid traffic should be reserved for situations where you are promoting something very specific that has already been proven to convert. Otherwise, stick with free traffic.
