If you already own a website or a blog, then you can look for vendors that offer related but noncompeting products. Stick to familiar products and brands as they’re easier to sell. You can promote these products through 1. Placing a simple text or graphical ads in your site; 2. Create a dedicated sales page or web site to promote a particular product; 3. Include links to purchase products you reviewed or recommended in a blog, discussion forum or in the mailing list you have.
