I have two questions: 1 - What kind of info products people are buying the most on the web? Money related? SEO? Health Care? Weight loss systems? PUA stuff? - Please share with us the products categories you sell the most and give the names if you don't mind. 2 - What are the best sites and techniques to advertise them for free? An example: Publish a simple previewed followed by the product's link on a facebook group.
