Markethealth is not a scam. The thing to be aware of is that when people are looking for a product in a health niche, it is a very specific need. So if you do affiliate marketing in health areas ,you want to be lazer focused. If you are into weight loss, you should only have 2 or 3 products. Preferably a cheap, middle and high ticket product.

If you are in the sleep niche you should only have one or two products. Basically you should have a separate website for each niche and be very specific with your products and information.

Information is the way that you will convince people to trust you enough to buy from you. Eliminate their pain and they will gladly pay you for it.
