"I want to add some affiliate product links to my blog, but I don't know which products to choose?"
If you already have a niche or established website in a market, choosing the right affiliate products to promote is quite easy. There are a few things you should do to verify if it is a good product to promote or not:
1) How Well Is It Marketed?
Would YOU buy a product on the landing page of the product itself? Are they marketing it effectively?
2) Is the product any good?
Buy the product, test it out and make sure it is worth the price (refunds can be a bear).
3) Test out the affiliate link and program
Sign up for their affiliate product, go through their sales process, buy the product and confirm the commission, reporting and experience.
Follow these three steps and you should not go wrong!
