I'm thinking about creating a site with comparisons of products within a niche. I want to advertise each product as an affiliate. However, I'm a little concern that companies won't accept me in their programs if I advertise their products along with products of other companies. Do you guys think there would be any problem by doing this?
You shouldn't have a problem with that. I have done similar things, I advertising competing products on the same page and even had a company rep look at one of my pages and said it was great. Reviewing and comparing is a great way to advertise. Of course, you don't want to trash one of the products you are promoting!
You will have no problem with this method. All of my affiliate sales are through Review Type Websites. Hydranetwork, CJ, LinkShare & Clickbank have never complained.
Thank you for your answers. It's good to hear you guys haven't experience any problem with this method. And I'm glad to hear this advertising method is great according to you.
