Hi I'm looking into becoming an affiliate through Clickbank. My niche of choice is health products. I am working on a blog, where I will post valuable content like articles and "how-tos". How can I promote my affiliate stuff without making it look like a sales page? In other words: how can i presell the product through my articles? I've heard that many affiliates make the mistake of selling the affiliate product from their site, whenthey should presell instead. Any idea? Thank you for your time.
