As Affiliates... Do We Need To Buy What We Market?

Good question. My answer:

It would be obviously advantageous but not necessary.

Why? As affiliates, we're not selling but preselling.

Just do some basic research using the search engines and you'll find out many things about your affiliate product. Focus on what problems your target market is facing and how your product is a great solution. In your preselling, you present your findings like what the symptoms and signs of the problems are & the consequences if they are not identified early... Then, point them to your affiliate product as a great and plausible solution. Simply directing them will usually be sufficient since most people would appreciate the research you've done and put into one convenient place.

Read the above paragraph again if you will... I know you'll benefit from it =)

If you've bought and personally experienced the product, you can easily talk about the benefits and features of getting the affiliate product, but you may also overkill your preselling if you're not careful...

Personally, I usually get the product to find out more before I promote.
