I've found a quick and easy method to make some sells.
Step 1: For this method you must infiltrade forums in your niche. If you are a vendor you don't want them to recognize you as the vendor. So pick a normal name and don't have a link in the signatur.
Step 2:Start posting and give away some content. Try to really position yourself as one of them.
Step 3: Lookout for people that are having problems.(which your product can solve). Especially problems that could not be solve with a quick forumpost.
Step 4: Just write this people a pm " Hey I've read your post. Sometime ago I've had the same problem, I was using method xyz and it really helped me out alot. (Affiliatelink)"
Step 5: Nothing more to do, just watch the money comin in.
20% of my PMs result in a sale. I'm doing this every day in 8 different forums. Unfortunatly there not always people with problems to solve and sometimes your product can't solve the problem. But this method is very very very profitable for me compared to the required time.
