There are numerous strategies to promote products. I suggest you read up some solid books on affiliate marketing. They gave me a clear view on what exactly should I do.
there are a ton of good guides out there. If you sign up for my affiliate news letter, you can get a copy of my www.DailyProfiting.com for free on day 2. you can sign up here www.beateczema.com/affiliates.html Hope this helps.
I recommend this one - http://www.thelazymarketer.com/ and http://www.desperatebuyersonly.com/ Both great ebooks. Follow the guides and (big AND) put the effort in, take some action and you can't fail to make a few bucks. Good luck
Tomorrow I am going to give away my 1 hour video course, this should really help. I can't put it in my signature yet because I don't have 7 posts, but when I do and it's done rendering, I'll add it.
