lol you're on the wrong board for that question. Mostly kids and dopes here. Try abestweb.com. But don't expect them to answer ya so readily. For the obvious reason. But, the serious affiliates advertise.
I have an amazon astore on my blog and my forum. I use the content posted on both of them to rank well in the search engines and drive traffic to the store. When I post a video on youtube, sometimes I will post a link to my store in the video description. The link is always on the first line of the description so its visible to the person watching the video. So I guess you could say that I market my store through content on my sites and video blogging.
I hope you're not one of them There's nothing wrong asking questions. You'll need to spend money on various marketing campaigns. Try PPC advertising on Google AdWords if you know the game, or hire a professional marketing agency to do so for you if you're not. You can also hire a freelancer to build backlinks for your online store too. Learn more from the link development & SEO section, there's a lot of things you should read here. Good luck.
