A lot of people use their limited number of links on Hubpages, InfoBarrel, Wizzley, and other sites foolishly. They link to a single product, when each of these sites has a module or element to link to single products on Amazon. If the person is not going to buy from your element, they're not going to buy from your link. So never use a link to link to a single product.
The smart way to use your links, if you're going to link to Amazon as well as use the Amazon element is to use the links to link to a search page, a Listmania! list, a So You'd Like To guide, reviews, discussion forums, or anything at all on Amazon except a single product. The thing is, once you get the customer to Amazon, you can let Amazon do the selling. So get them there any way you can. You'll still get the credit for whatever they buy, using the "Link to this page" tool (see the previous post on how to do this) in your Site Stripe. By all means use the Amazon elements for single products but it's a waste to use links for that when you can direct them to a page where they can or want to buy more than one thing.
If you don't know how to create or find any of those things I listed above, then it's time you checked out the other kinds of information Amazon has available. Believe me, you want to learn, because this is where most of your sales will come from!
