New Amazon aStore
Instead of going through the time consuming process of adding individual Amazon links I went for the fairly new Amazon aStore.
Basically it creates all the store pages for you. For example I decided I wanted a page on Michael Jackson Posters, so I just search there products, clicked "Add" for each poster I wanted and its imported into the store. I then did the same for a number of other categories.
Then all I had to do was place the link in an iframe and the store page shows up on my own webpage, all nicely designed by myself to fit in with my colour scheme. Amazon itself doesn't actually let you know you can link to the individual categories you create, so I was pleased when I tried it that it worked and looks greats. Each of my individual pages shows the right products.
No doubt if I didn't have individual store pages created I would just link to the new astore index.
I also added a large block of store adds at the base of the index page. These are set to open the store in a new window and if anything looks better this way than my actual own store pages with the iframe.
Whether they increase salesonly time will tell. I'll be suure to keep you informed.
