Something I've been doing for a while is using my Amazon Associates feeds in the "RSS Feed" sidebar widget. This allows me to create an automatically updating list of bestselling products relevant to the lens topic, and hopefully make some sales.
So, how exactly do you create Amazon RSS feeds and tag them with your affiliate ID? Let's start with an example:
http://www.amazon.com/rss/bestsellers/1048424/?tag=yourtag-20
You need to customize the following parts of the URL:
- 1048424 is the Browse Node, which describes what group of products you are promoting. You can get it from the Amazon URL when browsing a department or a sub-department:
- yourtag-20 is obviously your Amazon Associates tracking ID. Don't forget to add it at the end of the link, so the sales are credited to your account.
