The Amazon affiliate program has launched Amazon Widgets, which are “small, visually dynamic, easily configurable tools that allow you to feature products from Amazon on your website, blog or social networking pages.”
In as little as one minute, affiliates can populate a widget with their favorite Amazon products, their comments about those products, etc., and select from a set of color and layout themes to match both their mood and website.
Widgets are an extension to the classic Amazon affiliate link offerings, and as with other Amazon link formats, you can earn referral fees of up to 10% with the widgets.
My favorite is the Product Cloud Widget, which shows clusters of product titles that are relevant to your page. The font size of the title in the cloud indicates how relevant the product is to your page â€“ the larger the title, the more closely the product should match the topics on your page.
This is a good widget for sites with frequently changing content like blog pages, as it dynamically updates for relevancy.
