Amazon has added a new twist to Twitter that enables its affiliates who tweet about its products to include their affiliate information in the tweet so that they still get credited as the referrer.
Amazon explains how it works on its Amazon Associates blog:
Amazon Associates Now Integrates Directly with Twitter
We are excited to announce the launch of a new feature called Share on Twitter. You can access Share on Twitter from the Site Stripe and post links to your Twitter account from Amazon detail pages in just two clicks.
The Share on Twitter feature is easy to use. Simply log in to your Amazon Associates account and then visit any detail page on Amazon.com. By clicking on the Share on Twitter button in the Site Stripe, a new window will open and an Amazon-generated message is pre-populated in the 'What are you doing?' text area of your Twitter account (you may be asked to log in to your Twitter account). That message will include a shortened URL that already includes your Associates ID. You'll have the option to edit this message or simply hit the 'Update' button to post to your Twitter account. When Twitter users click on the link in your post and make a qualifying sale, you'll earn referral fees. That's it.
