AmazoLinkenator

Adds your Amazon Affiliate Link to all Amazon product links, in posts/pages/comments.

from CellarWeb.com

AmazoLinkenator will automatically (without any effort on your part) use your Amazon Affiliate code in any Amazon URLs. This will happen for pages, posts, and comments (depending on your settings below). Because you don't have to do anything special to affiliate a URL, this plugin is great for sites with lots of authors - especially those that might try to sneak in their Affiliate codes (which can deprive you of your Affiliate revenue).

And no special steps are needed for any Amazon link. Just paste the Amazon product link in the page/post, and Publish. Your Amazon Affiliate link will automatically be added to the product URL.

And AmazoLinkenator also works with any Amazon product links that your site commenters might add. If anyone includes a link in their comment that has their Amazon Affiliate code, it will be replaced with your affiliate code. All automatically! (It's your site, so you should get the Affiliate revenue!)

URLs are affiliated only when posts/pages/comments are saved/updated/submitted. Any prior content will have your affiliate code if it is re-saved. A counter on the Settings screen shows the number of times that your Affiliate code is inserted in Amazon URLs.

All you need is a valid Amazon Affiliate Key; start here. There is no check for a valid Amazon Affiliate key.

Plus, there's an option to automatically shorten the affiliate URL. This is great for 'hiding' your Amazon Affilliate link code. You just need a free Bit.ly Generic Access Token (start here). Use the Validate button below to for a valid Bit.ly API Key.
