AmazoLinkenator will automatically (without any effort on your part) add your Amazon Affiliate code to 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.

The big advantage is that if you find an Amazon item that you want to include in a page and post, you don't need to do any extra steps to add your affiliate code. Just paste the Amazon 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!

URLs are affiliated only when posts/pages/comments are saved/updated/submitted. Any prior content will get the current affiliate code if it is re-saved.

All you need is a valid Amazon Affiliate Key; start here. The plugin doesn't check for a valid Amazon Affiliate key. Any URL affiliated will not be re-affiliated, and will stay the same.

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