The Amazon.com affiliate program has a neat tool I just found called the “Link Checker.”
This is exciting to me, because I’ve had concerns in the past that affiliate links that go through .htaccess redirects might not retain my affiliate ID.
The Link Checker tool enables you to paste your affiliate link and then load that link into a preview window.
Then you can click to check the link and there is a message indicating whether or not the link is tracking with your affiliate ID properly.
I think this is a great tool to provide affiliates with some peace of mind before launching a campaign, and I would love to see other affiliate programs and networks add this feature.
