I had written this script a few days back and it has proven very useful for all my affiliate marketing efforts.

You need this script if you are an Affiliate Marketer and want to promote several affiliate products using the same landing page. This script opens up one affiliate link at a time in a full page iframe and rotates the affiliate links alternatively. So if you have three affiliate links to promote, the first user to your landing page will see the first affiliate link, the second user sees the second URL and so on. You can also dynamically change the TITLE tags of your landing page.
