Clickbank has a new promotion tracking enhancement that allows affiliates to add an 8-character tracking code to the hoplink and order process, which provides the ability to accurately track and manage your campaigns.
Key features of this enhancement are:
- Allows affiliates to add a code to the hoplink process for promotion tracking
- Captures promotion tracking code during the order process
- Displays the promotion tracking code in the transaction report(s)
So, if you sell an ebook by linking directly to the merchant from Google Adwords, on your site and through your newsletters, you can add an individual tid (tracking ID's) to each link.
For example, if you are selling the Super Affiliate Handbook, the link that goes out in your newsletter might look like:
http://yourid.merchantid.hop.clickbank.net/?tid=sahemail
Where as the affiliate link on your site could be:
http://yourid.merchantid.hop.clickbank.net/?tid=site
Happy tracking!
Cheers,

Is it true that ebook writers using an email capture box on their sales pages are ripping affiliates off when customers being sent to them sign up for the emails, then they sell them a book weeks or months later and we never see a dime for it. 
Hello from Carmel, CA., where I'm spending a few days on the tail-end of my Casino Affiliate Convention trip. As I live in the near-desert, it's a lovely change of pace to breathe fog and listen to the ocean.
