The Clickbank Marketplace makes it easy for affiliates to find your product, format their affiliate link and start promotions immediately. That same ‘ease’ of affiliation is also a good reason NOT to use Clickbank as a merchant.
I've used Clickbank to promote my book, “The Super Affiliate Handbook: How I Made $436,797 in One Year Selling Other Peoples' Stuff Online" since it was first published in May 2003.
The built-in affiliate program was primary reason I chose Clickbank over other third-party payment processors.

That same 'ease' of affiliation is also a good reason NOT to use Clickbank as a merchant.
Clickbank merchants have no control over who may and may not promote their products.
Worse, it is sometimes impossible for Clickbank merchants to identify or contact individual affiliates.
For example, I recently came across an affiliate making false promises to promote the Super Affiliate Handbook. (See the screen capture below and note the use of the ® registered trademark symbol.) Moreover, the affiliate is using Google Adwords to advertise as well.

Goodness knows, that at NO time would I ever promise potential Handbook customers that they can 'start making money in 2 days' as affiliate marketers. That may be possible for some readers - but not probable for most - especially considering it takes most people more than 2 days to read a book that is 324 pages long.
So, what is a merchant to do if they find a Clickbank affiliate who 'breaks the rules'?
Well, here are a few options:
As you can see, hope runs low to correct the error if you are using Clickbank.
My recommendation: If your product might inspire affiliates to make false and outrageous claims - forget Clickbank.
Promote your product through Brian Littleton's ShareaSale.com affiliate network. ShareaSale has MORE than proven itself as both an affiliate- AND merchant-friendly network.
