From what I understand, this only needs to be placed on pages that have a clickbank payment options, such as on your sales page or any page that has a link to a clickbank order form. To me this means that it doesn't need to appear on any pages where I just have a link to someone else's clickbank product, because their sales page should contain the badge.
To get the CB badge, you'll need to log in to your clickbank account to get the code. Once logged in, you'll have the option of where the floating logo will appear on your page. You can find out more about it at:https://support.clickbank.com/entries/9 ... ust-Badge-
They do suggest putting it in the header section of your page, but I chose to place it lower down so that it doesn't slow down the page load speed. You can check it out in action on my sales page at: [Domain Private]
It appears on the bottom left-hand corner, which I don't really like. But that's the best option for now.
Hope this helps and good luck,
