When I click "promote" in Clickbank and then I enter my Affiliate ID, I get my affiliate URL. Each time I do this, I get a different URL. Does this affect my previous URLs? For example, if I get a URL and then I get a second URL, does this "break" the first URL and make me lose any sales?
As long as your affiliate ID appears at the bottom on the vendor's order page everything should be fine.
It's done like that on purpose. Otherwise it would be easy to reverse engineer the link and find out your clickbank id.
I never checked out for my affiliate link on the vendor's sales page. I will do that from now on. Thank you.
Yes, whenever you get a new affiliate url just check out whether your affiliate id appears below the vendors order page.
