What does Vendor Presence mean? Can I promote left vendors? How do I look only for existing/left vendors?
After some time, some vendors decide to stop using ClickBank. They close their website or change the processor of their payments. After a while, ClickBank notices their inactivity and removes them from the ClickBank Marketplace.
However, it does not always mean that you can not promote left vendors. If a vendor's website is up and running, ClickBank is used to accept payments and your hoplink is still active, everything is fine. But you should check this regularly.
There is a filter 'Vendor Presence' inside the 'Filters' control. By default its state is 'Existing Vendors'. But, if for some reason you want to find only left vendors, change this filter to 'Left Vendors'.
