You can send them to an offer you may be promoting yourself. Or you can leave it blank and the buyer gets them which they will appreciate.
How do you track if the buyer got them?
I use ClickMagick tracking which will record the amount of clicks sent to the buyer. Also Udimi tracks them too under stats for the order.
Return filtered clicks sent to my sales page or affiliate link.
In my opinion it will not go back to buyer's link if we leave it blank as it is a filtered click.
it said "Never use a rotator that can eventually redirect the visitor to another solo. If Udimi filter sees that the same visitor jumps in circles through different solos, then this option will be permanently disabled on your account"
Not sure what udimi meant by "another solo" is it another optin page or endless offers/optin pages, some thoughts anyone?
They are saying that you cannot redirect the returned clicks to to fill a different Udimi solo ad order you received.
