What is Smartlink?
One link that routes each visitor to the best-matching offer based on their geo, device or other signals.
A smartlink is a single URL that decides, per visitor, where to send them — picking the highest-value offer for their country, device or source. The affiliate drops one link everywhere and the routing layer optimizes it, instead of hand-picking an offer per placement.
It maximizes earnings across mixed traffic, though it hides which specific offer a visitor saw unless paired with subID reporting.
PayTandem's A/B split-test links are the transparent cousin: weighted routing across destination variants with per-variant conversion reporting, so the winner is measured rather than assumed.
