Smart link (router)
Auto-routing affiliate URL — see also 'smartlink'.
A 'smart link' (one word or two — used interchangeably) is the same concept as 'smartlink' — a single affiliate URL that auto-routes traffic to the best-converting matching offer based on geo/device/time. The two-word form is more common in the dating and adult sub-verticals; one-word form in sweepstakes and crypto.
Example
MyLead smart-link routes Indonesian Android Chrome traffic to a sweeps-iPhone offer at $1.20 payout, while routing US iOS Safari to a $3.40 dating-DOI offer — affiliate sets one URL, network handles per-visitor logic.
