How Smartlinks Work

A smartlink is a single tracking link that automatically routes each visitor to whichever offer, out of a pool of pre-approved campaigns, is likely to convert best for them. Instead of manually choosing one offer and hoping it fits every visitor, you hand that decision to an optimization engine that factors in geography, device type, time of day, and historical conversion data.

For publishers managing a lot of untargeted or broad traffic, smartlinks solve a real problem: you cannot manually optimize offer selection for every visitor segment, but an automated system can attempt to in real time. This builds directly on the concepts in our affiliate tracking explained guide, since smartlinks still rely on the same underlying click and postback infrastructure.

In practice, most experienced affiliates use a hybrid approach: a hand-picked offer for their core, well-understood audience, and a smartlink as a fallback for the long tail of traffic that does not fit neatly into one campaign. This is especially common in mobile affiliate marketing, where traffic quality signals shift quickly and manual optimization is harder to keep up with. To see how this affects your bottom line, revisit our guide on how to increase EPC, since smartlink performance is usually measured the same way as any other offer.
