A smartlink is a single affiliate link that automatically sends each visitor to the offer most likely to convert for them. Instead of choosing one offer per country and device, you send all your traffic to one URL; the network's algorithm reads each click — country, device, OS, browser, carrier, connection type, time — and redirects the user to the best-performing matching offer from its pool.
How the rotation works
- Click arrives with its parameters and your sub-IDs.
- Filtering: the network removes offers that do not accept this country, device, traffic type or vertical.
- Scoring: remaining offers are scored on recent performance — usually EPC (earnings per click) for similar traffic — sometimes with an exploration share sent to new offers to keep learning.
- Redirect: the user lands on the chosen offer.
- Conversion and postback: the network records the conversion and fires a postback to your tracker with your sub-IDs and the payout.
Most smartlinks are organised by vertical — dating, sweepstakes, finance, gaming, adult — so you choose the smartlink that matches your traffic and audience.
When smartlinks make sense
- Testing a new traffic source: a smartlink tells you quickly whether the traffic converts at all.
- Mixed or long-tail geos: you do not need offers for 80 countries — the smartlink has them.
- Popunder and push traffic where users land directly on offers.
- Monetising leftovers: traffic your main offers do not accept.
- Publishers who want one link to monetise a site, app or social audience.
When direct offers are better
- You know exactly which offer converts best in your main geo.
- You want a higher payout negotiated directly with the advertiser.
- You need the offer's specific landing page or a custom funnel.
- The vertical requires compliance control the smartlink does not give you.
Many media buyers do both: test with a smartlink, then move the best-performing segments to direct offers.
How to judge a smartlink network
| What to check | Why it matters |
|---|---|
| EPC by geo and traffic type | The real measure of how well the rotation monetises your clicks |
| Verticals and offer count | More relevant offers means better matching |
| Postback support and sub-IDs | You must see conversions per placement in your own tracker |
| Payment terms | Minimum payout, frequency (weekly is common) and methods |
| Traffic rules | Which traffic types and sources are allowed |
| Transparency | Whether you can see which offers converted |
| Support | A manager who shares data and fixes issues quickly |
Compare networks on the same traffic in the same period. EPC claims on review sites are not comparable to your own traffic.
Optimising smartlink traffic
- Pass zone/placement IDs from the traffic source into the smartlink's sub-ID fields.
- Block placements that spend without converting; build allowlists of the winners.
- Separate campaigns by geo and device so the algorithm and your bids learn on consistent traffic.
- Try a short pre-lander to filter low-intent users before the redirect.
- Ask your manager whether you can exclude specific offers that convert badly for your traffic.

FAQ
What is the difference between a smartlink and a direct link?
A direct link sends all traffic to one offer. A smartlink chooses an offer for each click based on the visitor's parameters and recent performance.
Are smartlinks good for beginners?
Yes, as a learning tool. They let you test traffic sources without picking offers for every country. Over time, experienced buyers move their best segments to direct offers.
How do smartlink networks make money?
They earn the difference between what advertisers pay for a conversion and what they pay you, like any network. The algorithm aims to maximise revenue per click for both.
Can publishers use smartlinks without ad networks?
Yes. Publishers place smartlinks on websites, social profiles, messaging channels or in apps and are paid per conversion or, on some platforms, per impression.
