Most people pick a destination for a link and hope it works. A/B testing replaces the hope with evidence: you send the clicks on one short link to two or more destinations, watch which converts, and keep the winner — without ever changing the link you already shared.
Why test the destination, not the link
The link you put in a video description, a bio, an email, or a printed QR code is expensive to change. If you decide next week that a different landing page converts better, you do not want to re-record the video or reprint the flyer.
A Smart Link solves this by separating the link from the destination. The short URL stays fixed; the destinations behind it are yours to change, add, remove and re-weight at any time. A/B testing is just that flexibility turned into an experiment.
Setting up a split test
- Create a Smart Link as usual.
- Add two or more destinations — for example your in-depth review post and the direct product page.
- Choose how to split the traffic: evenly, or by weight.
An even split sends 50/50. A weighted split lets you protect a proven offer while you test a challenger — say 70% to the page you trust and 30% to the new idea. Change the weights whenever you like; the new ratio applies to clicks from that moment on.
Reading the result
Because every click flows into the same analytics, you get a breakdown by destination, country, device and time — with bots and link-preview crawlers filtered out, so you are comparing real human traffic, not noise. When one variant clearly wins, point the whole link at it. Every share you have already published keeps working and now sends everyone to the best performer.
A/B testing vs rotation
They use the same engine. A/B testing is when you compare variants to find a winner. Rotation is when you deliberately keep spreading traffic — cycling several affiliate links or mirrors so no single one is overloaded, or alternating offers on purpose. Both are set up the same way: add destinations and weights to one link.
Stack it with geo and device routing
The best part is that testing sits on top of the routing you already use. A single link can first send US visitors and UK visitors to their local stores, then A/B test two landing pages within the US traffic. Country, device, blocking, scheduling and QR all keep working underneath the test.
Where to start
Pick one link that matters — your highest-traffic bio link or a key video description — and add a single challenger destination at a 20–30% weight. Give it a week, read the numbers, and promote the winner. You will never go back to guessing.

Frequently Asked Questions
Do I need to change my link to run a new test?
No. The short URL stays the same while you add, remove or re-weight the destinations behind it — so you can test without touching a video description, bio, or printed QR code.
Can I combine A/B testing with country routing?
Yes. A/B testing sits on top of the same Smart Link, so a link can route by country and device first, then split the remaining traffic across variants.
How do I know which variant won?
Your analytics break clicks down by destination, country, device and time with bots filtered out, so you can see which variant pulls real human traffic before promoting it.
