Send one short link to several destinations and let Picolink divide the traffic by weight. The variant a visitor gets is decided without a cookie and holds steady through their session, so the click and the signup that follows land on the same version.
One link points at several URLs with a weight on each. Picolink handles the allocation and keeps each visitor on one side of the test through their session, so the only thing left to do is read your pages and adjust.
Add up to five destinations to a routing rule and give each a weight. Picolink divides incoming traffic across them in those proportions: an even 50/50, a cautious 90/10, whatever the test needs. The weights are relative, so you never have to make them add up to anything.
The variant a visitor lands on is computed from the link plus their request, not rolled fresh on each click, so it holds steady while they stay on the same network and device. No cookie is set and there's no flicker mid-visit. Switch networks between visits and they may cross to the other side; that's the trade for keeping it cookie-free.
Each variant is its own URL, so whatever you already use to track signups or sales attributes them to the right page. When the numbers are in, change the weights or swap a variant outright. The short link and its QR never change, so a printed code or a sent email keeps working through the whole test.
Anywhere you'd want two versions behind a single address, a weighted link does the routing. These are the setups we see most.
Run a new headline against the current one at a 50/50 weight. Same audience, same link, two versions, and the winner takes the traffic when you adjust the split.
Start a new page at a small weight, watch it hold up on your own funnel, then raise the weight step by step. A canary release without a deploy.
Rotate several offers behind one link in an ad or on a printed QR. Reweight toward whatever pulls, without reprinting or re-uploading the creative.
Scope the split to a country or device. Try a new mobile checkout on mobile visitors only; everyone else stays on the page you trust.
Build the rule, set the weights, and share one link. Tilt it toward the winner whenever the numbers come in, no new link required.
