A/B testing and geo routing from a single link

A link doesn't have to send everyone to the same place. Once you accept that, a single short URL becomes a surprisingly powerful routing tool: it can run an experiment, or it can adapt the destination to who's clicking. TRIMS supports both, and neither requires a line of code or a developer's afternoon.

A/B testing: let the data decide

When you're unsure which landing page converts better, guessing is expensive and arguing is worse. A/B testing on a link splits incoming traffic across two or more destinations by whatever percentages you choose, then measures how each one performs. Instead of a meeting about which page is stronger, you get an answer from real visitors.

The setup is deliberately simple: point one link at several variants, set the split, and share that single URL everywhere. Behind it, TRIMS distributes clicks and tracks the outcomes so you can promote the winner with confidence rather than opinion.

Geo routing: the right place by location

A global audience rarely wants a single global page. Geo routing sends visitors to different destinations based on their country, so the same link lands a shopper on the store that ships to them, a reader on the page in their language, or a customer on the site with the right currency and pricing.

  • Split traffic across variants by custom percentages
  • Route by country to localise language, currency, or store
  • Route by device to send mobile and desktop where they fit
  • One shared link, many smart destinations behind it
  • Full analytics on how each route and variant performs

Device routing, for good measure

The same routing engine can branch on device. Send mobile visitors straight to the app store listing while desktop visitors get the full web experience, all from one link you share once. The visitor never sees the machinery — they just arrive somewhere that fits how they're browsing.

A link that adapts to the person clicking it does more work than a hundred links that don't.

A/B testing and routing rules are available on paid plans, and they compose with the rest of your analytics: every variant and every route reports its own numbers, so you can see not just that a link works, but which path through it works best.
