What is A/B Testing for Short Links?
A/B testing (also called split testing) for short URLs means using one link that can lead to multiple destinations. Instead of guessing which landing page, offer, or experience performs best, you let real user behavior decide.
With S.EE, you define rules that determine where each visitor goes. Over time, you compare which version gets more clicks, conversions, or engagement — then double down on what works.
S.EE supports four main routing types:
- Geo-based routing — by country, region, or city
- Device-based routing — desktop, mobile, or tablet
- Language-based routing — browser language preference
- Random percentage split — classic A/B/n testing
When Should You Use A/B Testing?
Smart routing and split testing help you deliver the right experience to the right audience. Here are common scenarios where A/B testing shines.
Landing Page Experiments
Test different headlines, images, or calls-to-action by sending users to variant pages. Learn which version gets more sign-ups or purchases.
Geo-Based Routing
Send EU visitors to a GDPR-compliant page and US visitors to a different version. Target specific regions with localized promotions.
Device-Based Routing
Show a streamlined mobile checkout to phone users while desktop users see the full-featured experience. Optimize for each device type.
Language-Based Routing
Detect browser language and redirect users to content in their preferred language automatically — no manual selection needed.
Percentage-Based Splits
Run classic A/B tests with 50/50 splits, or gradually roll out a new page to 10% of traffic before going live to everyone.
Multi-Variant Testing
Test more than two versions at once. Split traffic across multiple destinations and find the best performer faster.

How A/B Testing Works in S.EE
Setting up an experiment takes just a few minutes. Follow these steps to start testing and optimizing your links.
Create or Select a Short Link
Start by creating a new short link in your S.EE dashboard, or choose an existing link you want to turn into an experiment.
Add Multiple Destinations
Enter the different URLs you want to test. Each destination can be a unique landing page, offer, or experience.
Define Your Routing Rules
Set up rules based on country, region, city, device type, browser language, or random percentage splits. Combine multiple rules for advanced targeting.
Activate & Monitor Results
Turn on your experiment and share the short link. Watch real-time analytics to see which variant performs best, then pick your winner.
Target by Location, Device & Language
S.EE's smart routing runs on the edge, instantly directing visitors to the right destination based on your rules. No delays, no complexity — just seamless personalization.

Frequently Asked Questions
Everything you need to know about S.EE A/B Testing and smart routing.
How many destination URLs can I add to one short link?
You can add multiple destination URLs to a single short link. The exact limit depends on your plan, but most users can set up as many variants as they need for comprehensive A/B or multi-variant testing.
Can I combine geo, device, and language rules?
Yes, S.EE allows you to layer multiple routing rules. For example, you could send mobile users from France to one URL and desktop users from Germany to another — all from the same short link.
How are random percentage splits calculated?
When you set up a percentage-based split, S.EE randomly assigns each visitor to one of your destinations based on the percentages you define. A 50/50 split means roughly half of your visitors go to each variant.
Will A/B testing affect my existing link analytics?
No, your analytics remain fully intact. In fact, you get enhanced insights showing how each variant performs, including clicks, conversions, and geographic breakdowns for every destination.
Do I need a paid plan to use A/B testing?
Basic A/B testing features are available on all plans. Advanced routing options like geo-targeting by city or combining multiple rule types may require a premium plan. Check our pricing page for details.
How quickly do routing rules take effect?
Routing rules are applied instantly. As soon as you save your experiment, new visitors will be routed according to your rules with no delay or propagation time.
