Smart A/B Testing: Let Data Pick Your Winners
Most marketers test links with their gut. trimy's Smart A/B Testing does the math for you — automatically splitting traffic between variants and declaring a confident winner based on real performance data, so you can stop guessing and start optimizing.

Illustrative example — not live data
Variant B is converting 55% better with high statistical confidence — trimy's Auto-Optimize would already be sending it the majority of new traffic.
What Is Smart A/B Testing?
Smart A/B Testing lets you create two variants of a short link pointing to different landing pages or destinations. When someone clicks your short link, trimy's algorithm intelligently routes them to Variant A or Variant B, tracks which variant generates more conversions, and automatically identifies a statistical winner.
Unlike basic 50/50 traffic splits, trimy uses smart adaptive traffic routing — meaning it learns which variant is winning and gradually shifts more traffic toward the better performer while still testing the weaker one. You get faster results and waste less traffic on the losing option.
How Smart A/B Testing Works
-
1
Create an A/B test
In trimy's dashboard, go to your short link and click "Create A/B Test". Specify two destination URLs (Variant A and Variant B) and optionally choose a traffic split ratio.
-
2
Start the test
Once activated, every click to your short link is routed to one of the two variants. trimy logs which variant was shown, allowing you to track conversion rate per variant.
-
3
Monitor in real time
Your A/B test dashboard shows live clicks and conversion rates per variant (if you've set up conversion tracking). As the test runs, trimy identifies the leading variant so you can make an informed decision — or let Smart Auto-Optimize do it for you automatically (Professional+).
-
4
Get a winner or stop manually
Once trimy has enough data to confidently declare a winner, it flags the result. Alternatively, stop the test at any time and manually declare a winner. You can then promote the winning destination as the default.
Real-World Use Cases
Email Campaign Optimization
A marketing agency sends an email with a trimy short link (A/B test). Variant A points to a blue CTA button, Variant B to a red one. After 5,000 clicks, the red button wins with 8.5% conversion vs. 6.2%. The agency now knows exactly which design to use in future emails.
Landing Page Headlines
An SaaS company tests two headline variations on their product page. Variant A: "Automate Your Workflow". Variant B: "Save 10 Hours Every Week". trimy's test reveals that Variant B drives 23% more signups. No need for GA4 funnel setup — trimy gives you the answer in a day.
App Download vs. Web Sign-up
A mobile app company wants to know: should we drive users to the App Store or to our web signup? Using trimy's A/B test, they discover that App Store links drive 35% higher engagement. Now they can confidently shift all marketing to the winning funnel.
Pricing Page Variants
An online course platform tests two pricing pages with a trimy A/B test: $49/month vs. $39/month with a 30-day free trial. The test shows that the lower price point with trial generates 18% more enrollments and higher lifetime value. Decision made, no guessing.
What Makes trimy's A/B Testing Smart

Confident Winner Detection
trimy measures each variant's performance and highlights the leading variant based on real data — not just an early lucky streak. With conversion tracking set up, you see exactly which variant drives more results.
Real-Time Results
See conversion rates and winning likelihood update in real time. No waiting 7 days for GA4 reports — get insights in hours.
Flexible Configuration
Set initial traffic splits (e.g., 70/30 to favor one variant), enable auto-stop on significance, or manually pause/resume tests at any time.

Frequently Asked Questions
How many clicks do I need for a valid A/B test?
It depends on your conversion rate and how different the variants perform. trimy shows a recommended sample size when you set up the test. Most campaigns gather enough data in 500–5,000 clicks (hours to days).
Can I test more than 2 variants?
Yes. trimy supports multiple variants per test — not just two. Traffic allocation optimizes across all variants simultaneously, so adding a third or fourth destination is fully supported.
What happens if I stop a test early?
You can stop an A/B test at any time. trimy will show you the current leading variant and let you manually select which variant becomes the default. You won't lose any historical data.
How do I track conversions for my A/B test?
Add trimy's JavaScript snippet to your confirmation or thank-you page and fire a conversion event there. trimy then records each conversion against the variant that sent the visitor, and shows conversion rates per variant in your dashboard. Without the snippet, you can still see clicks per variant and pick a winner manually.
Can I run multiple A/B tests on the same short link?
No. Only one A/B test can be active per short link. However, you can create a new short link, set up a fresh A/B test with new variants, and run it independently.
Is A/B testing available on custom domains?
Yes. A/B testing works on all short links, whether they use trimy.io or your custom domain. The testing and conversion tracking logic is the same.
Stop guessing. Start optimizing.
Every marketing decision deserves data. trimy's Smart A/B Testing makes it easy.
