Why Run an A/B Test

Test your hypotheses on real traffic and keep whatever actually works

Data-backed decisions

Stop guessing which URL performs better — compare clicks by variant and pick the winner based on facts.

Flexible traffic split

Give each variant its own percentage of traffic — from a cautious 10% test to an even split.

A fair test

Sticky assignment means each visitor always sees the same variant, so your results stay clean.

Winner in one click

Once a leader emerges, declare it the winner and the link permanently switches to the best-performing URL.

What You Can Test

Three common scenarios where an A/B link test helps you find the best variant

A VS B 🏆
Landing pages

Compare two landing pages and keep the one that drives more clicks and sign-ups.

A Buy VS B Sale −20% 🏆
Buttons and offers

Find out which call-to-action or offer resonates more with your audience.

A VS B 🏆
Ad creatives

Send traffic to different creatives or product pages and pick the winner by clicks.

How It Works

The link automatically splits traffic by weight and keeps each visitor locked to their variant

Control + up to 3 variants

The link's main URL is the control; add up to three competing variants alongside it.

Percentage traffic weights

Give each variant its own share of traffic. Whatever's left over automatically goes to the control.

Sticky assignment

Each visitor always lands on the same variant, with no extra data stored.

Clicks are the metric

Comparison is based on click count and traffic share for each variant.

Per-variant stats

A dedicated report shows clicks, unique visitors, and traffic share for every URL.

Start and stop anytime

Start, pause, and restart the test whenever you like — variants and weights are preserved.

Declare a winner

Pick the best-performing variant as the winner, and the link permanently switches to its URL.

Works with QR codes and analytics

How to Run an A/B Test

Five steps — from a control URL to declaring a winner

1
Create a link

Sign up on Lix.li and create a short link. Its main URL becomes the control variant that everything else is compared against.

2
Add your variants

In the link form, add up to 3 competing variants and set a traffic weight for each. Whatever percentage remains goes to the control.

3
Launch the test

Click "Start Test" — traffic will start splitting across the variants according to the weights you set.

4
Watch the stats

Your link stats show clicks and traffic share for every variant — compare results in real time.

5
Declare the winner

Once a leader is clear, declare it the winner in one click: the test ends, and the link permanently points to the URL you chose.

A/B Testing FAQ

It's a single short link that points to several different URLs. Traffic is split between them, and you compare clicks to find out which variant performs best.
The control (the link's main URL) plus up to 3 competing variants — up to 4 destinations running at once.
By the percentage weights you set for each variant. Whatever percentage is left over goes to the control URL.
No. Assignment is sticky: a visitor always lands on the same variant on repeat visits, so the test stays fair.
Clicks for each variant and their share of total traffic — a clear signal of which URL is pulling more visitors.
In one click: you declare a variant the winner right from the stats page. The test ends, and the link permanently points to that URL from then on.
Yes. You can stop a test and start it again later — your variants and their weights are saved.

Test Your Hypotheses and Grow Conversions

Launch an A/B test in a couple of minutes — and let the numbers decide, not guesswork.

A/B testing for links (split testing) on Lix.li lets you compare several destinations for a single short link on real traffic. You shorten a link, add variants with traffic weights, and traffic is automatically split across the different URLs. Instead of guessing which landing page, button, or offer will perform better, you get the answer straight from the clicks.

The test is built to be fair: assignment is sticky, so the same person always sees the same URL on repeat visits, and your results stay clean. The control (the link's main destination) is compared against the variants by clicks and traffic share — a dedicated stats report shows which variant is pulling more clicks and how many unique visitors it has picked up. Once a leader is obvious, declare it the winner in one click, and the link permanently switches to the best-performing URL.

Link split testing is a natural fit for landing pages, ad creatives, buttons, and offers: one short link in an ad or your bio splits your audience into groups and shows you what actually works. You can start, pause, and restart an A/B test any time, and the link itself stays a regular Lix.li short link: turn it into a QR code and track it in your stats. A/B testing is available on the Premium plan.
