Link Rotators Explained: How to A/B Test Landing Pages Without Code

A/B testing is essential for optimization, but most testing tools require installing scripts on your website. Link rotators offer a simpler approach: split your traffic between different URLs at the link level, no code required.

In this guide, you'll learn how link rotators work and how to use them for effective A/B testing.

A link rotator is a single URL that distributes clicks across multiple destination URLs based on rules you define. Each click gets sent to one of your destinations, allowing you to test different pages, offers, or experiences.

Example: You create a link rotator with two landing pages. Half your visitors see Page A, half see Page B. After enough clicks, you compare conversion rates and pick the winner.

When someone clicks your link rotator:

1. 1Linkly receives the click
2. 2Based on your rotation rules, it selects a destination
3. 3The visitor is redirected to that destination
4. 4The click is logged with full analytics

You see exactly how many clicks each destination received, and you can check your own analytics to compare conversion rates.

1. 1Log into your Linkly dashboard
2. 2Click Create Link
3. 3In the Link Rotator section, click Enable Rotation
4. 4Add your destination URLs
5. 5Set the weight for each URL (e.g., 50/50 or 70/30)
6. 6Save your link

Split traffic equally across all destinations. Use this when you want a fair test with no bias.

Example: Two landing pages, each getting 50% of traffic.

Send more traffic to certain destinations. Use this when:

• You want to test a variation without risking too much traffic on an unproven page
• One destination is your "control" and should get more traffic
• You're gradually rolling out a new page

Example: 80% to the current page, 20% to the new test page.

Alternate between destinations in order. Each click goes to the next URL in the rotation.

Example: Click 1 → Page A, Click 2 → Page B, Click 3 → Page A, etc.

Test different landing page variations:

• Different headlines
• Different hero images
• Different CTAs
• Long-form vs. short-form content

Set up a 50/50 rotation, send traffic, and compare conversion rates.

Test different offers or pricing:

• 10% discount vs. free shipping
• Monthly vs. annual pricing emphasis
• Bundle A vs. Bundle B

Create multiple versions of the same page with different copy:

• Benefit-focused vs. feature-focused
• Emotional vs. logical appeal
• Short vs. detailed descriptions

Affiliates can test which offers convert best:

• Different products in the same category
• Same product, different merchants
• Different landing page styles

If you have multiple servers or CDNs, use link rotators to distribute load evenly across them.

Test whether automatic language detection or a language selector performs better:

• 50% → Auto-detected language version
• 50% → Language selector page

If Page A and Page B have different headlines, images, AND layouts, you won't know which change caused any difference in results. Change one element per test.

Statistical significance matters. A test with 50 clicks per variation isn't reliable. Aim for:

Use an A/B test calculator to determine the exact sample size needed for your situation.

Behavior varies by day of week and time of day. Run tests for at least one full week (ideally two) to capture these variations.

Linkly tracks clicks to each destination, but you need your own analytics to track what happens after:

• Set up goal tracking in Google Analytics
• Use separate UTM parameters for each variation
• Track sales or signups in your CRM

Pro tip: Add different UTM values to each destination in your rotator:

• Page A: ?utm_content=variation_a
• Page B: ?utm_content=variation_b

Keep a log of:

• What you tested
• Start and end dates
• Traffic volume to each variation
• Results (conversion rates, revenue, etc.)
• Winner and next steps

After your test runs:

1. 1Check Linkly analytics for clicks to each destination
2. 2Check your website analytics for conversion rates
3. 3Calculate statistical significance (use an online calculator)
4. 4Declare a winner if the results are significant
5. 5Implement the winner and plan your next test

When to use link rotators:

• Quick tests without developer involvement
• Testing across different domains
• Testing affiliate offers
• Teams without technical resources

When to use traditional A/B tools:

• On-page element testing (buttons, forms)
• Complex multi-variate tests
• When you need built-in statistical analysis

Test different pages for different countries:

• US visitors: 50/50 rotation between Page A and Page B
• UK visitors: Only see Page C

Set up geo-rules first, then add rotation to specific geo-segments.

Add retargeting pixels to your link rotator. This lets you:

• Build audiences from all variations
• See if ad engagement differs by landing page
• Retarget non-converters with follow-up offers

Run time-limited tests by combining rotation with expiring links:

• Test runs for one week
• After expiration, redirect everyone to the winning page

Goal: Improve signups for a SaaS free trial

Hypothesis: A headline focused on results will outperform one focused on features

Setup:

1. 1

   Create two landing pages:

   • Page A: "Powerful Project Management Software" (feature-focused)
   • Page B: "Get Projects Done 2x Faster" (result-focused)
2. 2

   Create a link rotator in Linkly with 50/50 split

3. 3

   Add UTM parameters to distinguish traffic in Google Analytics

4. 4

   Use this link in all marketing (ads, emails, social)

Analysis (after 2 weeks):

• Page A: 2,500 clicks, 75 signups (3.0% conversion)
• Page B: 2,480 clicks, 112 signups (4.5% conversion)
• Statistical significance: 95%+ confident Page B is better

Result: Page B wins. Update all marketing to use Page B directly, then plan next test (maybe testing the CTA button).

Link rotators make A/B testing accessible to anyone, regardless of technical skills. By splitting traffic at the link level, you can test landing pages, offers, and messaging without touching code. Combined with click tracking and your own conversion analytics, link rotators give you the data needed to continuously improve performance.
