Link Rotation

Link rotation splits incoming traffic from one short link across multiple destination URLs — enabling A/B testing, offer comparison and load distribution from a single shared link.

---

Definition

Link rotation is a URL shortener feature that distributes incoming clicks from one short link across two or more destination URLs according to configured percentages. A visitor who clicks the link is redirected to one of the configured destinations; the next visitor goes to another. The rotation is automatic and invisible to the visitor.

The split does not have to be equal. Common configurations include 50/50 (equal A/B split), 70/30 (weighted towards a presumed winner while still testing), or any custom percentage distribution across multiple destinations.

How Link Rotation Works

1. A short link is configured with two or more destination URLs and a percentage split (e.g. 50% to URL A, 50% to URL B)
2. The short link is distributed — in an email, SMS, social post, QR Code — as a single shared URL
3. Each incoming visitor is assigned to a destination based on the configured split, typically using round-robin or random assignment
4. The visitor is redirected to their assigned destination without any indication that rotation is occurring
5. Click analytics track performance for each destination separately, enabling comparison

Link Rotation vs A/B Testing

Link rotation is the mechanism; A/B testing is the methodology that uses it. The distinction matters for understanding what link rotation can and cannot measure:

• What link rotation measures directly: which destination receives more clicks from the shared short link. Click analytics show per-destination click volume, device breakdown, timing and referrer.
• What requires additional measurement: downstream conversion behaviour after the click — sign-ups, purchases, form completions. These require the destination page's own analytics (GA4, conversion tracking) to be set up and compared per variant.
• The advantage over platform-level A/B testing: link rotation operates independently of the landing page platform. You can A/B test two pages on completely different platforms, or test two offers where you have no ability to modify the destination pages themselves.

A/B and A/B/C Testing in Cuttly

Cuttly supports both A/B testing (two destination variants) and A/B/C testing (three destination variants). The available variant count depends on your subscription plan — check your plan's features at cutt.ly/pro-pricing.

The traffic split between variants is set using a slider — you can configure any proportion, not just equal splits. For example: 70% to A and 30% to B, or 60% to A, 25% to B and 15% to C.

Click counting for alternative destinations (B and C) follows the same counting method — total or unique — as configured for the main link. Counting is consistent across all variants.

How to Set Up A/B/C Testing in Cuttly

1. Go to the list of short links in your dashboard
2. Click the ABC test settings icon for the short link you want to test
3. Depending on your subscription plan, you will see the A/B form or the A/B/C form
4. Enter the alternative destination URL(s) — B for A/B, or B and C for A/B/C
5. Set the traffic split proportions using the slider
6. Save — the rotation becomes active immediately

Use Cases

• Landing page testing. Two versions of a campaign landing page — different headline, different layout, different offer emphasis — tested from a single email or SMS link. Analytics show which version receives more engaged traffic before downstream conversion data is available.
• Offer variant testing. Two different promotional offers tested on the same audience segment, with the winning offer receiving all traffic after a testing period.
• Creative testing. Two different destination formats — long-form article vs short video — tested with the same link across the same distribution channels.
• Platform migration testing. Splitting traffic between an existing page and a newly built version to validate the new version's performance before full migration.
• Load distribution. Distributing traffic across multiple server instances or regional endpoints from a single public-facing link — useful for high-traffic events where single-server load is a concern.

Best Practices

• Run rotation tests long enough to achieve statistical significance before declaring a winner — short tests with small sample sizes produce unreliable results.
• Test one variable at a time. Testing a different headline AND a different layout simultaneously makes it impossible to attribute performance differences to either change specifically.
• Use UTM parameters on each destination URL to carry split assignment into downstream analytics — this allows conversion comparison per variant in GA4 or your analytics platform of choice.
• Once a winning variant is determined, update the link to route 100% of traffic to the winner rather than continuing the split indefinitely.
