A/B Split Testing for Short Links in WordPress

Guessing which landing page converts better costs you sign-ups. URL Shortify PRO's A/B split testing removes the guesswork: one short link sends different visitors to different destination pages automatically, tracks a conversion goal, and shows you which variant wins. A/B testing is built on Link Rotation — a Dynamic Redirection type on the link form — and is available in URL Shortify PRO.

What is A/B testing?

A/B testing (also called split testing) sends different visitors to different destination pages through a single short link, then measures which page performs better so you can keep the winner. In URL Shortify it works by adding several weighted URLs to one link and enabling Split Test with a Goal Link, so each variant's conversion rate is tracked automatically.

Example: You have two versions of a landing page and want to know which converts more visitors into sign-ups. Instead of guessing, you create one short link, add both URLs, and let URL Shortify split the traffic. After a few days the results tell you which page won.

How it works

When someone clicks your short link:

1. URL Shortify picks a destination URL from your rotation list, based on the traffic weights you set.
2. The visitor is redirected to that URL seamlessly.
3. URL Shortify records which variant they saw.
4. If a Goal Link is set and the same visitor later clicks it, that visit is counted as a conversion for the variant they saw.

Over time, the link's stats page builds a clear picture of how each variant is performing.

Requirements

• A URL Shortify PRO plan.
• At least two destination URLs configured on a link via Link Rotation.

Setting up an A/B test

Step 1 — Create or edit a link

Go to URL Shortify → Links and either add a new link or click Edit on an existing one. Enter your primary destination URL in the main Target URL field as normal.

Step 2 — Enable Link Rotation

In the Dynamic Redirection section, select Link Rotation from the dropdown. A table appears with Target URL and Weight columns:

Target URL	Weight
Above Entered Target URL (your primary URL — locked)	50%
(Add a row for each variant)	50%

The first row is locked to your primary URL and shows Above Entered Target URL — change it in the main Target URL field at the top of the form. Use the + (add) button in the Action column to add each additional variant URL; remove a row with the trash icon.

Step 3 — Set traffic weights

Each URL has a Weight dropdown (0%–100%) controlling its share of visitors.

• Weights should total 100% or less — if they exceed 100%, URL Shortify shows a warning asking you to reduce the total.
• Equal weights split traffic evenly; a clean 50/50 test uses the same weight on both URLs.
• Unequal weights (for example 80/20) send most traffic to a proven page while cautiously testing a new one.

Variant	Weight	Traffic share
Page A	50%	50%
Page B	50%	50%

Step 4 — Enable Split Test mode

Toggle on the Split Test switch. This tells URL Shortify to track the rotation as an experiment with conversion goals rather than a plain traffic splitter. With Split Test on:

• Results on the stats page show a Split Test badge.
• The winning variant is determined by conversion rate, not just click volume.
• The Goal Conv. % column appears in the results table.

Step 5 — Select a Goal Link

The Goal Link is another short link in your account that represents a successful conversion — for example a "Thank You" page after a form submission, a checkout confirmation, or a product page.

To set it, make sure the conversion page already has its own short link in URL Shortify, then choose that link from the Goal Link dropdown. When a visitor clicks your test link and later clicks the Goal Link, URL Shortify counts a conversion for whichever variant they saw.

Step 6 — Save

Click Save Link. Your short link is now live and splitting traffic between your variants.

Reading your results

Open the link's stats page (click Stats next to the link in the Links list) and scroll to the Link Rotation Results section.

The results table

Column	What it means
#	The variant letter — A is your primary URL, B your second, C your third, and so on.
Destination URL	The full URL this variant sends visitors to.
Traffic %	The configured weight share for this variant.
Total Clicks	Every click that landed on this variant, including repeat visits.
Unique Visitors	Distinct individuals who visited this variant (based on a 1-year browser cookie).
First Clicks	Clicks from people visiting the short link for the very first time.
Goal Conv. %	(Split Test mode only) Percentage of unique visitors who later clicked your Goal Link — your conversion rate.

The best-performing variant is marked with a ▲ Leading label:

• In Split Test mode, the leader has the highest conversion rate.
• In rotation-only mode, the leader has the most total clicks.

The summary bar

Below the table, two summary cards appear:

• Winning Variant — names the leading variant with its conversion rate and total conversions.
• Totals — total clicks and conversions across all variants, plus the overall conversion rate (total conversions ÷ total unique visitors).

Understanding conversion rate

Conversion rate = Conversions ÷ Unique Visitors × 100. A conversion is counted when a unique visitor clicks your short link, sees a variant, and that same visitor later clicks your Goal Link. The conversion is attributed to whichever variant the visitor saw.

Variant	Unique Visitors	Conversions	Conversion Rate
A — Original landing page	289	87	30.1% (winner)
B — Redesigned landing page	184	37	20.1%
C — Minimal landing page	76	11	14.5%

Here, Variant A wins with a 30.1% conversion rate despite Variant B's slightly higher traffic share.

Tips for better results

• Run the test long enough. Aim for at least 100 unique visitors per variant before drawing conclusions.
• Test one thing at a time. Change only a single element between variants so you know what drove the difference.
• Choose a meaningful Goal Link. Use a page visitors reach only after completing the action you care about, such as a post-submission "Thank You" page.
• Use equal weights for a fair test. A clean 50/50 split needs matching weights; unequal weights suit cautious rollouts.
• Give it time. Results accumulate over days — checking hourly is misleading.

Conclusion

A/B split testing lets one short link route visitors to competing pages, track conversions against a Goal Link, and surface the winner by conversion rate — no separate tools required. It is built on Link Rotation, so start there to set your variants and weights, then enable Split Test. To route visitors by country or device instead of splitting them, see Geo Location and Technology redirection.

FAQs

Can I run a rotation with more than two URLs?

Yes. Add as many destination URLs as you like using the + button in the Action column. Each gets its own variant letter (A, B, C, D…) and its own row in the results table with separate click, visitor, and conversion figures. Keep the combined weights at 100% or less so URL Shortify distributes traffic without a warning.

What happens to clicks recorded before I turned on Split Test mode?

Clicks recorded before you enabled the Split Test toggle still count in Total Clicks and Unique Visitors. However, conversions are only tracked from the point the Goal Link is configured, so early clicks may show lower conversion numbers for those variants until fresh traffic accumulates.

Does the Goal Link have to be a link I created in URL Shortify?

Yes. The Goal Link must be an existing short link in your URL Shortify account, because URL Shortify detects a conversion by seeing the same visitor click that short link. Create a short link for your conversion page first, then select it from the Goal Link dropdown on the test link.

Will the same visitor always see the same variant?

No. Variant assignment happens on each click based on the configured weights, so the same person visiting twice may land on different variants. For most tests this is fine, and the unique-visitor count helps you interpret results despite the per-click randomness.

How do I stop or pause an A/B test?

Edit the link and change the Dynamic Redirection setting away from Link Rotation (or point all weight to a single URL). Traffic stops splitting immediately, and the historical results remain visible on the link's stats page so you keep the data you collected.

Is there a minimum number of clicks for reliable results?

There is no enforced minimum, but fewer than 50–100 unique visitors per variant tends to produce results you cannot trust. The more traffic you collect, the more confident you can be in the winning variant — so let the test run across several days rather than deciding after a handful of clicks.
