What is A/B testing?

A/B testing is a method of comparing two or more variations of a destination URL to see which performs better. It works by randomly redirecting users who click the same short link to different target URLs, then measuring which version gets better results based on metrics.

Where to find A/B testing?

When the link builder is open, you’ll find the A/B test button in the bottom action row. Click to open the dialogue.

A/B testing builder

With the builder open, you are able to add additional destination URLs, set the traffic percentage, and set the completion date. A minimum of 2 URLs is required to create the test.

Testing URLs

You can enter a maximum of 4 additional testing URLs that you’d like to send your traffic to.

If you need to remove any URLs you’ve added, click the X icon to the right of each input to remove it.

Traffic split

By default, the traffic is split evenly between each of the URLs, but this can be changed depending on your preference.

Click and drag the dividers between each group to adjust the traffic to each destination URL. The minimum percentage you can set traffic to is 10%. ### Completion Date By default, A/B tests will be set to run for 2 weeks, as that is enough time to collect performance data to make a decision

You can run a test for a shorter period, but that’s not recommended because in most cases, you won’t collect enough data to make a decision. The longest you can run a test for is 6 weeks.

Active A/B tests

While an A/B test is active, a flask icon is shown on each link. You can see this while viewing all your links.

You can click this icon to expand the current link view to show all the destination URLs you’ve entered for testing. This will show you the traffic percentage you’ve set and the click, lead, and sale performance.

Completing A/B tests

There are two ways A/B tests can be completed. They can either be manually ended early or the scheduled completion date passes.

1. Completion date has passed

   By default, your A/B test will complete when the scheduled date passes. Here’s how the new destination URL is selected:

   1. Select the link with the highest amount of conversions
   2. If conversions are tied, select the link with the highest conversion rate (conversions ÷ clicks)
   3. If still tied, select the link with the highest clicks

   OR - If no conversions are recorded or tracked

   1. Select the link with the highest number of leads
   2. If leads are tied, select the link with the highest lead rate (leads ÷ clicks)
   3. If still tied, select the link with the highest clicks
2. Ending the test manually

   To end your test before the scheduled date, open your A/B settings and click End A/B test in the bottom left of the modal.

   

   From here, you’ll select the new destination URL for your short link.

   

   After clicking End test, make sure to save your link changes in the next screen to confirm the changes.
