This guide provides a step-by-step process to create an A/B testing campaign on Fibr. Ensure your website is validated on Fibr before starting. Detailed instructions on website validation and Fibr script addition are available as separate docs.

This tutorial outlines the steps for creating individual experiments. To implement multiple experiments at scale, please visit this page, where you can utilize the Bulk Creation feature for A/B Testing.

• Ensure you’ve already added and validated the Fibr script on the URL you plan to test.

• From your Fibr dashboard, go to Experimentation in the left-hand panel.

• Click A/B Testing and then New Campaign at the top right.

• Enter your website URL, name your campaign (e.g., “AI A/B Test Guide”), and click Create.

2. Set Up Your Variants

• After campaign creation, you’ll land on the Campaign Page, where the default variant (your current page) is set to 100% traffic.
