What is Fibr Script?

The Fibr Script is a lightweight, auto-generated code snippet that powers Fibr’s personalization features on your website. Once installed, it allows Fibr to identify users visiting your site in real time and check whether they meet any of the conditions you’ve set, such as those for ad or audience personalization, A/B testing, and more.

If a user matches one of your rules, Fibr instantly applies the appropriate personalized variant, ensuring a seamless experience as the page loads in their browser. This enables you to deliver tailored content without affecting your site’s performance.
