Enable custom attributes in Optimize

Add custom attributes in Optimize to filter results and/or target visitors with optimizations.

Attributes are characteristics associated with your visitors (e.g., demographics). You can use a Webflow API to set custom attributes for visitors that leverage data you’ve learned, collected, or acquired. In Optimize, you can then add custom attributes to leverage as optimization results filters or as optimization audiences to target visitors.

How to set custom attributes for each visitor

To set a custom attribute, you can use the wf.setAttributes() Browser API. Review the API documentation to learn more.
