Migrate from uploaded audiences to list attributes

List attributes target visitors based on their membership in an audience you already defined somewhere outside of Optimizely Web Experimentation. With this feature, you import a custom list of users and then create audience conditions based on those lists.

The benefits of list attributes include the following:

• Data upload methods – In-browser, REST API, Amazon S3
• List size limit – Unlimited (when uploading via Amazon S3)
• Ingest speed (time between data upload and availability of data for targeting) – Up to one hour, and typically much faster
• Management interface – Optimizely Web Experimentation

Audience builder

Go to Audiences > Saved and select an audience or create a new one. The audience builder is where you go to create Optimizely Web Experimentation audiences. Go to  External Attributes > List Attributes and drag the attribute you want into the Audience Builder.

You can also search for a specific list using the Browse by Name search box.

Management interface

Go to Audiences > Attributes to view the management interface where you create, modify, and archive lists in Optimizely Web Experimentation.
