Customer Personas allow you to test your personalized web pages by viewing them with different property sets in the preview. Without Customer Personas, an editor can only see the effects of personalization for the current set of properties, which articles have been clicked by the editor within the preview CAE, for instance. In order to verify the desired effects of personalized content, an editor needs to be able to mimic a specific Customer Persona with the desired interests. This is achieved by first creating the necessary Customer Persona within the CoreMedia CMS repository and switching from one Customer Persona to another in the CoreMedia Studio preview view.
