From the Personalize > People > Person Detail > Profile Details page, the panel on the left displays profile summary information for the visitor.
The profile summary includes the following information:
Persona: You can assign one or more personas to each item of content on your website. The field displays the persona the visitor viewed most frequently. For example, if the visitor viewed one piece of content tagged with the persona Foodie and three pieces of content tagged with the persona of Hiker, the field will display the Hiker persona.
If Personalization doesn’t yet have enough information about the visitor to assign them a persona, the Persona field won’t display.
Sometimes Personalization displays error messages in the Person Details section when you view a particular visitor’s details. The messages are due to a merge failure, which is a processing problem that can occur during a visitor capture. Merge failures happen when one website visitor has more than 25 identifiers. Visitors often have several identifiers. If a visitor logs into your website from a different browser or signs in with a different email address, the action will generate a new identifier. If a visitor has more than 25, instead of the 26th identifier getting merged to the same website visitor, the Personalization service will generate a new tracking ID and merge the 26th identifier to the tracking ID. This helps prevent the Personalization service from experiencing performance issues related to too-large visitor profiles.
The errors don’t affect how Personalization works, other than improving its performance. You don’t need to take any action related to the messages, other than investigating why Personalization may be creating overly large visitor profiles.
