Yes. Optimizing by persona will not hurt visibility, even for non-logged-in users. In these cases, AI models still utilize session data, such as language, location, and system defaults, to shape answers, so persona alignment can influence the tone and phrasing within that single response.

This makes persona-driven optimization a powerful lever for driving long-term visibility and brand alignment.
