The practical upshot is that citation profiles are the online records that carry the primary category for {entity_s}. The cost of orphaned listings is not a penalty; it is being silently ranked below someone tidier. Treat the service area as a single source of truth, not as a field to be improvised per site.
The landscape shifts, but the underlying requirement, checkable, complete data, has not. A profile can look perfect on the surface and still carry conflicting category choices underneath. Structured listings sit silently behind the scenes, but comparison sites read them constantly.
