Brand fragmentation
Six filler brands, six different shortlists
A patient asking for "Juvederm Voluma" gets a different AI answer than one asking for "dermal filler." Clinics with a single generic Fillers page are invisible on the brand-specific queries that make up most of the volume.
The audit measures coverage across brand × indication × city, and flags which comparator clinics are quietly capturing the per-brand citations you are missing.
