Dental searches mix very different moments. A cracked molar on a Saturday means the person wants a phone number and an opening today. A search for clear aligners is a slow comparison that can stretch over weeks. Whitening, veneers and implants attract shoppers who read reviews, look at before and after galleries and ask about financing. When one campaign catches all of it with a single ad and a homepage link, the algorithm drifts toward whatever converts most easily, usually quick cleaning inquiries or calls from people outside your area.
Queries that look relevant but never book
Terms like dental school, dental assistant jobs, free dental clinic, dentist wages and DIY tooth remedies slip into broad match traffic constantly. So do searches for a specific competitor by name and for insurance plans your practice does not accept. Without a careful negative keyword list and regular search term reviews, a large share of clicks goes to people who could never become patients.
