Condition pages are the entire lever here. Every complaint has its own questions, its own urgency and almost no competition, because most clinics publish nothing but a list of services.
Urgency is itself a search term. "Today", "this week", "seen quickly": someone in pain picks the clinic that names a free slot, not the one with the nicer photograph.
Because the search already has a price in it. «Custom orthotics cost» is not a browsing query: that person has already accepted they need them and is now comparing clinics. State the assessment, the wait and the figure, and the enquiry arrives from three towns away.
Diabetic foot care brings the steadiest patients of all. Those appointments repeat for years, and a clinic that explains how the checks work wins people who then never go anywhere else.
