A dentist two subway stops away beats one two miles away
Distance here is counted in blocks walked and stops ridden, so a keyword map built on driving radius describes a city that does not exist.
Dental SEO advice written for the rest of the country assumes a car. It assumes a fifteen minute drive, a parking lot and a service area drawn as a circle. None of that survives contact with the five boroughs, where a patient in Astoria will walk past four practices to reach the one near their train and a patient in Park Slope will not cross the park for a cleaning.
So the query list starts with how people actually move. Neighborhood plus procedure. Neighborhood plus plan. Nearest-station phrasing, which people use more than marketers expect. Hours phrasing, because a practice open before nine or after six is answering a different search than one open banker's hours.
Recall and hygiene searches are hyper local and always will be. Implants, full-arch work, orthodontics and cosmetic cases travel further, and they will cross a bridge. Those two groups deserve separate pages with separate geography, and putting them under one Services dropdown wastes both.
Write down the six or seven places your existing patients actually come from before writing a single page. The list is usually shorter and stranger than the owner expects.
