The bungalow belt and the Loop tower are two different patient books
Before anyone writes a keyword list, decide which of the two demand pools your practice is really serving.
Chicago dentistry splits into books that behave differently. A practice on a residential stretch of Ravenswood or Berwyn serves households living a few blocks away in bungalows and two-flats. A practice on an upper floor in the Loop serves people who work downtown and sleep somewhere else entirely.
The two books search differently. Residential patients search on evenings and weekends, often on behalf of a child or a parent, and they care first about who takes their plan. Downtown patients search midweek, want something inside a lunch hour, and will not come back on a Saturday for a cleaning.
Choosing badly is expensive. A downtown practice publishing family dentistry pages aimed at suburban households buys attention it has no schedule to convert.
Practices with a foot in both worlds need two content tracks, not one blended one. Put that split in the navigation, not in a paragraph halfway down the homepage.
