Parish is the word, and county is the tell
A dental page that says county was written by someone who has never worked here, and patients in Jefferson Parish read it that way inside a sentence.
Most practice sites run on vendor boilerplate. The service area line says county. The about page says greater metro area. Neither phrase belongs to anybody who lives in Orleans, Jefferson or St. Tammany Parish.
Louisiana breaks national templates in larger ways too. State law here descends from a civil law tradition rather than the common law used in every other state, so generic national content on anything legal tends to be wrong here rather than merely vague. If a vendor cannot get parish right, treat the rest of what it wrote about Louisiana with suspicion, and take any legal question to your own counsel.
Rewrite the service area language before you write anything new. Name the parishes. Then name the places patients use out loud: Uptown, Mid-City, Lakeview, Gentilly, Bywater, Metairie, Kenner.
Some patients search a parish name. More search a neighborhood. Both belong in the visible text of the page, in the headings, and in the title, not baked into an image a search engine cannot read.
