The leak
Eight treatments can’t share one page.
The Botox patient and the IV therapy client aren’t searching for the same thing.
A med spa’s range is an asset in the treatment room and a problem on the web. Someone looking up Botox in Warren has different questions than someone comparing IV drips, and neither is well served by a page that mentions everything in a line.
Search engines see it the same way. One general page gives Google nothing specific to return for “lip filler near me” or “B12 injections Detroit,” so the spa competes for none of those searches.
So the brief was a site sized to the real menu: a page for each treatment, a page for each drip, articles for the questions that come before booking, and a Book Appointment button everywhere a visitor might be ready.
