Fit problems are the opportunity. Wide, narrow, high instep, a bunion: those searches come from people who have wasted money repeatedly and will travel to a shop that solves it.
Children's fitting has a calendar. Before each school term and after each growth spurt, parents search for somebody who measures properly, and that visit repeats for years.
Brand searches convert. Somebody looking for a specific make plus a town has decided already, and a shop that writes its brands in text rather than showing logos appears for all of them.
Repairs bring people back. Resoling, stretching and re-heeling are searched all year, cost little and put a customer inside the shop where the new stock is.
