The website gap across Zürich, area by area
Zürich averages a 9% website gap, but it is not spread evenly. It runs from 23% in 8057 down to 3% in 8045. Areas with fewer than 25 checked businesses are left out — the rate isn’t meaningful there.
Areas without a link don’t yet have enough verified data for a page of their own; they get one automatically when they do.
