Put a QR Code on the Truck. Just Don't Point It at Your Homepage.
A truck QR code gets one curious moment from a person standing on a sidewalk. Send that scan to a page built for the moment, with one job, a call button first, and tagging so you can see what the truck earns.
Want a page built for the code on your truck, one job, a call button first, and tagging that shows what it earns? I build that as part of a website job for Missoula trades and service shops.
