I know that's possible because I've seen it a million times here on the forums. It's amazing how when put on the spot, all my "learnings" went straight out the window.
I know how to create the QR codes and direct them to do just about anything -- but where is the easiest or best place to leave reviews? Direct them straight to the client's site? Or to a landing page and then have someone manually enter the reviews / citations?
While I'm doing my own research, any suggestions, resources, WSO recommendations or pointers that you guys could add here would be a blessing!!
