A common marketing mistake, is using the wrong language with clients.

An example of wrong language is the flight information provided by the captain over the intercom: “Our aircraft is flying at 625 knots Indicated Air Speed“ Knots? I can barely convert miles to kilometres. Air-speed? I would rather know the aircraft speed.

I would recommend not to use techie jargon with your clients. Fit with your client’s measurement system, or s/he will continue to nap.
