Any kind of language that creates distance between a business and its prospects and customers is a problem.
Put simply, you can’t turn a stranger into a customer by creating distance, by pushing people away.
Much of the time that distance is created by the language a company uses in its business and marketing communications.
First, overly promotional language creates distance simply by stimulating the reader’s defenses. Try to sell at me too hard and I’ll defend myself by stepping back, walking away or ignoring you altogether.
Secondly, overly formal, corporate language, filled with impenetrable jargon creates distance.
