Being too formal
Audiences want to interact with real people, not with machines – if you communicate in an overly dry and formal way, you will only turn people off. So don’t sound like a robot, be a person. Don’t address people with formal phrases such as dear sir/madam – write their names instead. They will appreciate it and feel comfortable if you show them how approachable you are.
Of course, you should remain professional, but write in an upbeat tone and add a personal touch. Use casual vocabulary and a little humor, as if you were speaking with friends. To succeed on social media, your brand must be easy to relate to.
