LISTEN: Always pay attention to what people are talking about in your market. You can set up alerts for this!
INTERACT: Build trust around you. After you listen to people’s problems interact with them and try to offer them a solution.
LISTEN SOME MORE: See if your actions were successful.
PROVIDE QUALITY: Be a constant provider of quality information: either content or suggestions (tips, advice)
BE READY TO MANAGE CRISIS: You have to expect that not everyone will like you and be positive about your brand. If someone is negetive, it's a good idea to already have a plan in place of how to react.
BE THE STARTER: Sometimes start conversations.
DONT SPEAK BADLY OF ANYONE: eventually it will turn against you.
BE SINCERE: This is valid on all social networks. If you are planning to post direct sales make it clear in your profile. Otherwise people will start to ignore you.
NEVER SPAM.
ADD SOMETHING: If you are entering a conversation add something to it.
