It is pretty obvious but how we act online should reflect how we act in real life. That means if someone shares or likes your posts or comments on social networks like LinkedIn it is polite to click 'like' or thank them in the comments.
Much like you would always react to someone who was nice to you or asked you a question face to face it is only right to do the same online. This is especially true if your interactions online are with your core audience of clients and prospects.
Some basic examples that come immediately to mind;
- Be approachable - connect with people you meet & those you work with
- Have a firm handshake, look them in the eye - Don't just make a connection, introduce yourself with a note
- Be gracious - if someone comments on one of your posts or connects with you - say thanks
