1: Twitter; Put in your full bio and company URL. I have seen far too many profiles without links back to the company homepage. Send an email to all staff reminding them to so this.

2: Facebook; Ask all your staff to "Like" your page and to suggest it to their friends, the viral effect can greatly increase numbers. This profile increased Likes by 500 in two days which is a fantastic return. The restaurant can now directly market to 500 local people. www.facebook.com/cluskeys

3: LinkedIn; Again obvious I know, but an email to all staff making sure that their profiles point back to the company Website will reap some benefit.
