You can use your facebook for posting site news, or questions/pictures/competitions to get your customers interacting. Personally I don't think facebook works well as an acquisition tool but it can be good for retention and keeping your visitors engaged.
There is a great tool (free) Hootsuite, it allows you to schedule all your social media posts and post on multiple platforms(facebook/twitter). So you can set up a weeks worth of posts, and they will go out day by day or however you want to set them. I find it quite useful, as sometime it can be difficult to remember to post everyday/regularly but if I dedicate sometime once a week I know I'm set for a while.
