I've searched for videos on how to effectively manage FB pages for business marketing purposes and it seems all I find are drips and drabs

Still new to the game, I'm looking for no-cost recommendations. With the basic setup complete.

I have reviewed much/most on the FB site for getting started, but I'm really not seeing how it all ties together. Maybe its me.

For example, what does it really mean to assign someone an administrator (such as after they 'like'), subscribing vs liking the page, working lists and groups, the implications of the 'share' option, and much more.

I have no compiled list of friends, and so I'm delving into other FB pages, initiating with comments and likes, as my associated website is low in traffic in terms of potentially bringing FB engagements. Though Twitter account activity is beginning to pick up steam.
