Presumably the (external) sites you liked you have also. I sites from your Facebook feed after liking them, hence increasing their weight. As such I guess the answer for small businesses is simple - you need an engaged audience and then Facebook is another way to reach that engaged audience.

Thinking if Facebook as an advertising medium is IMO wrong - it's like an email list to people who don't check their email.

Of course the problem is now how do you reach potential members of your audience before they become engaged?
