I recommend you make a fan page, then advertise your fan page. You can offer a free gift for people to become fans of your page. You will get more fans that way. Also, you can use a more general keyword - for example, if your village is in Los Angeles, then your keyword will be "los angeles". also you will target los angeles residents. Hope this helps.
I recommend giving a free gift to people for inviting their friends. Then put a link in our group to your website or fan page. You will get more members this way. Hope that helps.
Yeah, I've been having some issues with Facebook's keywords also. I have tried being patient but sometimes it works better if I close all my browsers and then go back and try again. I think for me it's more of a javascript issue though.
