FaceBook Advertising Help

[Craig Haskell]

I have a free real estate education website, called Value Hound Academy.  I have built up the following organically to a fairly large audience over the years.  We are having an education event coming up that for beginner investors and I want to advertise it to FaceBook and we have never paid for advertising before but keep hearing about FB advertising.  Anybody, have any tips on what the best way to do this is?  I know it's hard to just sell tickets so I was thinking about giving away some of the tons of articles, videos and such instead.  Anyone have any luck with FB sponsored ads?  What works...what doesn't?  Thanks!
