Some good insight above. @annliu states it well.
Mainly, you want quality that grows organically. Concentrate on quality posts that reach your fans and trigger response, and you will build that fan page with many engaged fans.
It is a process that requires planning and diligence. But it is great when achieved! 
Hope that helps.
