you'll need to establish yourself as an authority.
Are you talking about site's authority or own authority.
From what I read, you mean both but more emphasis on building your own name brand (Which is kind of becoming a celebrity.)
In both cases, I think you have to earn/win it rather than working outside to get it.
However, talking about own name, I have seen many people who are doing very well on twitter and Facebook, they have "a recognized name", but most of them have an awful sites. Only tiny % get decent traffic.
