I saw a story on the internet a few months ago. It was about a world famous violin player. He is like the top violen player in the world or something to that effect.
He put on raggy clothes and played his instrument on the NYC subway station. Nobody really paid any attention and just treated him as any other performer who plays in the subway.
My point is, this is a lot like content. You can have the greatest content in the world written by the greatest writer. The fact of the matter is google does not know that. Sometimes its sad, but that content needs to be performing at a large theater which in our case would be a very high authority website.
