I am strongly believe that content is king! that's true and always true.
But the question is how is a good content? since sometimes this content works well with this kind of site, but not that kind of site.
Good content should be decide by Users! And therefore we are talking about User Satisfaction!

I should make my opinion clearer.

I means, for example if you are a news publisher. you'll update news, right? but what target users your website is targeting? they are white collar, or they are teenagers, or they are housewife? The fresh and unique content is kind of a must, but if you post the content relate to teen on a housewife website, does it work?

Just need to understand your users, who they are, what they expect from your website.
