I'm a professioanl writer and run an informational website so when i started up 2 years ago i assumed i must be onto a goldmine as everyone kept talking about how content is king.
So there i was, waiting for all those natural, organic lnks to come rolling in. I was waiting for a long time.
Recently I had an epiphany on the matter. It's not good content alone that draws links, it'a authority content. If you have one really funny article about buying widgets in Peru then yes, it may be a good read but who's going to link to it?
If on the other hand you get a criticall mass of content together about widgets in peru, their history, their production, the culture of the users, the types of widget available - in short, more information about widgets in peru than a reader could digest in one visit - then people will consider your pages to be a resource and will bookmark and link to you.
Content needs to be well written but that isn't enough. It needs to belong to a larget section of content that has authority status in the eyes of the user. Take every angle of your subect and write separate articles and guides about it. You might think you're repeating yourself at times but to someone researchign the topic, all good info available is manna.
