If you think of your content as a pyramid, the broadest coverage of the topic should be listed first. Then move on to more and more specific as you get further into the page. This is useful to your readers, as they can stop reading and move onto something else once you've gotten as specific as they need. And the more useful you are to your readers the more they will want to read your content.
In this day and age, it is by far the one of the hardest tasks to do online always coming up with fresh content for Google to devour. I love how easy Spin Re-Writer makes it for online marketers to get on with their business and not have to worry about the big G penalising their sites. Of course it's not just about fresh content, but it is certainly a big factor. Thanks Aaron and the team...:)
