I was just brainstorming today, I figure that there are a lot of hard copy resources such as older books, magazine articles, etc. that someone could use to their advantage for putting up on their site. For example, say you are doing an article on a particular car model. You find an old magazine article associated with the car model, copy it down manually, find some keywords to optimize, and post. Now If this is already taken advantage of, I'm unfamiliar with the method. But I have some questions. 1.) I assume that Google's reach is limited to digital content and hard content that has been digitized. Certainly not all hard resources have been copied to the internet, especially if its older. How likely do you figure that Google wouldn't catch on to something like that, if at all? 2.) If workable, could this be a virtually unlimited resource for "fresh" content? I surmise that you would only have to adjust for keyword optimization and dated information?
