A couple of years ago on a different blog I wrote an article talking about re-purposing blog posts. That post was more about internal linking by making sure to take old blog posts and add those links to newer posts to help enhance the SEO benefits of new content.
In this instance the concept of re-purposing content is more than talking about blogging. Most people have something that they’ve written previously somewhere on their computers. What they forget is that much of what was already written would make great blog posts or articles to put on their websites. If you’re looking for a lot of content and don’t have the time to write something new, going back through old files could provide you with what you need.
