I'm building a new site at the moment, I've never blogged before and I'm not sure what the best practice is with regards to blogging or not. If I have a blog on my site and update it with an article I've written but also give that article its own domain such as mysite.com/article will that affect my ranking with Google because their algorithms assume I'm duplicating content? I'm planning on adding a new article once or twice a week, should I just scrap the blog and continuously update my site once a week with an article with its own domain and e-mail users about it?
