Most people around here who have autoblogs have duplicate content. It is very unlikely you have unique content unless you have some type of amazing rewriter which can rewrite your posts and make sense. Otherwise, most people have autoblogs that just fetch RSS feeds and let it do the work. My question is: What If you post a article or two every now and then mixed with the duplicate content? Say my "how to stop premature balding" blog fetches from 5 RSS feeds and today, I decide I want to write 1 or 2 good 500 keyword articles. How would Google look upon me? Do I gain very little or no SERP at all?
