Most of us here know that submitting articles to places like ezine (or whatever, can't remember the one i use) is part of seo. My question is, are these articles that have been submitted unique or an article from your own website. I was thinking if there is 2 articles (one on your own website and the other on an ezine website) when spiders crawl the web and report back to search engines like google, wouldn't that have a negative effect?
