Hello all, say I have an article with a anchortext keyword in it and I submit it to 30 article sites. Will this have a negative effect on my keyword ranking? Should I aim to have more articles instead of submitting just one to ' too many ' sites? I know having duplicate content on your own site is bad and that you best have new material on it, but what about duplicate articles on other sites that link to my site? What's the right balance here?
