And the flip side - if you're accepting guest posts, don't be ridiculous with culling out the links. We recently spent 8 hours researching and writing a guest blog post that contained 2 links back to ours. Both completely in context. One was removed, and the other was modified so that noone would want to click on it. No bio link either.It was a complete waste of our time. Guest blogging is a 2 way street. Yes, you should demand high quality content. When you get it, don't be a douche.
