My questions today is, how much is a link from a do-follow post with PR6-7 worth if the external links from the perticular post are only 5-10, but still the overall external links from the blog are hundreds or thousands? SEO spyglass says they are worth 0.001 because it counts the overall external links from the blog but I think I do not agree here since the blog can be huge and can have more than 5000 pages...
