I need to do something about my backlink sad state affairs. I see offers in the link sales section where you pay $X for inclusion on 600 blogs. How beneficial is this? I see the blogs and the pages are just littered with links, can anything good come from this or is it a waste of money ?
popular blogs can help drive traffic to your site as well as raise your PR and investing on them can be worthwhile. after all blogsvertise, pay2blog, payperpost and other pay to blog site will not exist
they will help to get more traffic but they will not help your seo. i think google may filter them because of duplicate content
You end up being moved to a PR 0 page in the archive, and the blog is often some obscure site no one see. Even if Google gives it the Full value, there is not much to be received from a link that is PR 0 and will likely never change. I think you are better off looking for blogs where the owner really care what is on his site (not going to happen if he has 100 blogs to keep track of). There will be far fewer out going links and what you get will likely be of value.
