I recently got an offer to post an guest blog, with link to their site, on my PR 0 autoblog site. I accepted the offer and got $10 for that. Plus $12 for 1000 words article (-$9.5 for outsourcing it). But the thing is i really do not understand why would someone pay for this? From my SEO knowledge there is almost no value of such link. Is my SEO knowledge that bad?
