I have been suggesting to buy blog posts with anchor texts to specific pages on website in order to boost SE rankings. I have spent $300 in 1 month buying 10 to 15 links per week from varying PR from blogs of the same niche. I have seen slight improve in SE rankings for the targetted keywords. My intention is to intensify this investment but before I would like your advice. I have been offered several offers to get links from blogs with content in the same niche with good PR 3-5 but when I check yahoo links they have 100 to 200 links most of them from same domain. Also I have noted that these blogs do not send any traffic since nobody sort of read them. They are like a modern web directory where people pay to get a blog post. My questions are these: 1. Is it right what I am doing? Should I continue buying blog posts from these blogs. As I told you they have nothing shady - its just I don't know how they get such high PR with so few links. 2. Does SE take into consideration traffic of linking sites? Since these blogs do not have any traffic - would they still help me. 3. Buying 10-15 links a week from varying PR in same niche - is it too much - would I get flagged? Thank you
