Example I have 100 web 2.0 with same niche (computer example). My site (with computer niche) has 10 posts which focus on 10 keywords. (and more post will be added in future) So if I make 100 backlinks for each post from these 100 web2.0s, will that hurt my site. Suppose anchor text variation is good, 10 backlinks per day for each post, no proxy. Please give your opinion, thank you.
