Hello There, I just found a way to get around 100 PR 5-8 contextual links from authority sites. These sites are already ranking on top 50 of many popular keywords. But the problem is that the links are no-follow. So, If I just use these no-follow links. Will my site rankings increase? [Can any big jump be expected?] Btw, It takes some time to get one link from these sites. [Around 1-2 hours] So, Should I make effort to get no-follow backlinks or not? Thanks for your help. Edit: I forget to mention that PR 5-8 is PR of the website. Not the webpage in which my link would be placed.
