The old saying goes I wanted to know your stand on this. Has these high PR comment links benefited you in any way more than what Scrapebox has to offer? I have a bunch of these do follow links lying around that I collected and I have to go through them manually which will take me a whole load of time to go through and comment, placing my link one by one, whereas with SB, I could get thousands of links within minutes - although most are no follow. What is your opinion? Can Search Engines differentiate between a "placed" link (ie; comments, discussions) and an "authentic" link (Contextually placed in articles, referenced, etc) and do they credit them differently? Are these "artificially" placed links on high PR pages worth as much as gurus say they are? Comment!
