Hey guys, I found a handful of .edu sites which auto approve your comment. PR ranges from 5 - 8. I was wondering if it helps my SEO if I post my link with KW as name in an old post of the .edu site, like 2010. I realize it has to be recrawled, how would I get G to crawl the link? And what are the backlinks worth to my SEO anyways? Thanks in advance. EDIT: What would happen if I post a couple dozen or so comments to one single blog post? Different anchor and URL..
