Most of you may have already found this... but I just found out about it this morning... very cool new tool from G in their Webmaster Tools site... They added a report to analyze all your external links to your site... very cool. Shows the number of links each page has, and which sites are doing the linking. It also can analyze your internal linking scheme as well... Check it out at http://www.google.com/webmasters/
Yes, very nice indeed. I got to know abt this from Matt Cutts blog. Checked it out and it seems really cool. However Matt says that not all links carry weights - here's the link to his blog post http://www.mattcutts.com/blog/google-provides-backlink-tool-for-site-owners/
