RustyBrick - a frequent poster on SEOChat and many of the other major search engine forums released a tool over the summer that conducts an advanced analysis of the links listed in Google's link command.

The link popularity analysis revealed some fairly interesting things. In addition to showing how PageRank is being passed, I discovered that several links which I presumed were not counted because of re-direct scripts actually have been counted by Google. If only Rusty could provide the same analysis for the Yahoo! linkdomain command...

p.s. Check out this new post for a more up to date view on Google's link command.
