Yes, this post on SEOmoz is all about their Linkscape product but you could pretty much ignore most of the post and head for the first tutorial video halfway into the post and get a primer on how links work, their importance to search engines, and how search engines dissect links and their distribution. A lot of it is basic stuff but it’s presented here in a well put-together conversation.
The second video does get into fully-qualified domain and pay-level domain discussion which had some value in it. The third video starts getting into mozRank (SEOmoz’s “page rank” equivalent) and despite being informative starts getting hairy after a little while. Perhaps if it was broken into two shorter videos (vs 19 minutes) that were a bit better organized.
Still, these videos are part of an education series by SEOmoz and I hope they keep it up! Very helpful!
