SearchKing has regained its PageRank valyue for its Web site, after a four year penalty. The Search Engine Watch Forum thread, Four Years Later, SearchKing Regains Google PR has Danny Sullivan providing the historical guide as to explain why this is important. In November 2002 Google was sued over PageRank decrease by SearchKing. Since then the PageRank value came back but soon went away. SearchKing case was the first of its kind.
Bob Massa, owner of SearchKing, is a frequent visitor of Search Engine Watch Forums. I would not be surprised to hear a comment from him at Search Engine Watch Forums. Also, on a professional note, he is a wonderful person to work with.
