Wikipedia Links No Longer Passing PageRank
SEJ reports that Wikipedia has gone ahead and added the NOFOLLOW attribute to all external links, effectively dismissing any link-juice value from Wikipedia links.
While marketers may still benefit from the actual link traffic, this marks the end of receiving any PageRank value from the highly-respected resource.
So, in response, any future links to Wikipedia from us, will include a NOFOLLOW. Maybe if we all take that approach, Wikipedia will lose its PageRank and won’t have to worry about link-spam any longer.
