Can a link to my website from Wikipedia hurt my PageRank at Google?
Jun 29th, 2009 |
A lot of questionable websites use content from Wikipedia. These sites would also link to my website.
Since WikiPedia is a public space, which can be spammed, WikiPedia makes all outgoing links “nofollowed” meaning there is no “PageRank juice” which flows outward.
As long as your link profile is solid, a link can’t hurt you. If it could, you could focus on bad links to your competitor’s sites.

No, Wikipedia makes no difference to PR of linked pages, either positive or negative.
This is intentional on Google’s part - they have announced this (see somewhere in the Google blog). This is to discourage low quality links from being added to Wikipedia articles.
