Yes, Virginia, There ARE Followed Wikipedia Links

Filed in SEO by Matt McGee on July 12, 2007 7 Comments

Fact: Outbound links on Wikipedia are nofollowed.
Implication: These links don’t pass “link juice” to the link recipient.
Result: When SEOs talk about getting links from Wikipedia, the main benefit that’s often mentioned is “it’s still a great source of traffic even if you don’t get the link juice.”

That’s true, but we’re overlooking one Big Fact: Wikipedia content doesn’t only appear on Wikipedia.com. It’s freely licensed, and liberally used by other sites.

And the external links aren’t always no-followed on those other sites.

Want an example? Here’s the “External Links” section of the Sears, Roebuck, and Company page on Wikipedia itself:

Wikipedia links no-followed

The links above are pink because they have the no-follow tag and I’m using Aaron’s SEO for Firefox extension.

Now, here’s the “External Links” section of the Sears, Roebuck, and Company page on Answers.com:

Answers.com links without no-follow

No pink. Cool, eh? :) That page on Answers.com is PR=4, which ain’t all that exciting … but you wouldn’t turn it down, would you? Of course not.

Now, just being happy you have a followed Wikipedia link isn’t enough. You have to help make sure that link holds some value. Here’s what you do:

1. Grab a bit of text from the page where your link is do a quoted search for it in Google. Here’s an example search with text from the Sears page. As you’ll see, most of the results are supplemental; if those pages have your link, I doubt there’s much benefit, if any.

2. So, if (when) you find a good result that’s not supplemental AND has the links followed, like the Answers.com example above, you need to help that page stay out of the supplemental. Give that page a link every now and then.

Conclusion: Links from Wikipedia probably are great for the traffic, but thanks to that content being licensed elsewhere, they can also be good for SEO reasons.

Needless to say, I’m not encouraging anyone to spam Wikipedia with links to your sites. No one with his/her head screwed on straight thinks that’s a good strategy.

    Was that page scraped before or after the nofollow rule was implemented on Wiki?

    Nevertheless, Matt, you know that everyone with a head screwed on crooked will now begin to mercilessly spam Wikipedia with links. :)

    Seriously, this a good find. You are turning over all kinds of interesting rocks this month (what with this, and the Google thing last week).

    Small Business SEM continues to be one of my top 5 favorite blogs! And you can quote me on that :)

    I don’t recall seeing any date stamp on the Answers.com page, everett, and without that, I wouldn’t have a clue how to know when they grabbed the content.

    I looked at about 6-8 sites that had used the Sears Roebuck page, and a couple had different implementations. One had the same 4-item list for “External Links,” but the links were missing — it was just 4 text items. On another, only one of the 4 items was there, and it was also unlinked.

    Sorry I don’t have a better answer for you….

    Miriam – thank you so much. :) But we both know that people started spamming Wikipedia long before I started writing about it….

  4. Nice article Matt!

    PS – Thanks for reaching out the other day. Looking forward to helping out your contact. Sorry I will not see you in San Jose.

    Warmest regards,

    Sean
