Although it’s not as fashionable as it perhaps was a couple of years ago, getting a link from Wikipedia is still a pretty hot topic. I still frequently hear, “I need a Wikipedia link. How do I get one?”
I’d debate whether anyone actually needs a link from Wikipedia, or any specific site. A single link from a single site, no matter how powerful, is never the be all, end all of link building. But if you’re determined, just how do you go about getting that link?
There’s no simple trick.
Wikipedia Links: Are They Worth It?
All links on Wikipedia have the nofollow attribute. According to Google’s official policy, nofollowed links don’t pass PageRank and don’t carry anchor text metrics.
However, there are a bunch of link based metrics that they could be carrying, such as domain authority, domain diversity, etc. Without getting into a massive debate on the merits (or lack thereof) of nofollowed links here, suffice to say that nofollow links carry some algorithmic SEO value. So from that perspective, links from Wikipedia do carry worth.
It’s also interesting to note that in this video, Matt Cutts, in his usual carefully worded terms, voices some frustration that all Wikipedia links are nofollowed, as many of them, especially from trusted editors, would actually be useful to Google’s algorithms.
I don’t think it’s a big leap to imagine that Google does make some use of these links (no matter what Matt says), even though they can’t use the PageRank and anchor text metrics.
In addition to any algorithmic SEO benefit you may or may not get from Wikipedia links, there’s also direct traffic and plain old brand and content exposure.
So, in theory, yes it’s worth getting links from Wikipedia — even if they aren’t the most powerful links in the world. The catch is whether you can get one or more easily enough to make it worth your while.
