Digging a little deeper yields
Wikipedia is not a publisher of original thought
See also: Wikipedia:No original research
Wikipedia is not a place to publish your own thoughts and analyses or to publish new information not previously published.
You can read more
here, but it sounds like they're saying "Hey, no bullshit, ok?" So it kind of sounds like
this doesn't really live up to their criteria, but it hasn't been edited in almost two years, so who's really paying attention anyway. You are absolutely correct, by the way, in saying that all the external links are no-follow.
So let's try something else. A quick Wikipedia search of "SEO" brings up, well, a few different things. ("
Site Enhancement Oil, a liquid substance used by bodybuilders to increase the apparent size of some muscles" Who knew?) For now, let's just study the entry on Search Engine Optimization, since that's something we're probably a little interested in anyway. (Incidentally, I'm no expert so feel free to raise the bullshit flag if any of these assumptions are wrong.) The links within the main body of the article all point to other Wikipedia pages, so no link juice there. Scroll down and we see a Notes section. Click edit and we get
<!-- This is not the place to add your clever linkspam -->
<!-- Please post an explanation to the Talk Page before adding links here. -->
Below the Notes are External Links, and unsurprisingly upon clicking edit we're advised
IF YOU DON'T PAY ATTENTION TO THIS MESSAGE, YOUR EDIT WILL BE ROLLED BACK WITHOUT WARNING.
The External links section in this article is NOT an advertising section. THIS IS NOT A PLACE TO LINK TO YOUR SEO COMPANY. If you want to consider adding an external link please discuss it within the article's discussion page at
http://en.wikipedia.org/wiki/Talk:Search_engine_optimization. Please review the external link guideline at
http://en.wikipedia.org/wiki/Wikipedia:EL before posting in the discussion.
Okay, fair enough. Now that's not to say that if you wrote a good article that was somehow relevant to the main entry, you could cite it in either of these places along with a link. You might want to do your homework first. I'm not about to read their terms of use policy, but it's
here. I also understand that popular entries are being read, re-read and re-edited fairly constantly and consistently, so any links one might be able to sneak in wouldn't last anyway. Besides, if they're no-follow it's a pointless waste of time.
Honestly, I don't see how a Wikipedia entry would carry any more weight than anything similar, such as a posting on a message board. (No offense.) Exceptions being the highly coveted and authoritative sounding .GOV and .EDU domains. (Which, if you think about it, is ironic because nobody bullshits more than the government, and as for universities, well we all know how those crazy college kids are.) Leave Wikipedia alone, there are better and easier ways to get link juice.
