There’s been some question about Wikipedia usage for the Best Exterminator on Earth 30 day SEO challenge. I’m not saying you can’t use the site for backlinks, visibility, or whatever, I’m saying wikipedia pages will ignored in the Search Engine Results Page.
The reason for this wiki ban stems from last years"World's Coolest Exterminator" competition.
As you probably now Wikipedia is a site with tremendous authority, so it ranks well in Google for just about everything.
So, I wrote an article on the site explaining the origins and rules of the World’s coolest exterminator competition. That article was crawled by web spiders, indexed and given the top position of Google within 20 minutes of the time I hit publish! Within another 20 minutes, the moderators killed the article citing, "Contest was not of significance". The search results, however, continued to give the dead article the top position for several days. When you clicked on the link, it took you to a "Page Removed" notification.
When this happened, I knew the site could be abused to win the contest. Simply submit an article 20-30 minutes before the competition ended and have a top ranking position. Sure the moderators would take the new "Best Exterminator on Earth" article down, but it would probably be alive at the time of the deadline.
And for someone, including myself, to employ that type of strategy would take the skill out of the contest and reduce it to an matter of timing - there’s really no fun in that. So, I hope that clarifies things.
