Wikipedia Conquering Google First, World Next?

by Terri Wells, SEOChat

If you’ve been using Google to search for just about anything lately, you’ve probably noticed a strange trend: entries from Wikipedia appear at or near the top of the first results page. What’s going on here? Is it something we should worry about? What, if anything, should you do about it for the sake of your web site?
The first thing you should know is that you're not imagining this trend. Hitwise recently reported that Wikipedia's share of Google downstream traffic has gone up 166 percent over the past 12 months. Wikipedia receives 70 percent of its traffic from the search engines. Google by far is the largest source of search engine traffic for the online encyclopedia anyone can edit; half of Wikipedia's visitors show up as a result of being referred from Google. {more}
