One Wikipedia to rule them all

Johannes Beus
Russ Jones from thegooglechache.com has performed an interesting study: For 600 randomly chosen Wikipedia-pages he searched Google for the Title of the pages and recorded whether the page could be found in Google's Top10 – 580 of them actually did, which is 96,6 percent. Seeing that I am a fan of such studies, the data are derived from the English Wikipedia and the English Googleindex and the fact that I do not trust any statistics that I did not doctor myself, I decided to try this for 1000 randomly chosen pages from the German Wikipedia. To make sure the results are not distorted too noticeably, certain pages, which portrait certain “quirks” of Wikipedia (“list of foobar” and such) were not assessed:


We can nicely see that Jones evaluation is basically confirmed. It may be that only 84,7 percent of German Wikipedia-pages rate in the Top10 with their title, but even that is still enough. And to make sure that this article gets closer to SEO here the average number of backlinks which point to the pages:


Here we can see that pages which are up front certainly have more external backlinks, but the number of backlinks is not decreasing strongly – this is called Trust or Trustrank and is – not much of a surprise – arguably existent for Wikipedia.
