comparative analysis of Wikipedia’s appearance on page one of the search results shows Google favors Wikipedia far more than Bing. its interesting to see what can we learn about the search algorithms.
I'm not sure this kind of analysis can be accurate. There are so many factors involved in the display of search results that I doubt the accuracy of this kind of research. Having said that, I often get Wikipedia as one of the top 3 results when I search for something. Do you know where the original article appears? I would like to read it.
every search engine follows different algorithms to display search engine so it is quite obvious, there is no need to blame google about to be partial for Wikipedia, if yahoo indexes your site quickly and google does not then what will you say?, yahoo is partial for me..
