At the January Wikimedia Board of Trustees meeting in San Francisco I walked through a short presentation on comScore with additional info on international reach and on the portion of our traffic which comes from Google (PDF version, PowerPoint original). Contact me if you’d like any of the underlying data.
I updated the comScore data page with September 2008 information. comScore has made the first wave of changes we’ve suggested to improve their categorization of all of our sites/URLs, and as a result we now have some early estimates of traffic by the different language versions of Wikipedia.
UPDATE: moved to archive page.
One of the major online audience measurement companies, comScore, Inc., has generously donated access to its Media Metrix and World Metrix data sets to the Foundation. comScore has an opt-in panel of two million internet users around the globe and uses a range of statistical techniques to create an internally consistent portrait of the global internet audience.
One major area of work to do is reshaping the way comScore tracks our sites. It currently includes URLs that aren’t associated with the Foundation, and also is organized in a fairly haphazard way. This will take a few months to fix, but we should be able to drive much more useful info once the work is done.
