Top 50 Universities ~ The Webometrics

The Webometrics Ranking of World Universities is produced by the Cybermetrics Lab (CINDOC), a unit of the National Research Council (CSIC), the main public research body in Spain. It offers information about more than 4,000 universities according to their web-presence (a computerised assessment of the scholarly contents and visibility and impact of the whole university webdomain).

The Webometrics Ranking is built from a database of over 15,000 universities and more than 5,000 research centers. The Top 4,000 universities are shown in the main rank, but even more are covered in the regional lists. Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not World-Class Universities.

I would say that looking at the top 50 universities, it is biased towards the US universities.
