Until recently, the University of Zurich had two Internet addresses (URLs). Webometrics' assessments are, however, based only on a single address, which led to a much poorer showing than would be expected from UZH's presence in the Internet. After harmonizing the URL addresses in 2012, the University achieved a better ranking.

In this assessment, it is important to note that the indicators mainly assess the quality of an institution's presence in the Internet. Certain aspects that are otherwise considered in rankings – for example, non-online publications – were given little consideration, while others – such as teaching, awards, third-party funds – were left entirely out of the equation.
