Presence measures the size of a university's web presence, including the number of web pages, subdomains, and rich files. Visibility measures the level of external impact of a university's web presence, including the number of backlinks from other websites. Transparency measures the level of open access and dissemination of a university's research output, including the number of files in academic repositories. Excellence measures the level of academic and research performance of a university based on the number of citations received.
The Webometrics Ranking methodology is unique in that it considers both the size and quality of a university's web presence. It also takes into account the open access and dissemination of a university's research output, which is becoming increasingly important in today's research environment.
