1) PRESENCE: The global volume of contents published on the university webdomains as indexed by the largest commercial search engine (Google).
2) OPENNESS: The global effort to set up institutional research repositories is explicitly recognized in this indicator that takes into account the number of rich files (pdf, doc, docx, ppt) published in dedicated websites according to the academic search engine Google Scholar.
3) EXCELLENCE: The academic papers published in high impact international journals are playing a very important role in the ranking of Universities.
4) IMPACT: The quality of the contents is evaluated through a “virtual referendum”, counting all the external inlinks that the University webdomain receives from third parties.
