The Webometrics Ranking of World Universities, also known as Ranking Web of Universities, is a ranking system for the world's universities based on a composite indicator that takes into account both the volume of the Web contents (number of web pages and files) and the visibility and impact of these web publications according to the number of external inlinks (site citations) they received. The ranking is published by the Cybermetrics Lab , a research group of the Spanish National Research Council (CSIC) located in Madrid.

The aim of the Ranking is to improve the presence of the academic and research institutions on the Web and to promote the open access publication of scientific results.  The ranking started in 2004 and is updated every January and July. Today it provides Web indicators for more than 12,000 universities worldwide.

The Webometrics University Ranking is a ranking system based on university web presence, visibility and web access. This ranking system measures how strongly a university is present in the web by its own web domain, sub-pages, rich files, scholarly articles etc.  The central hypothesis of this approach is that web presence is a reliable indicator of the global performance and prestige of the universities and as such, is an indirect way to measure all the university missions (teaching, research, etc.).
