Webometrics Ranking is a methodology used to rank universities and research institutions based on their web presence and online impact. This ranking system was first introduced in 2004 and is maintained by the Cybermetrics Lab, a research group of the Spanish National Research Council.

The Webometrics Ranking is a unique and innovative ranking system that considers the web presence of universities and research institutions. It takes into account various web-based metrics such as the number of web pages, the number of backlinks, the number of citations, and the number of files in academic repositories. The ranking is updated twice a year and covers more than 30,000 universities and research institutions from around the world.

The significance of the Webometrics Ranking is that it provides an alternative and complementary approach to traditional ranking systems. It allows universities and research institutions to assess their online presence and impact, which is becoming increasingly important in today's digital age. The Webometrics Rank Service Ranking also provides valuable insights into the performance of universities and research institutions in terms of their online visibility and impact, which can be useful for academic and research purposes.
