Webometrics uses a number of criteria to come up with university rankings with the four methodology used to rank the university.
- Size (S). Number of pages recovered from four engines: Google, Yahoo, Live Search and Exalead. For each engine, results are log-normalised to 1 for the highest value. Then for each domain, maximum and minimum results are excluded and every institution is assigned a rank according to the combined sum.
- Visibility (V). The total number of unique external links received (inlinks) by a site can be only confidently obtained from Yahoo Search. Results are log-normalised to 1 for the highest value and then combined to generate the rank.
- Rich Files (R). After evaluation of their relevance to academic and publication activities and considering the volume of the different file formats, the following were selected: Adobe Acrobat (.pdf), Adobe PostScript (.ps), Microsoft Word (.doc) and Microsoft Powerpoint (.ppt). These data were extracted using Google and merging the results for each filetype after log-normalising in the same way as described before.
- Scholar (Sc). Google Scholar provides the number of papers and citations for each academic domain. These results from the Scholar database represent papers, reports and other academic items.
