• Visibility; external networks linking to webpages; data derived from Majestic (50% weighting)
• Transparency/Openness; number of citations from top 310 authors (excluding top20 outliers); data derived from Google Scholar (10% weighting)
• Excellence; number of papers in top 10% most cited in 27 disciplines; data provided by Scimago from Scopus (40% weighting).
