CiteScore Best Quartile†: This indicator shows the journal’s highest CiteScore ranking in a Scopus subject category (e.g., Q1 = 25% of journals with the highest CiteScores).

SNIP (Source Normalized Impact per Paper): This indicator is computed as the number of citations per article in the journal divided by citation potential in the field.

SJR (Scimago Journal Rank): This indicator is the average number of (weighted) citations in one year, divided by the number of articles published in the journal in the previous three years.
