Scopus Sources provides three main journal level metrics: CiteScore, SNIP, and SJR

CiteScore

CiteScore (developed by Elsevier) is the main journal-level metric used in Scopus although they do include other metrics in the database. The CiteScore of a journal is calculated annually for the previous year.

The CiteScore for a year is the average number of citations received in 4 calendar years to 5 peer-reviewed documents types (research articles, review articles, conference proceedings, data papers and book chapters) published in a journal in the same four years.

 

To locate the CiteScore search for the title in Scopus under Sources. The journal’s profile page also includes a CiteScore Tracker for the current year and tab of rankings based on CiteScore. This metric should not be used to compare journals in different subject fields.

Source Normalized Impact per Paper (SNIP)

This is a measure developed by the Centre for Science and Technology Studies at Leiden University (CWTS) of actual citations received relative to citations expected for the serial’s subject field. The SNIP is field-normalized and can be used to compare journals across subject fields.

SCImago Journal Rank (SJR)

This metric was created by the SCImago research group from the Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares, dedicated to information analysis, representation and retrieval by means of visualisation techniques.

The SJR is a prestige metric which uses an algorithm similar to Google PageRank and the subject field, quality, and reputation of the journal have a direct effect on the value of a citation. The average SJR value for all journals in Scopus is 1.000
