Guides: Journal Rankings, Citation Counts, ResearcherID, H-index and Altmetrics: Journal Ranking

Journal Ranking Metrics

Journal metrics use citation counts to rank journals in a discipline. Several methods have been developed to create journal rankings.

Journal Impact Factor - The JIF is a score representing the citation rate of the average article in a journal calculated over a two-year period.
CiteScore - CiteScore is the citation rate of the average article in a journal calculated over a three-year period. Unlike the JIF calculation CitesScore includes items published in the front matter of journals (editorials, letters, notes and short surveys) in the calculation of averages.
Eigenfactor Metrics - Eigenfactor scores use network analysis algorithms to measure the scholarly influence of a journal. Eigenfactors are calculated based on the citations received over a five year period.
Scimago Journal Rank - Scimago Journal Rank (SJR) scores use the Google Page Rank algorithm to weight the importance of source journals in citation counts.
Source Normalized Impact per Paper - Source Normalized Impact per Paper (SNIP) scores weight citations based on the total number of citations in a subject field.

Scimago Journal & Country Rank
The Scimago Journal Rank (SJR) indicator uses the Google Page Rank algorithm to show the visibility of journals in Scopus from 1996.
Eigenfactor.org
The Eigenfactor is a score developed by Bergstrom Lab at the University of Washington.. The Eigenfactor and Article Infuence scores measure the scholarly influence of scientific research findings. The website provides free access to Eigenfactor and Article Influence scores for 8,000 journals in the sciences and social sciences. The raw data used to compute the EF and AI scores are provided by Thomson-Reuters Journal Citation Reports (JCR) for each year 1997-2013.
