Journal metrics are a proxy measure used to evaluate the relative importance of a journal and identify major journals within a
special field of study.
The most commonly used metrics are: Journal Impact Factor (Clarivate Analytics), SJR and SNIP (Scopus), SCImago SJR
Google Scholar Metrics.
The Journal Impact Factor is the average number of times articles from the journal published in the past two years have been
cited in the JCR year.
The Journal Ranking shows the ranking of the current journal in its subject categories based on the Journal Impact Factor.
- Citation data only for the records indexed by JCR.
- Limited number of small-sized journals.
- Limited number of journals in non-English languages.
- Very few open access journals.
- New journals do not have Journal Impact Factors.
- Disciplines that use more references per paper is expected to drive up the Impact Factor of the journal.
- The same journal may be ranked differently depending on the category being reviewed.
Large and small journals are compared equally *Smaller or more specialized journals will tend to have smaller Impact Factors.
