Journal ranking is widely used in academic circles in the evaluation of an academic journal's impact and quality. Journal rankings are intended to show the place of a journal within its field, the relative difficulty of being published in that journal, and the prestige associated with it. There are several journal-level metrics, most citation-based.
Use index databases Scopus and Web of Science to find journal ranking and prestige of scientific journals.
Impact Factor (ISI Web of Science)
Impact factor measures the number of times an average paper in a particular journal has been referred to. In any given year, the impact factor of a journal is the number of citations, received in that year, of articles published in that journal during the two preceding years, divided by the total number of articles published in that journal during the two preceding years.
CiteScore (Scopus)
CiteScore is a simple way of measuring the citation impact of serial titles such as journals. Serial titles are defined as titles which publish on a regular basis (i.e. one or more volumes per year). CiteScore calculates the average number of citations received in a calendar year by all items published in that journal in the preceding three years.
SCImago Journal Rank (Scopus)
SCImago Journal Rank - the citations are weighted, depending on the rank of the citing journal.
Immediacy Index (ISI Web of Knowledge)
The Immediacy Index of journal is the number of citations the articles in a journal receive in a given year divided by the number of articles published.
Source Normalized Impact per Paper (Scopus)
SNIP corrects for subject-specific characteristics of the field someone is publishing in. This means that, contrary to the Impact Factor, SNIP numbers can be compared for any two journals, regardless of the field they are in.
h-index
It is a metric for evaluating individual scientis. The h-index is the highest number of autor's articles, h, that have each received at least h citations.
