Impact Factor of a journal helps you decide if has the credibility you are wishing for publishing your article.

Impact factor (IF) is a measure of average citation of an article in a journal per year. Hence, the higher the number of citations, the higher the ranking. So, IF can act as a powerful tool to compare journals by topic.

Clarivate Analytics annually publishes the journal’s impact factors as part of Web of Science citation reports. So, IF is only for journals listed in the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI).

Journals Impact Measurement

Use journal criteria to understand the impact of a journal:

CiteScore metrics

Helps measure the impact of journal citations. Free, comprehensive, transparent, and current metrics are calculated using Scopus data, the largest abstract and citation database of the literature reviewed.

SCImago Journal Rank (SJR)

SCImago Journal and Country Rank is a portal containing journals and scientific indexes of the country, based on information from the Scopus database. Scopus includes more than 15,000 journals from more than 4,000 international publishers and more than 1,000 open access journals. SCImago evaluates scientific journals in such a way that it weighs bibliographic citations based on the importance of the journals they have published, so that citations published by important journals are more valuable than those published by less important journals.

Source Normalized Impact per Paper (SNIP)

Source Normalized Impact per paper measures the effect of text citation by weighting citations based on the total number of citations in a thematic context. The impact of a single citation is more valuable in subject areas where quotations are less likely, and vice versa. Unlike the impact factor of popular journals, SNIP corrects differences in citation methods between disciplines, thus allowing for more accurate comparisons between citations.

Journal Impact Factor (JIF)

Clarivate Analytics provides the journal metrics of Journal Impact factor (JIF). It is the average citation number of times articles from a published journal in the past two years in the Journal Citations Report (JCR) year.


Although initially thought of as a benchmark at the author level, the H-index shows higher-ranking research publications, of an author. In fact, H-index deals with authors’ performance.
