Research metrics

Research metrics give a balanced, multi-dimensional view for assessing the value of published research. Based on the depth and breadth of its content, Scopus works with researchers, publishers, bibliometricians, librarians, institutional leaders and others in academia, to offer an evolving basket of metrics that complement more qualitative insights. Throughout Scopus, you can access multiple metrics at the journal, article and author levels.

Journal metrics

Journal level metrics continue to be an important part of the basket of metrics, complementing new and alternative metrics to provide a multi-faceted view of a journal’s impact. On Scopus, you will find an evolving and expanding suite of journal metrics that go beyond just journals to include most serial titles, including supplements, special issues and conference proceedings. Freely available on Scopus you will find CiteScore metrics (NEW), SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP).

CiteScore metrics: A family of eight indicators that offer complementary views to analyze the publication influence of serial titles of interest. Derived from the Scopus database — almost twice the size of the next-leading abstract and citation data provider —  CiteScore metrics offer a more robust and accurate indication of a serial’s impact.

SCImago Journal Rank (SJR): A prestige metric that can be applied to journals, book series and conference proceedings. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation.

 Show more

Source-Normalized Impact per Paper (SNIP): Measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa.

Article-level metrics

Article-level metrics (ALMs) quantify the reach and impact of published research. Scopus now integrates data from PlumX Metrics as the primary source of its article-level metrics, along with traditional measures (such as citations), to present a richer and more comprehensive picture of an individual article’s impact.

Author metrics

Scopus bibliometrics can help you assess an individual author’s research output and scholarly impact. The depth and breadth of content on Scopus—which includes 2.5 million pre-1996 recently added record—provides the quality data needed to build accurate measurements of an author’s impact.
