Research metrics

Scopus combines its sophisticated analytical capabilities with its unbiased and broad content coverage to provide a comprehensive suite of metrics. When used correctly, these research metrics — together with qualitative input — give a balanced, multi-dimensional view for decision-making. Throughout Scopus, you will find metrics at the journal, article and author levels.

It’s time for a new standard of research excellence.

CiteScore™ metrics

Don’t Speculate. Validate

CiteScore™ metrics are a new standard to measure serial citation impact. Comprehensive, transparent, current and free, CiteScore metrics help you to analyze the impact of all serial titles – including journals – in Scopus.

Journal metrics

Researchers, publishers, bibliometricians, librarians, institutional leaders and others in academia have been exploring ways to bring research metrics into the 21st century by adding serial title-based measurements to an evolving and growing basket of metrics. CiteScore metrics now complement Source Normalized Impact per Paper (SNIP) and SCImago Journal Rank (SJR) metrics to provide more robust indicators for a serial title's performance on Scopus.

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): SCImago Journal Rank is a prestige metric based on the idea that not all citations are the same. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation.

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.

Additionally, you can compare total number of citations received per year, total number of documents published per year, the percentage of documents each year that have never been cited, and the percentage of documents published in the year that are review articles.

Article-level metrics

Article-level metrics (ALMs) quantify the reach and impact of published research. Scopus incorporates data from new sources (such as social media mentions) along with traditional measures (such as citations) to present a richer picture of an individual article’s impact.

The Article Metrics module on Scopus combines citation and alternative metrics in a new way to help you benchmark articles better. Use it to both determine which articles to read, and to gain deep insights into how an article compares with similar articles. On the Scopus article page, a sidebar highlights the minimal number of meaningful metrics a researcher needs, including (as available):

  • Citation count and percentile benchmark
  • Field-Weighted Citation Impact (FWCI)
  • Mendeley readership count and benchmark
  • Count of 1 type of scholarly commentary (e.g., blog posts, Wikipedia)
  • Count and benchmark of 1 type of social activity (e.g., Twitter, Facebook)
  • Total count of additional metrics and link to see breakdown by source

From the sidebar, clicking <View all metrics> opens the full Article Metrics module, providing an overview of all available metrics and the underlying content for further analysis and understanding.

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 records—provides the quality data needed to build accurate measurements of an author’s impact. With Scopus you can easily analyze and track an individual’s citation history. In addition to finding an author’s total citation and document counts from an author’s details page, you can also access the following metrics and tools:

h-index and h-graph: Rates a scientist's performance based on his or her career publications, as measured by the lifetime number of citations each article receives. The measurement depends on both quantity (number of publications) and quality (number of citations) of an academic's publications.

Citation overview tracker: An adjustable table that includes the number of times each document has been cited per publication year.

Analyze author output: A collection of in-depth and visual analysis tools designed to provide a better picture of an individual’s publication history and influence.
