Scopus

Scopus offers three main journal metrics, CiteScore, SCImago Journal Rank (SJR), and Source-Normalized Impact per Paper (SNIP). These can be viewed by searching for your journal of choice and viewing the full source details.

CiteScore

CiteScore is a measure reflecting the yearly average number of citations to recent articles published in that journal. This metric is unique to Scopus. It is calculated by dividing the number of citations received by a journal in a given year by the number of documents it published in the preceding three years. It is updated annually and also tracked monthly. You can learn more about it here: CiteScore Metrics

SCImago Journal Rank (SJR)

SJR is a is a measure of the prestige of scholarly journals that considers the number of citations received and where those citations came from over a three-year period. It is based on the idea that not all citations are the same. The weight of the citations varies depending on the source they come from. This is useful to find out the prestige of a journal. The higher the value, the more prestige the journal is. It is calculated using this formula:

Source-Normalized Impact per Paper (SNIP)

SNIP is metric that measures the citation impact of journals considering the difference in citation practices across different subject fields. 

• SNIP > 1.0: The journal is cited more often than average for its field
• SNIP = 1.0: The journal has an average number of citations for its field.
• SNIP < 1.0: The journal is cited less often than average for its field

Scopus offers several metrics for each article. Scopus integrates data from PlumX Metrics as the primary source of its article-level metrics, along with traditional measures to present a richer and more comprehensive picture of an individual article’s impact. 

Citations

Scopus offers two citation metrics.

• citation benchmarking (percentile) - this calculates how citations for this article compare with the average for similar articles in the same field. 
• Field-weighted Citation Impact (FWCI) - this considers variations in research and citation behavior across disciplines

You can also view additional citation metrics by selecting "View Citation overview"

In citation overview, you can view the information in graph or chart format. You can even compare citation information across different documents. 

PlumX metrics

PlumX metrics provide insights into the ways people interact with individual pieces of research output. These metrics are found under each article in the "Impact" tab. 

• usage - number of clicks, downloads, abstract views, etc.
• captures - number of bookmarks, or expert saves
• mentions - This measures activity such as news articles or blog posts about research 
• social media - this includes tweets, Facebook “likes” and other social media posts that reference the article
• citations - offers a broader view of research impact beyond traditional citations.

Note: Not all articles will have all five.

Scopus generates an author profile for all authors. This compiles information on the author's impact, co-authors, topics, awarded grants, citation percentiles and trends, h-index, and much more. 

H-index

H-index rates an author's performance based on their 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. 

Scopus also provides an h-graph for each author. You can view this by clicking "h-index" on the author's profile. The h-graph is one way of displaying and comparing the productivity and impact of published work of scholars. To learn more about h-graph, you can do so here: How can I use an h-graph?

Citation Overview

Similar to article citation overview, author citation overview provides a detailed breakdown of the author's citations analytics. In each author profile, you can click on "citation overview" to view all the information.

Here you can view citation analytics of all the publications of that author. They are displayed in graph and chart format and can be manipulated by the user. 

Author Output

In each author profile, you can click on "analyze author output" to in-depth tools aimed to help users better understand an author's influence. 

Here you can find a collection of visual analysis tools designed to provide a better picture of an author's publication history and influence.
