Author level metrics help to measure the citation impact of an individual.

h-index: An extremely popular indicator, the h-index is named after J.E. Hirsch, the author who introduced the metric in his seminal 2005 article. The h-index is equivalent to the number of h publications by an author that have been cited h number of times. The h-index can be located in several places in Scopus.

You can find the h-index in the results list of an author search.

You can find the h-index on an author profile page.

You can find the h-index from a list of documents by selecting all documents and clicking on the citation overview button.

Article level metrics attempt to measure the citation impact of a single paper or a group of papers.

Citation count: Citation count is the number of times an article is cited in other bodies of literature. The citation count can be found on the document details screen.

Field-Weighted Citation Impact (FWCI): The FWCI is the ratio of the total citations a document has actually received by the denominator's output, and the total citations that would be expected based on the average of the subject field. A value greater than 1.00 means the document is more cited than expected. You can find the FWCI on the Documents detail page or on the View all metrics page.

Alternative Metrics: Alternative metrics are available via the aggregator PlumX Metrics. Alternative metrics provide information about online attention a document has received, including usage counts, capture counts from reference managers, mentions in news media, blogs and Wikipedia, and social media shares on platforms like Twitter and Facebook. You can find the alternative metrics in the Metrics box on the right-hand side of the screen on the Document details page, or by clicking the View all metrics tab.

Journal level metrics attempt to measure the citation impact of journals themselves. By clicking on the journal title in the document details page, you can see several journal level metrics.

CiteScore: The CiteScore is equivalent to the number of citations to documents (which includes articles, reviews, conference papers, book chapters, and data papers) by a journal over four years, divided by the number of the same document types indexed in Scopus and published in those same four years.   

SCImago Journal Rank (SJR): The SJR measures weighted citations received by the serial. Citation weighting depends on subject field and prestige of the citing serial. 

Source Normalized Impact per Paper (SNIP): The SNIP measures actual citations received relative to citations expected for the serial's subject field.
