CiteScore: is used as a standard to help measure citation impact for journal articles, conference proceedings and book series. It it is similar to impact factor used in Web of Science. This metric counts the citations received in a year to the documents published in the previous three years, divided by the number of documents published in 3 years.
e.g., a journal's CiteScore in 2020 = the citations it receives in 2020 to documents published from 2017 to 2019, divided by the number of documents published from 2017 to 2019 (indexed in Scopus) CiteScore Metrics include these 7 metrics:

SJR (SCImago Journal Rank): Inspired by the Google Page Rank algorithm, SJR is weighted by the prestige(quality, which is also determined by the number of citations) of a journal. SJR = Weighted citations divided by Number of published documents. SJR allows the user to compare journals regardless of their subject fields because it takes consideration of: quality of citing journals, different citation behavior across disciplines and self-citation. About SJR
SNIP (Source Normalized Impact per Paper): a weighted measure of contextual citation impact. SNIP = a source's average citation count per paper divided by the citation potential of this source's subject field. It considers a journal's likelihood of being cited, including:
SNIP allows direct comparison of journals across subject disciplines because citation impacts are normalized. The differences of journals’ SNIP are due to the quality of the journals but not the different citation behavior between subject fields.
Topic Prominence
Topics are based on clustering the citation network of Scopus content. Each Topic Topic is a collection of documents with a common intellectual interest and can be large or small, new or old, growing or declining in momentum. A document can belong to only one Topic). As newly published documents are indexed, they are added to Topics using their reference lists. These Topics are powered by SciVal and are now displayed directly in Scopus on Document Record pages along their prominence percentile score. You can click on the Topic label on Document Record pages to explore the Topic or open it in SciVal for further analysis.
Calculating a Topic’s Prominence combines three metrics which indicate the momentum of the Topic.
Topics are then ranked by Prominence of these citation patterns, which indicates a Topic’s momentum in a field of study. The development of Topic Prominence in Science is dynamically based upon extensive research and customer feedback.You can run a complete portfolio analysis to see which Topics your peers, competitors and benchmarking institutions are currently active in, and the related Topics of high momentum.

The Impact per Publication (IPP) is based on citations in one year to articles, reviews, and conference papers published in the preceding three years, divided by the number of articles, reviews, and conference papers published in those three years.
Field-Weighted Citation Impact (FWCI) score comes from the Scopus database and shows how the article's citation count compares to similar articles in the same field and timeframe. Field-Weighted Citation Impact is the ratio of the total citations actually received by the denominator’s output, and the total citations that would be expected based on the average of the subject field. You may view each article's FWCI at its full record page. More on Field-weighted Citation Impact (FWCI)
