Understanding Our Metrics
Article views: The total number of times an article page was viewed on our website.
Article downloads: The number of times an article was downloaded on our website. Note: PDF downloads are counted after July 10th, 2023.
Citations: The number of times an article is cited per Crossref data. Citations are updated every 24 hours. Crossref citations may differ from those provided by other services, as they only look for links between Crossref-registered works.
Online attention: The number of times an article is mentioned online (e.g., social media networks such as X, formerly known as Twitter, citations in public policy documents, mainstream media coverage), tracked by Altmetric. Scores are updated every 24 hours.
CiteScore (Scopus): The average number of citations received by articles in the journal over a four-year period.
SCImago Journal Rank (SJR): The average number of weighted citations in one year, divided by the number of articles published in the journal in the previous three years.
Source Normalised Impact per Paper (SNIP): The number of citations per article in the journal, divided by citation potential in the field.
Usage: The total number of times articles were viewed on our website in the previous calendar year.
