Article metrics can be a useful way of understanding the impact and influence of an article. The “Metrics and citations” menu on the article page brings together a number of different measures to help support citation analysis.
Why does the number of citations sometimes differ between services?
The metrics provided by different services may differ because each are based on different sets of data sources depending on the main purpose of that particular service.
Web of Science
The Web of Science citation results displays the number of times the article has been cited by other resources across all indexes in the Web of Science platform.
The citation results figure for Web of Science is automatically updated daily.
The Crossref cited-by count displays the number of times the article has been cited by other resources registered on Crossref.
The cited-by count is automatically changed shortly after new citations are processed and updated on the Crossref database.

The scite badge displays the number of times the article has been cited by other resources indexed by the service. The scite database contains 2b references, 1.2 billion citation statements, and metadata for over 180 million articles. To learn more about scite coverage, click here.
scite also uses a deep learning model to provide a classification for each citation. This classification gives additional context, indicating if the citation offers supporting or contrasting evidence or simply mentions the referenced work.
The figures on the scite badge are updated dynamically as new articles are processed by scite.
scite is currently being piloted for a select number of titles on Sage Journals.

The Altmetric Attention score is an automatically calculated, weighted count of the attention an article has received from a variety of different online sources.
The colours of the “donut” around the score represent the proportion of the article’s attention that comes from different sources.
The Altmetric Attention score is updated in real-time. Detail on the frequency of updates from the different data sources can be found here: https://help.altmetric.com/support/solutions/articles/6000240275-attention-sources-update-frequency-and-collection-methods
