(29 Aug 2023) PlumX Metrics are a primary source of article metrics on Scopus, providing insights into the ways people interact with research output in the online environment. By categorizing the metrics into five categories – Usage, Captures, Mentions, Social Media, and Citations – PlumX helps make sense of a large amount of metrics data and enables analysis by comparing metrics that are compatible.
Due to changes in market conditions, on 31 August 2023, Twitter metrics will no longer be included in PlumX Metrics.
With this change, Twitter tweets and retweets will not appear in the Metrics section on the Scopus Document details pages. Twitter data will also no longer be available via the PlumX Metrics API. Twitter metrics data will also be removed from other Elsevier Solutions such as ScienceDirect, Digital Commons (including Digital Commons dashboards) and Pure.
