Impact Metrics

What are Altmetrics?

Altmetrics or alternative metrics measure the attention a resource generates on the web. These metrics complement traditional metrics.

What altmetrics count?

  • Usage: the number of views and downloads where the resource is stored
  • Mentions:  the number of mentions on social media (Twitter, specialised social media such as Researchgate, blog posts), policy documents, mainstream media,  Wikipedia articles, comments on peer review platforms such as Pubpeer or  Publons
  • Captures: the number of captures in bookmarking tools such as Diigo or reference management tools as Mendeley and Citeulike
  • Citations: in Google Scholar, Scopus, Web of science
  • Measure impact almost immediately: it is possible to monitor the online mentions of a work as soon as it is published
  • Cover more diverse research outputs and sources than traditional metrics
  • Broader non-academic audience:  it can show attention beyond the academic world, where people may use but not cite research
  • Metrics can be easily manipulated
  • Invisibility: If a publication is more accessible, it is more likely to be cited. Altmetrics benefit researchers who have a strong online profile and are active on social and other media
  • Popularity does not always equals quality of research
  • Lack of stability on data sources as some of them come and go (Ex : Connotea)
  • Standards remain at the stage of development. In 2016, the US National Information Standards Organization (NISO) published a document in an effort to standardise practices concerning these new metrics
  • Without the analysis of the context, altmetrics indicators can not measure the impact research but only the “attention gathered by a research publication”

Publisher websites

Some publishers such as Springer usually integrate Altmetrics data in their websites:

  • With a badge or summary visualisation
  • With metric reports that include download and page view information

  • Platform owned by the data science company Digital Science
  • Offers a subscription for an Almetric explorer. It enables an institution to track the attention that publications by an individual researcher or university/institute get in social media.

  • Data company, owned since 2017 by Elsevier
  • Offers several products such as PlumX metrics, which embeds the metrics about a publication directly into an institutional repository, or "Plum Prints" displaying article usage, mentions, citations and shares that are available through the Scopus database for items indexed in Scopus.

Altmetrics and How to Improve the Visibility of Your Research

Communicate about your work on academic social media platforms:

  • Academic for-profit social networking platforms
  • Share research papers
  • Follow other researchers
  • Metrics on your profile and papers (number of views of your publications or profile)
  • Possibility to link your Academia profile to your ORCID ID
Communicate about your research on non-academic social networks:

  • Free social networks
  • Share information about your research in real time
  • Metrics about citation counts and users demographic information
  • Identify trending topics by country with Twitter
Publish with open access journals or archive your work on subject repositories such as :

  • Open-access online preprint community which offers an SSRN Author homepage for authors with publications indexed in the SSRN eLibrary
  • Multidisciplinary repository
  • Create a profile and make your work visible
  • Interact with other researchers
  • Metrics (number of citations and downloads)
  • Possibility to link your SSRN profile to your ORCID ID

Keep in mind:

  • The number of views, downloads or mentions does not necessary reflect the usage and impact of your research. It is always important to analyse the context to know what is said about your work
  • Creating a researcher identifier such as ORCID is important  in order to make easier for other researchers to identify you and avoid homonyms
  • Before publicly posting your work, make sure you have the right to do so
  • Do not forget to always precise the source of your indicators, as different providers (Altmetric, Impactstory) track different sources
