When you choose to publish with PLOS, your research makes an impact. Make your work accessible to all, without restrictions, and accelerate scientific discovery with options like preprints and published peer review that make your work more Open.

Assessment of Impact with Article-Level Metrics (ALMs)

ALMs are quantifiable measures that document the many ways in which both scientists and the general public engage with published research. Traditional metrics, which consider only citation count and journal name to assess impact, capture a narrow view of a work’s value and do so only after the accumulation of citations in academic literature.

Track your ALMs


Assess impact before academic citations accrue

Incorporate both academic and social metrics

Reflect changing influence of a work over time


ALMs track the reach, use and reuse of research outcomes – from articles and figures to datasets and code – to help guide understanding of a work’s influence

Communicate Your Impact

Feature ALMs on your public profile pages (lab website, personal blog, ResearchGate,, LinkedIn) to tell your article’s story to those who are interested in your work.

Let Your Funders Know

The ability to demonstrate that your research generates significant interest could help secure the advantage you need in a tight, competitive funding environment.

Raise Your Career Profile

Showcase the influence of your work when you apply for tenure and promotion or when you apply for positions outside academia—in policy, industry or elsewhere.

Discover Research That Matters

ALMs can guide you to the most important and influential work, whether for analyzing trends in a field of interest, staying abreast of recent discoveries or searching ideas for a new project.

Connect with Collaborators

Identify potential collaborators early, based upon the impact of their work and its relevance to yours. ALMs allow you to find them while they’re actively engaged in the research of interest.


Because ALMs are available shortly after publication and are continually updated, they provide a snapshot of an article’s reach at any given moment. 

PLOS ALMs are calculated based on the following sources*:

*Totals may vary depending on the source’s methodology.

PLOS Journals (HTML, PDF, XML), PubMed Central (HTML, PDF)

CrossRef, Datacite, Europe PMC, PubMed Central, Scopus, Web of Science

F1000 Prime

PLOS Comments, Facebook, Reddit, Twitter, Wikipedia

CiteULike, Mendeley

For privately funded researchers, ALMs “show supporters of our research program the impact that is made by their contributions” and are an “intuitive way for non-scientists to understand the relevance and interest of seemingly esoteric research.
