Research Impact

Welcome to the research impact guide

This guide introduces some key tools for informing research impact. You may use these tools for finding bibliometrics, journal rankings, analysing citations and Altmetrics.

The societal and economic impacts of your research activities are significant in your research journey. You may also like to read the following articles discussed the various ways to measure research impact:


Bibliometrics are indicators/metrics that analyse publications based on citation counts.

Use of Bibliometric tools

  • Metrics, such as citation counts and h-index, may help identify the impact of a researcher or a research output
  • Metrics may indicate research trends
  • Rankings and metrics may be used to inform decisions about journals to which you might submit your work for publication
  • Metrics may also help researchers decide which publication include in PBRF
  • Identify authors you might want to cite or collaborate with

Bibliometrics should always be interpreted cautiously. They are intended as a relative measure within a discipline, not as a numeric value to be taken in isolation.

Metrics toolkit

The new Metrics Toolkit may give you some ideas about the metrics available for researchers. Noted that this website doesn't cover these metrics: CiteScore (Scopus), SJR, SNIP, Snowball metrics, Eigenfactor, etc.
