How to measure and increase your research impact: Measuring your Impact

This libguide is to know how to increase your impact and how to measure your research impact

Author Impact

Author's impact is based on articles and papers published by this author and citations to these articles and papers.


Is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. It is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. Tools for calculating the H-index can be measured in Web of Science, Scopus and Google Scholar.


Is an index for quantifying productivity in science, based on publication record (an author-level metric). It is calculated based on the distribution of citations received by a given researcher's publications, such that given a set of articles ranked in decreasing order of the number of citations that they received.


The number of publications with at least 10 citations. This very simple measure is only used by Google scholar which is an disadvantage compared to other impact measuring tools, and is another way to help measure the productivity of a scholar.


The m-quotient aims at weighing the period of academic Endeavour so that even junior scientists attain the importance that they deserve. Thus, if n=number of years since the first published paper of the scientist, the m-quotient=h-index/n. However, the m-quotient may not stabilize until later in the scientist's career. for researchers in the early part of their career, who have low h indices, small changes in the h-index can lead to large changes in the m-quotient. Hirsch suggests the researcher's first published paper may not always be the appropriate starting point, especially if it was a minor contribution that was published well before the academic's period of sustained productivity. Although the m-quotient adds time as a weighting factor, it does not cater to the major disadvantages of the h-index including quality of publication and quality of citation.

Article Impact

Article impact factor is a measure of the frequency in which the average article in a journal is cited in a particular year. Impact factors measure the impact of a journal, not the impact of individual articles.

Article level metrics are an evolving area.  Measures include the number of citations in social media sites, as well as open peer or crowd-based recommendations or reviews.  

Altmetrics is the term used to denote the social media based article level metrics.

Altmetrics for Social Impact

Altmetrics is a new method of measuring impact, which looks beyond journal citations. It also captures mentions in social media, blogs, bookmarks, news media, in policy documents, and the number of downloads. Altmetrics are available faster in comparison to citation counts which take a longer time to accrue.

Journal Impact

Impact Factors are used to measure the importance of a journal by calculating the number of times selected articles are cited within the last few years. The higher the impact factor, the more highly ranked the journal. ... The Journal Citation Reports (JCR) database tracks all impact factors for 12,061 journals.

To find the impact factor of a journal use all or one of the following:

Eigenfactor and article influence

Journal citation reports

SJR SCImago journal and country ranking
