Measuring your research impact: i10-Index

This guide provides an introduction to the various metrics used to measure researcher and journal impact.


Created by Google Scholar and used in Google's My Citations feature. 

i10-Index = the number of publications with at least 10 citations.  

This very simple measure is only used by Google Scholar, and is another way to help gauge the productivity of a scholar.  

Advantages of i10-Index

  • Very simple and straightforward to calculate
  • My Citations in Google Scholar is free and easy to use

Disadvantages of i10-Index

  • Used only in Google Scholar

Here is a screenshot of a Google Scholar My Citations page for Charles Darwin (you can see the i10-Index highlighted in the small table):
