Author metrics are used to track how often an author's work is cited, and demonstrate the reach and impact of a researcher's work, for use in grant applications, tenure, promotion and performance reviews. An author's impact is frequently quantified in terms of the number of citations to their publications. Master Author metrics terminology, then use Author metric terms and key measuring tools for authors and collaborators to measure your impact.
Author metrics are also used to discover key researchers in the field, track the work of colleagues and identify potential collaborators.
One of the biggest challenges to tracking and analysing an author's impact is having a correct, complete publication list for that author. Consider establishing your author profile linking all your publications to a persistent author identifier - see more information in Researcher Profiles & Networks
The author h-index was proposed by J.E. Hirsch in a 2005 article, which measures a researcher’s impact based on the number of citations to their work.
h-index = number of papers (h) with a citation number ≥ h.
Example: If an author has an h-Index of 9, it means that out of the total number of published documents by that author, 9 of those documents have been cited 9 times.
Keep in mind that the name you publish under may impact on your h-index; search for every variation of your name used in your publications.
Web of Science and Scopus are the main source databases for the author h-index.
Publish or Perish - merge this data with that from Web of Science and Scopus, then deduplicate results
Note: The h-index is not widely used outside the Sciences. At Otago, Humanities scholars are advised not to use the h-index, nor early-career academics. Citation counts do not necessarily reflect research impact in the Humanities. Social Science scholars may find the journal h-index useful when selecting where to publish.

Harzing's Publish and Perish Manual explains the g-index is calculated based on the distribution of citations received by a given researcher's publication.
For example: A g-index of 20 means that an academic has published at least 20 articles that combined have received at least 400 citations.
It was suggested in 2006 by Leo Egghe (See: Theory and practise of the g-index).
One of the main advantages of the g-Index is the inflated values of this index helps give credit to lesser cited or non-cited work whilst attributing credit for highly-cited papers.
The i10-Index, used solely by Google Scholar, was introduced in July 2011. It calculates the number of academic publications an author has written that have at least ten citations from others. This is one way to gauge the productivity of an author.
i10-Index = the number of publications with at least 10 citations.
Note: In order to use the i10-Index authors must have a public Google Scholar profile (See: Google Scholar Citations).

Scopus is a multidisciplinary database from Elsevier, referencing journal articles, books and chapters back to 1823. Citation information goes back to 1996, however, data from 1970 is being added.
Use Author Search to generate a Citation Overview and the Analyze author output page. This analyses the publishing output of an author or a group of matched authors using the h-index.
The h-graph displays the h-index for a single author, multiple authors, or a group of selected documents. The h-index is based on the highest number of papers included that have had at least the same number of citations.
Use Author Search and click Create Citation Report to view the h-index, and other analytics like the new Author Beamplot.
Researchers can use ResearcherID to manage author names/citations; see Researcher Profiles for more information.
Note: Publish or Perish version 7 is available as a native macOS application. You no longer need a virtual machine with Windows inside as you did for previous versions of Publish and Perish
Register for MyCitations to create an author profile, track your citations, and generate metrics.
Note: Unless you have a Google Scholar citation profile Google Scholar does not calculate your h-index (but you can use Publish or Perish).
