The h-index does not increase linearly with citations. It is the number n of publications that have at least n citations. In ResearchGate, your h-index is 19. To reach an h-index of 20, you will have to have 20 publications with at least 20 citations each. However, usually citations are not distributed equally over all publications, but concentrate on a few. - Note also that ResearchGate may not have found all citations. For more about this, see https://www.researchgate.net/post/Why_citation_score_for_author_publications_looks_different_on_Scopus_research_gate_google_scholar and the links to more discussions therein.

The h-index score generally only increases over time as a researcher's publications accumulate citations. It can also increase when a researcher publishes new, well-cited papers. However, the h-index is not static and can change as citations accumulate or if papers are retracted.

The H-index increases when:

• You publish new papers that get many citations.

• Existing papers receive enough new citations to meet a higher threshold.

For example, to go from an H-index of 10 to 11, you need 11 papers with at least 11 citations each.

It updates as citation databases track your work.
