The number of citations of a researcher does not necessarily correlate with the quality of their research or scholarly contribution. Here are some thoughts of Dr. Ziaul Haque Munim:
(!) Citations depend on the number of people working in the field/topic. You can be a great researcher in a niche topic/field, but if not many people are actively researching or publishing in that area, chances are your citations will not boom.
(!!) Research on contemporary topics always brings more citations. For example, studies related to Covid, blockchain, industry 4.0, big data and the like received huge citations in recent years.
(!!!) Citations depend on the availability of funding. One reason why research on contemporary topics receive more citations is that government and non-government agencies fund more research on contemporary topics.
(!V) Well crafted literature reviews get lots of citations. 03 out of the 05 of my most cited articles are literature reviews. Well, not all literature reviews get a lot of citations; even some say literature reviews are hard to publish. But well-written ones will get published and get cited.
(V) Simple sentence structure increases citations. A large number of readers in the scientific community are non-native English language speakers. Science is already hard, and we should not make it harder by using complex words and sentence structures. The more people can read your text easily, the more citations.
(V!) Your presence is likely to increase your citations. During my PhD, I realized that I was reading and citing articles written by people I already knew or connected on LinkedIn, and met at conferences.
