An innovative idea developed by the researchers should reach the end user groups. The output of any researcher can be judged in terms of patents or his publications in the respective fields. Quality and impact of research work can be based on the citation and h index. Nowadays, there are several parameters considered for evaluating the performance of the research. Citation and h index are the quality parameters used for rating the originality and use of research. They are more useful for accessing the potentials of research as well as for providing a platform for collaborative projects at national / International levels. This paper presents the comparative analysis of citation and h index for identified researcher through three popular databases viz., Google Scholar, Scopus, and Publons. Among the three databases, Google Scholar showed a higher number of citations of the selected author due to data collected from unauthenticated documents as well as well established research databases.
