![]() ![]() Research on GT has also become more diverse in terms of themes, with finance, Covid-19 and other health-related topics being the new dominant areas of research. Overall, the results show that the research on Google Trends has grown considerably in recent years, particularly since the outbreak of the Covid-19 pandemic. In the paper, two types of analyses are carried out: 1) a citation-based analysis that focuses on the overall publication trends and the identification of the most prolific authors, documents, journals, and countries, and 2) a mapping of themes in GT research and how these have evolved. We extracted bibliometric data from the Scopus database which were then analyzed quantitatively using the Bibliometrix software package. In this study, we conducted a bibliometric study of the first 15 years of Google Trends research (2007–2022). Since its introduction in 2006, it has been widely used in research in a variety of academic fields. Google Trends is a free analytic tool for measuring and monitoring web search data. Our study will provide various insights for researchers who utilize Google Trends as well as researchers who rely on various other sources of Big Data in their efforts to compare research trends and identify new areas for research. This study also demonstrates that in recent years, there has been an expansion in analysis in linkage with other social Big Data sources, as researchers attempt to overcome the limitations of using only search information. In addition, this study shows that research using Google Trends has increased dramatically in the last decade, and in the process, the focus of research has shifted to forecasting changes, whereas in the past the focus had been on merely describing and diagnosing research trends, such as surveillance and monitoring. ![]() The study reveals that Google Trends is used to analyze various variables in a wide range of areas, including IT, communications, medicine, health, business and economics. We also identified the important nodes of the networks and reviewed the research directions of representative papers. To this end, we conducted a network analysis on 657 research papers that used Google Trends. Our purpose is to conduct a comprehensive and objective research into how the public use of Big Data from web searches has affected research, and furthermore, to discuss the implications of Google Trends in terms of Big Data utilization and application. This study seeks to analyze the trends in research studies in the past decade which have utilized Google Trends, a new source of big data, to examine how the scope of research has expanded. ![]()
