<p>Earth sciences have mainly evolved from the observation, description, and interpretation of elements of geodiversity. One of the most recent themes within this context is geotourism, which has been gaining ground in scientific research. This work presents a systematic study of criteria for evaluating geological sites with a focus on tourism. The objective is to develop a comprehensive literature review on quantitative assessment criteria for the tourist potential of geological sites, using bibliometric research as a key statistical tool for managing information and scientific knowledge. The literature search yielded 556 articles from the Scopus Preview and Google Scholar platforms, and after screening for relevant findings, 153 articles from 2013 to 2023 were selected. The final selection included only those articles that proposed methods with criteria for assessing tourism value, identifying 13 distinct quantification methods. The results reveal that there has been significant growth in research on the topic. Geographical analysis points to a higher percentage of contributions from European countries. Overall, a large portion of research focuses on the description and evaluation of the geotourism potential of specific areas. Other objectives include management and planning, proposal of geoparks, and comparison between evaluation methods. Few studies propose evaluation methods. This review identifies that there is no single method for evaluating geotouristic sites, and there is a need to complement or adapt existing methods. Evaluation methods are the only means to assess these values; however, they are subjective, and the results of the analyses depend largely on the knowledge and experience of the evaluator. The studies need to be strengthened, including the definition of criteria that best assess and provide the necessary knowledge for the successful development and management of geotourism under the sphere of geoconservation.</p>
