The article shows that in the analysis of the labor market statistical and administrative data are used as an empirical base, which is insufficient for understanding current trends on it and making decisions. The authors determined the scope and features of the presentation of information about the labor market on online job portals, revealed differences in the formation and structuring of information, substantiated the need to use the data of online job portals in the Republic of Belarus to obtain a comprehensive picture of the labor market, since they cover different segments of the Belarusian labor market. Online job portals in the Republic of Belarus were evaluated and ranked. The authors formulated the difficulties of forming a single portal of vacancies for labor market analysts: - different criteria for structuring information in the description of vacancies and resumes, the use of different classifiers; - lack of unification in the use of methodological and methodological approaches (understanding the labor market situation, division into types of economic activities, categories of vacancies and resumes); - weak structuring and arbitrariness in the description of the required skills; - closed information. The directions of formation of the digital ecosystem of the labor market in the country are determined, including the collection and processing of information about the labor market from different sources, their relationship and integration with the education system, business entities, management bodies, ensuring the unity of methodological approaches in the formation of information (terminology, taxonomy, classifiers, etc.) and its provision to all interested users (management bodies for the development of programs and forecasts, personnel services of organizations, educational institutions, the population - employed, unemployed, who want to change jobs, find additional work, students, applicants, etc.).
