The paper describes the creation of a simulation model of the activity of a content manager to increase the effectiveness of marketing, and also defines the relationship of content marketing with Internet marketing in general. Simulation modeling in the AnyLogic program was used as the main research method. The literature sources on the topic of content analysis were analyzed, the processes in the work of a content manager that are subject to automation were highlighted. A simulation model of automation of the content manager's activity in the AnyLogic program was also developed and the economic efficiency of the implemented measures was justified. The scientific novelty of the proposed method lies in the fact that the model takes into account the need to create reports on promotions, as well as the need to conduct SEO promotion and evaluate the effectiveness of advertising on different Internet platforms: yandex.direct and google.awards. The results of the research can be used by IT specialists to create and improve software products.
