Research tools included library studies and in-depth, semi-structured interviews with experts. The triangulation method was used to ensure the accuracy and validity of the collected information. Holsti's coefficient of reliability for the research data was calculated to be 77 percent. The qualitative data analysis software Atlas-ti 2018 was used to extract and analyze the codes, categories, and dimensions of the research model from the interviews. Accordingly, at the end of the coding and data analysis stages, 135 codes, 19 categories, 5 dimensions, and 1 central phenomenon were identified. According to the research model, the effectiveness of Iranian sports product advertising campaigns is at the center, with "organizational factors," "content factors," "psychological factors," "environmental factors," and "evaluation factors" as influential factors. The results of this study can serve as a guide for sports advertising campaign designers to design and plan advertisements that have effectiveness criteria and also provide the necessary confidence to achieve the advertising goals intended by sports product brand owners.
