Abstract
Faced with the increasing competition conditions around the world with the effect of globalization, companies use various strategies in order to survive in the market and compete with their competitors. One of these strategies is to include famous people in commercials that companies use to differentiate themselves from their competitors. In this context, this study, it is aimed to reveal whether the trust in the celebrities who play in the commercial has an effect on the corporate credibility, brand credibility, and advertising credibility. In addition, the effect of age and gender as moderator variables on the model established in the study is also examined. The population of the research consists of individuals aged 18 and over who watch the advertisements played by celebrities broadcast on television in different regions of Turkey. Among the individuals constituting the main mass, 421 people were reached by convenience sampling method, 3 people were excluded from the research because they did not meet the criteria for participation in the research, and 418 people were included in the research. In the research, the data obtained through the online questionnaire were analyzed with SPSS and SmartPLS package programs. As a result of the analysis, it has been found that trust in the celebrities who play in the commercial has a positive and significant effect on the corporate credibility, brand credibility, and advertising credibility. It can be said that as the level of trust of a consumer in the celebrities playing in the commercials increases, the level of corporate credibility, brand credibility, and advertising credibility will increase. In addition, it was determined in the study that age and gender did not have a moderator effect on the relationship of all hypotheses.
