There are several factors that have to be considered in studying the celebrity endorsement. These include the type of campaign, the stage of the product in the life cycle and the region. The products that are well established or at the start of the product life cycle are benefitted the most by the involvement of the celebrity in the advertisement campaign. The gluten free diet isn’t an old campaign and thus celebrity has to be involved so as to increase the awareness and involvement (Hennessey, 2103). Further the campaigns that have an impact on the society are more successful if it is endorsed by the celebrity rather than the products that are for the financial benefit of the brand. This has been the case with gluten free diet and thus the association of celebrity has been quite beneficial. Lastly the level to which the celebrities are involved in the campaigns depend on the region in which it s being employed. According to Kim (2011), the extent to which the celebrities are involved in the ad campaigns in Canada is very less in comparison to Korea. In Canada the focus is more on communicating the information to the prospective customers rather than glamorizing the campaign by involving actress. This is because of the cultural differences that exist between Canada and Korea (McDonald & Zima, 2006). This is the reason why the celebrity involvement has been quite limited.
