Nilou es una nueva anunciante que busca establecer su primera campaña. ¿Cuál de los siguientes métodos sería el mejor para crear su primera campaña?

Manual creation is the best method for Nilou's first campaign because it allows her to learn the platform's interface and understand each setting and option in detail. This hands-on approach is crucial for new advertisers to grasp how campaigns are structured and optimized. Using bulk operations spreadsheets or the API is more suitable for experienced advertisers managing large-scale campaigns or requiring advanced automation, as these methods assume a deep understanding of the platform and its data structures. "None of the above" is incorrect because manual creation is a viable and recommended starting point.
