Nilou is a new advertiser looking to set up her first campaign. Which of the following methods would be the best for her to consider to create her first campaign?

Manual creation is the best method for a new advertiser like Nilou to set up her first campaign because it provides a guided, step-by-step interface within the advertising platform. This allows her to learn the campaign structure, targeting options, and ad creative requirements interactively. Bulksheets are designed for experienced advertisers managing large campaigns or making mass changes, requiring a deep understanding of campaign parameters and data formatting. Using an API (Application Programming Interface) is even more advanced, typically for developers integrating advertising functionalities into their own systems, which is far beyond the scope of a first-time advertiser. Therefore, manual creation offers the most accessible and educational approach for beginners.
