Megan is setting up a Google App campaign but she's not sure how specific to be when it comes to location targeting. Why should a marketer set a location target that's at country level or larger?

Setting a location target at the country level or larger is advantageous primarily because the system functions optimally when it has access to a vast dataset. By setting a broader location target, such as at the country level, marketers ensure that the campaign leverages a larger pool of user data, enabling machine learning algorithms to identify trends, patterns, and user behaviors more effectively. With a larger dataset, the system can make better-informed decisions regarding ad placements, audience targeting, and bidding strategies, ultimately optimizing campaign performance and maximizing reach. Moreover, targeting at a country level or larger simplifies campaign management and reduces complexity, as it eliminates the need to manage multiple smaller targeting regions separately. This approach aligns with the scalability and efficiency that are inherent to machine-learning-powered campaigns, allowing marketers like Megan to streamline their efforts while achieving optimal results.
