You're managing your first app campaign and understand that text is an important input, but you're not sure what to write for the headlines and descriptions. Which describes the guidance for writing effective headlines and descriptions for app campaigns?

In an App campaign, the most effective approach is for headlines to focus on highlighting the key features of the app and description lines to aim to educate and inform because this hierarchy quickly communicates the app’s primary value proposition to a scrolling user while providing the necessary context for them to understand its utility. Since these text assets are mixed and matched by machine learning to find the best-performing combinations, focusing on clear features in the headline ensures the core benefit is always visible, while the descriptions provide the deeper detail required to convert an interested prospect into a downloader.
