In an app campaign, Google allows for a maximum of 20 HTML, image, and video assets to be included per ad group. This limit helps ensure that advertisers can provide a diverse set of creative materials, which can significantly enhance the effectiveness of the campaign. By having the option to use a variety of assets, businesses can better tailor their advertisements to resonate with different audiences and contexts, ultimately improving performance.
The reasoning behind this asset limit also ties into Google’s machine learning capabilities, as it enables the system to test different combinations of assets to determine which are most effective. This facilitates a more dynamic approach to ad customization and optimization, enabling advertisers to adapt their strategies based on real-time data and insights.
The other specified numbers do not align with the established limits for app campaigns and therefore would not support the comprehensive variety and testing needed to optimize campaigns effectively.
