What are the four types of ad assets available in Google App campaigns?

The four primary ad asset types for Google App campaigns are HTML5, Image, Video, and Text. These assets allow advertisers to create diverse and engaging ads that can run across Google's extensive network, including Search, Google Play, YouTube, and the Display Network. HTML5 assets provide interactive and dynamic ad experiences. Image assets offer static visual appeal. Video assets are highly effective for demonstrating app features and engaging users through motion. Text assets are fundamental for conveying key messages and calls to action. HTML4 is an outdated standard and not a current asset type. Audio assets are not a standard, standalone asset type for App campaigns; while videos may contain audio, audio-only ads are not a core asset.
