Google App Campaigns (formerly known as Universal App Campaigns) are designed to simplify the ad creation process for mobile app promotion. Here are a few ways in which Google App Campaigns simplify the ad creation process:

1. Automated ad creation: With Google App Campaigns, you don’t need to create individual ads for each ad group or placement. Instead, Google uses machine learning to automatically create ads for you based on the ad assets and targeting options you provide. This saves you time and effort in creating and managing ads.
2. No need to choose placements: With Google App Campaigns, you don’t need to choose where your ads will appear. Google will automatically show your ads on the most relevant placements across its networks, including Google Search, Google Play, YouTube, and more.
3. Easy ad asset creation: Google App Campaigns provide guidelines and recommendations for creating ad assets such as images and videos, which makes it easier to create high-quality ad assets that will be effective in driving installs and in-app actions.

Overall, Google App Campaigns offer a streamlined and simplified ad creation process for mobile app promotion, making it easier for you to promote your app and drive more installs and in-app actions.
