App Store Optimization (ASO) is the process of optimizing your app to improve its visibility and ranking on app stores such as the Google Play Store and the Apple App Store. There are several factors that can impact your app’s visibility and ranking, including:

1. Keywords: Using relevant and popular keywords in your app’s title, description, and metadata can help it rank higher in search results.
2. Visuals: Using high-quality and visually appealing graphics, such as icons and screenshots, can help your app stand out and attract more downloads.
3. Ratings and reviews: Having a high average rating and a large number of positive reviews can improve your app’s ranking and visibility.
4. User engagement: Apps that have high levels of user engagement, such as those with a high retention rate and low uninstall rate, tend to rank higher in app stores.
