App Store Optimization (ASO)

App Store Optimization (ASO) is the process of optimizing mobile apps for better visibility and higher download numbers in app stores. Similar to SEO for websites, ASO aims to improve the organic discoverability of apps and increase conversion rates.

ASO includes optimizing various elements such as app titles, descriptions, keywords, screenshots, icons, and reviews to rank the app higher in app store search results.
