As of March 2017, there are over 2.8 million apps in Google Play and 2.2 million apps in the Apple App Store, making it increasingly difficult for new apps to stand out. To overcome this challenge, app store optimization (ASO) is crucial, which involves multiple strategies aimed at increasing discovery, downloads, and ranking. Optimizing keywords, designing an attractive icon, optimizing titles and subtitles, writing compelling descriptions, showcasing key features through screenshots, and localizing the app for global markets are all essential steps in ASO. Regular updates and improvements to the app also help build a relationship with users, keep the app on their minds, and increase revenue. With continuous refinement and analysis of outputs, ASO can lead to increased downloads, ranking, and ultimately, revenue.
