Introduction

App Store Optimization (ASO) is the process of improving the visibility and discoverability of a mobile application in app stores like the Apple App Store and the Google Play Store. Similar to Search Engine Optimization (SEO), ASO aims to increase organic downloads by enhancing various elements of the app listing to rank higher in search results and top charts.

This glossary entry provides a comprehensive look at ASO from an information technology perspective, covering its components, tools, techniques, and best practices to empower IT teams, app developers, product managers, and digital marketers.

What is App Store Optimization (ASO)?

App Store Optimization (ASO) refers to the strategic process of optimizing a mobile app’s metadata (like title, keywords, description) and other assets (icons, screenshots, videos) to improve its ranking in app store search results. ASO aims to boost visibility, attract more users, and increase conversion rates.

In the mobile-driven world, apps serve as a major platform for user engagement. From an IT and development perspective, investing in ASO ensures that the time and effort spent on app development pay off with increased visibility and ROI. ASO enables companies to:

  • Acquire high-quality users
  • Improve organic traffic
  • Lower user acquisition costs
  • Strengthen app branding

Key Elements of ASO
