App Store Optimization (ASO) Basics: Get Found and Downloaded
App Store Optimization (ASO) is the process of improving your app's visibility in app store search results. With over 70% of users discovering apps through search, mastering ASO is essential for sustainable growth.
The ASO Fundamentals
ASO can be broken down into two main areas: on-metadata factors (elements you directly control) and off-metadata factors (user behavior signals).
On-Metadata Factors
App Name/Title
Your app name is the most important ranking factor. Include your brand name plus primary keywords. App Store allows 30 characters; Google Play allows 50.
Example: "Headspace: Meditation & Sleep" includes brand name and two key search terms.
Subtitle (iOS) / Short Description (Android)
Use this space for secondary keywords and value proposition. Keep it compelling — this text appears in search results.
Keywords (iOS Only)
Apple gives you 100 characters for keywords. Use commas to separate terms, don't repeat words, and skip spaces to maximize character usage.
Description
On iOS, the description isn't indexed for search but helps conversion. On Android, it's indexed — include relevant keywords naturally. Front-load important information in the first 2-3 lines visible without "Read More."
Screenshots & Video
Visual assets dramatically impact conversion rates. Best practices:
- Lead with your most compelling feature
- Add text overlays explaining benefits
- Show the app in action, not just static screens
- Include a preview video (auto-plays in search)
Off-Metadata Factors
- Download velocity: More downloads = higher rankings
- Ratings and reviews: Quality and quantity both matter
- Retention and engagement: Apps users keep using rank higher
- Update frequency: Regular updates signal active development
Keyword Research Process
- Brainstorm initial keywords based on your app's features
- Analyze competitor keywords using ASO tools
- Check search volume and difficulty scores
- Target a mix of high-volume and long-tail keywords
- Track rankings and iterate monthly
ASO Tools
Consider using tools like App Annie, Sensor Tower, or AppTweak for keyword research and competitor analysis. Most offer free tiers suitable for indie developers.

Frequently Asked Questions
What is App Store Optimization (ASO)?
App Store Optimization is the process of improving your app's visibility in app store search results and increasing conversion from page views to downloads. It covers on-metadata factors you control (title, subtitle, keywords, description, screenshots, video) and off-metadata signals (download velocity, ratings, retention, update frequency).
How do I improve my app ranking in the App Store?
Focus on these key areas: include primary keywords in your app title (30 chars on iOS, 50 on Android), write a compelling subtitle with secondary keywords, use all 100 keyword characters on iOS, lead screenshots with your best feature and add text overlays, include a preview video, actively request reviews from satisfied users, and update regularly to signal active development.
