What is App Store Optimization?
App Store Optimization (ASO) is the process of improving an app’s visibility, ranking, and conversion rate inside mobile app stores — Apple App Store and Google Play — through targeted metadata, keywords, screenshots, and store listing copy. Where SEO targets web search engines, ASO targets app store search and the algorithms that power category charts, recommendations, and Today/Featured placements.
A complete ASO workflow updates four levers in parallel: the keyword field and metadata that determine which searches surface the app, the title and subtitle that decide whether a user taps, the screenshots and preview video that drive install conversion, and the long description that supports retention and reviews.
- iOS keyword field
- 100 characters total. Comma-separated, no spaces between terms. Apple already indexes the title, subtitle, and developer name — never repeat those terms here.
- Title length
- 30 characters maximum on iOS. Lead with the brand, then the strongest keyword phrase. Truncation in search results is unforgiving.
- Subtitle length
- 30 characters on iOS. Use it for the second-strongest keyword phrase or a benefit clause that titles can't carry.
- Conversion rate benchmark
- Across AppGrowKit's analysis of customer App Store listings, 5–8% page-view to install is typical for productivity apps and top-quartile games hit 30%+. Screenshots one through three drive roughly 80% of the lift.
- Screenshot impact
- The first three screenshots are the only ones most users see in App Store search results. Treat them as the listing's above-the-fold.
- Localization lift
- Listings localized into the 12 top App Store languages typically grow installs 26–47% in those markets versus English-only listings.
Why it matters
ASO should not live in a spreadsheet away from your creative.
