App Store Optimization (ASO) for Indie Developers
ASO is what determines whether your app gets found on Google Play and the Apple App Store — or buried. Here's everything you need to know, and how PostBuild AI automates the entire process.
Generate Your ASO Store Listing FreeWhat is App Store Optimization (ASO)?
App Store Optimization (ASO)is the process of improving your app’s visibility and conversion rate in the Google Play Store and Apple App Store. Think of it as SEO — but for mobile app stores.
Over 65% of app downloads start from a store search. Without proper ASO, users searching for apps like yours will find your competitors instead. Good ASO means your app surfaces for the right keywords and converts visitors to installs.
ASO covers two areas: keyword optimization (getting found) and conversion rate optimization (turning store page views into installs). Both matter, and both are covered by PostBuild AI.
The 4 Core ASO Ranking Factors
Keyword Optimization
Place high-volume, relevant keywords in your title, subtitle, and description. Title keywords get 3× the weight of description keywords.
Conversion Rate
Screenshots are the #1 driver of install conversion. Compelling captions and on-brand visuals can double your CVR from store page visit to install.
Ratings & Reviews
Apps with higher ratings rank higher. Prompt satisfied users to rate your app. Respond to negative reviews — stores factor this in.
Localization
Localizing your store listing for major markets can increase organic downloads by 50–200%. Start with English, Spanish, and German.
Google Play vs Apple App Store: ASO Differences
Each store has its own algorithm and metadata fields. Optimizing for both requires understanding the differences.
Google Play
Most important ranking signal. Front-load your primary keyword.
Appears in search results. Use your second strongest keyword.
Fully indexed by Google. Repeat keywords naturally 3–5 times.
Apple App Store
Include your primary keyword. Most heavily weighted ranking factor.
Second strongest ranking signal. Target a different keyword than the name.
Comma-separated keywords NOT in your title/subtitle. Never repeat words.

ASO FAQ
What is App Store Optimization (ASO)?
App Store Optimization (ASO) is the process of improving an app's visibility and conversion rate in the Google Play Store or Apple App Store. It involves optimizing your app title, subtitle, description, keywords, screenshots, and icon to rank higher in search results and convert more visitors to installs.
What is the difference between ASO for Google Play and Apple App Store?
Google Play uses the title (50 chars), short description (80 chars), and long description (4000 chars) for keyword indexing. Apple App Store uses the app name (30 chars), subtitle (30 chars), and keyword field (100 chars) for search indexing — the description is NOT indexed. Both stores weight title keywords most heavily.
