App Store ASO: the 7 things that actually move the needle
Most ASO advice is recycled from 2019. This guide covers what actually drives keyword ranking and conversion in 2026, based on data from 500,000 analyzed apps.
ASO is not keyword stuffing
App Store Optimization has a reputation problem. Most tutorials teach you to cram keywords everywhere and hope the algorithm rewards you. That approach is less effective every year as Apple gets better at understanding intent rather than literal keyword matching.
Real ASO in 2026 is about three things: signaling relevance clearly, converting visitors to installs efficiently, and maintaining rating velocity. Everything else is secondary.
1. Title keyword placement
Your app title carries the highest keyword weight of any metadata field. The primary keyword should be in the title, not buried in a subtitle or keyword field. Apple weights the first words more heavily, so "Somatic Exercise: Guided Movement" outperforms "Move Daily: Somatic Exercise App" for the keyword "somatic exercise."
Keep the title under 30 characters if possible. Longer titles get truncated in search results, which hurts click-through rate and wastes the characters you had.
2. Subtitle as a secondary keyword slot
The subtitle is indexed by Apple and appears in search results. Use it to capture a secondary keyword that complements the title without repeating it. If your title targets "somatic exercise," your subtitle might target "stress relief movement" or "nervous system reset."
The subtitle is also the first brand copy many users read. Make it descriptive rather than clever. Users who find you in search are in discovery mode. They want to understand what the app does in three seconds.
Never repeat words from your title in your subtitle. Apple does not give you credit for repetition, and you waste valuable indexed characters.
3. Screenshot conversion is the highest-leverage lever
Most developers treat screenshots as an afterthought. They are the single highest-leverage element for conversion. Users spend three to five seconds scanning screenshots before deciding to install or scroll past.
The first screenshot should communicate the core value proposition, not show the app UI. "Your calm. In 7 minutes." converts better than a screenshot of your home screen. Show the outcome, then show how the app delivers it.
Test your screenshots. Change one element, run a product page optimization experiment through App Store Connect, and measure conversion lift. A 15% improvement in conversion rate is worth more than a 50% improvement in keyword ranking.
4. Keyword field strategy
The 100-character keyword field is not indexed the same way as your title and subtitle. Use it for words you have not already used. Do not include the app name, common words like "app" or "free," or words already in your category.
Use commas without spaces to separate keywords. Apple treats each comma-separated term as a separate keyword unit. "tracker,journal,log" gives you three keywords; "tracker journal log" gives you one long phrase.
5. Rating velocity beats total rating count
An app with 500 ratings averaging 4.8 in the last 30 days will outrank an app with 50,000 lifetime ratings at 4.2. Apple cares about recency. Users who installed recently and rated highly signal that the app is still actively maintained and delivering value.
Build a rating prompt that appears at a moment of genuine success. Not after a user opens the app for the third time, but after they complete a workout, log a streak, or finish a task. Earned prompts convert at 3 to 5 times the rate of timed prompts.
6. Localization is free keyword real estate
Every localized App Store market (UK, Australia, Canada for English; DE, FR, JP, KR for other languages) has its own keyword index. Your US metadata does not help you rank in Japan. Your Japanese metadata does not affect your US rank.
If you are only in the US market, you are ignoring potentially larger opportunity in Japan or Germany. Many app categories are less saturated in non-English markets because fewer Western developers localize. A niche that scored 45 in the US might score 78 in Japan.
Use machine translation as a starting point for metadata localization, then have a native speaker review the title and subtitle specifically. The keyword field matters less for quality.
7. The first-week chart rank
Apple gives new apps a brief editorial boost in their category during the first 60 days after release. During this window, a burst of installs can push you into the top charts, which creates a compounding flywheel: chart visibility drives organic installs, which drives more installs.
Coordinate your launch with a Product Hunt post, a newsletter mention, or a Reddit thread in a relevant community. You do not need tens of thousands of installs. In a niche category, 200 installs on launch day can put you on the first page of top charts.
