App store optimization (ASO): how small apps rank in App Store search

Why ASO is the channel that works without an audience or a budget

Building the app was the easy part. Your TikToks die under a few hundred views and a small Meta budget brings almost nothing. App Store search is different: people type what they want, and the store hands them a list. If your app is on that list, you get installs without an audience and without paying for each one. In the indie threads we read, ASO comes up in 30 of 90, and one developer called it "the most attainable" route, because it brings "free traffic from the app store".

Apple says plainly what it ranks on. Search results use text relevance, meaning matches for your app's title, subtitle, keywords and primary category, plus user behavior: downloads, ratings and reviews. So ASO has two halves. The text half you control today. The behavior half you build over weeks.

• App name: up to 30 characters, and the strongest place for your main phrase.
• Subtitle: up to 30 characters, shown under the name everywhere in the store.
• Keywords field: 100 characters, comma separated, no spaces after commas. Do not repeat words already in the name, subtitle or category, and skip plurals.
• Promotional text does not affect ranking, so keywords there are wasted.

Copy this first: put the search phrase in the app name

Look at the full App Store names of the apps in our data that grow mostly from search. Almost none of them is just a brand. The name says what people type.

• Chatbot AI Assistant - Genie. An outside analyst pointed out that the maker keeps "the keyword first (Chatbot AI Assistant) and brand (Genie) after it". It has 203,153 US ratings and charts in 23 of the 25 countries we track.
• Home AI - AI Interior Design. It ranks first for "ai interior design" in the US, Brazil and Mexico, and stood at US free 2 and US grossing 3 in our chart snapshot.
• AI Cleaner: Clean Up Storage. An outside commentator credits it with ranking top 3 for 350+ keywords, including "ai cleaner" and "free storage cleaner". That is the commentator's count, not ours.
• Scan QR Code Now. The name is the search. No creator or social channel is visible, and it still reached US grossing 22 with 13,390 US ratings.
• Simply Draw: Learn to Draw. It ranks first for "drawing lessons", with Meta ads on top.

The pattern: brand short, phrase after a colon or dash, and the phrase is a plain description a stranger would type. If your app is called a made-up word and nothing else, the store has no idea what to match it to.

Win a small phrase before a big one

A new app with few ratings will not rank for "photo editor" or "ai chat". It can rank for a narrow phrase that bigger apps ignore. Boothie is the clearest example we have of a single developer doing this.

Boothie launched on 2026-06-23, built around the digicam flash look. Within weeks it ranked on "digicam flash" and "ai filters" and charted at free 34 and grossing 37 in Turkey, with no ads found in the Meta or TikTok ad libraries. It did this with tiny numbers: 353 ratings across all 25 stores we track, 239 of them in Turkey, which is 67.7% of the total. A small phrase in one country was enough to reach a chart.

The other side of this is a generic name in a crowded search. The app called Authenticator shares that name with at least 45 apps. In our search check it ranks 5 for "authenticator app" in the US and only 4 for its own name. When your name is the category, you never own your own search.

Translate the listing for every country you want

Every country's App Store is its own search. A listing only in English competes badly in Germany or Brazil. Apple's own advice is to localize the product page so people in other regions understand the app and are more likely to download it. Our locale tracker shows what that looks like in practice.

• Authenticator has its listing in the main language in 25 of the 25 stores we track, and charts in 22 of them.
• Authenticator App, a newer rival launched 2025-11-19, covers 24 of 25 and lists in 34 store languages. It charts in 23 of 25.
• ChatOn covers 22 of 25 and charts in all 25. Brazil is its second market, with 11.3% of its ratings.
• Scan QR Code Now covers 4 of 25. It charts in 15 countries, but 89% of its ratings come from the US.

We cannot prove the translations caused the charts, since these apps also differ in other ways. But the search-led apps that spread across many countries are the ones with translated listings. Translating the name, subtitle and keywords into a few languages costs very little next to any ad budget.

Ratings: the half of the ranking you build over weeks

Apple says ratings and reviews appear in search results and can influence how your app ranks. Getting the first few is the hard part, as one indie developer put it, and you only get a few chances: Apple lets you show its rating prompt up to three times in a 365-day period.

So show it at a good moment, right after the user gets the result your app promises, not on first launch. The search-led apps in our data show steady review flow rather than spikes. Scan QR Code Now went from 20 reviews read in May 2025 to 71 in December 2025, then held at 27 to 61 a month. Simply Draw rose from 2 to 12 a month in late 2024 and has stayed at 10 to 39 a month since. Bluey, at the large end, holds rank 1 for its brand and rank 2 for "kids" in the US and Mexico.

Screenshots turn a search into an install, Search Ads speed it up

Ranking gets you onto the list. The screenshots decide the tap. When there is no app preview video, the first one to three screenshots appear in the search results themselves, so they have to show the result in one look. You can add up to 10, and up to three previews of up to 30 seconds, which autoplay muted on the product page. Treat screenshot one like the first second of a TikTok: show the after, not your menu.

Search is also where paid and free meet. AI Cleaner is described by the same outside commentator as an ad funnel "backed by smart ASO": its Meta ads run at high volume next to a listing tuned for "ai cleaner" terms. Cal AI's founder told other developers not to sleep on Apple Search Ads, citing $200 of free credits and the most accurate attribution. Simply Draw's parent company was once showcased by Apple for its Search Ads results. If you have a small budget, spending it on the exact phrases you are trying to rank for is the cheapest test of which phrase converts.

What to do this week

• Search the App Store for the three apps closest to yours. Write down their full names and subtitles. Those are the phrases they bet on.
• Pick one narrow phrase you can win, like Boothie's "digicam flash", and put it in your app name after your brand.
• Use the subtitle for a second phrase and the 100 keyword characters for related words, with no repeats and no plurals.
• Translate the name, subtitle and keywords for your two or three biggest non-English markets.
• Redo screenshot one so it shows the result your app gives, readable at search-result size.
• Move the rating prompt to the moment after the first success, not the first launch.
• Check your rank for the phrase each week. Change one field at a time so you know what moved it.

ASO is slow and it compounds. It works best alongside one channel that brings bursts of downloads, because Apple counts downloads too. For that side, see how the same kind of apps use creators and ads.

Questions

What is app store optimization?

App store optimization, or ASO, is the work of getting your app shown and tapped in App Store and Google Play search. On the App Store that means your name, subtitle, keywords, category, screenshots and ratings, since Apple ranks on text matches plus downloads and ratings.

How do I do app store optimization for a new app?

Start with one narrow phrase you can win and put it in the app name after your brand, as Boothie did with "digicam flash". Fill the 30-character subtitle and the 100 keyword characters with related words, translate them for your main markets, and ask for ratings after the first success.

What is the App Store keywords character limit?

The keywords field holds 100 characters, separated by commas with no spaces. The app name and subtitle hold up to 30 characters each. Do not repeat words that are already in the name, subtitle or category, and do not add plurals of words you already have.

Does ASO still work in 2026?

Yes, for apps that pick phrases they can win. In our data, Scan QR Code Now, Authenticator and Genie grow mostly from search with no visible creator channel, and Boothie reached a Turkish chart with 353 ratings in total.

What does Reddit say about app store optimization?

In the indie threads we read, ASO comes up in 30 of 90. Developers call it the most attainable route for small apps and say the first reviews are the hardest part. Our data agrees on both: small phrases win first, and ratings are half of what Apple ranks on.

Do I need ASO tools?

Not to start. Searching the App Store yourself shows which phrases your competitors put in their names and subtitles, and Apple Search Ads shows which phrases convert. Tools help once you track many keywords across many countries.
