What is ASO, and what does an ASO tool do?
App Store optimization (ASO) is how you get your app found in App Store search: choosing the keywords people use and putting them in the places Apple reads. An ASO tool shows you which keywords are worth it.
What is App Store optimization?
When someone types a search into the App Store, Apple decides which apps to show and in what order. ASO is the work of making your app one of them, for the searches that matter to you. It covers your keywords and metadata first, and also your screenshots, ratings and reviews, which decide whether people download once they see you.
How App Store search picks apps
Apple doesn't publish its ranking formula, but these are the parts you control that matter most:
- App name (title), up to 30 characters. The strongest place for your most important keyword.
- Subtitle, up to 30 characters, shown under your name.
- Keyword field, up to 100 characters, hidden from users. Separate keywords with commas and don't repeat words already in your title or subtitle.
- Ratings, reviews and downloads, which tell Apple people want your app.
What an ASO tool does
An ASO tool replaces guesswork with data. The core jobs are:
- Keyword research: find the keywords people search for, and related ones you hadn't thought of.
- Keyword difficulty: see how hard it is to reach the top 10, judged from the apps ranking there now.
- Competitor analysis: find the keywords your competitors rank for and you don't.
- Rank tracking: watch your positions change after each update.
- Metadata help: fit your best keywords into the title, subtitle and keyword field without wasting characters.
Kivho does all five in one place, built for indie developers and small studios.
How to choose an ASO tool
- Does it explain keyword difficulty, or only show a number?
- Does it suggest keyword ideas beyond the words you already use?
- Can you compare your app with competitors?
- Does it help you write the metadata, not just research it?
- Does the price fit the number of apps you run? Many ASO tools are priced for large teams.
A quick ASO checklist for your next update
- Pick one main keyword you can realistically rank for and put it in your title.
- Use the subtitle for a second keyword and a clear benefit.
- Fill the keyword field with single words, separated by commas, with no spaces and no repeats.
- Ship the update, then track your rankings for two to three weeks before changing again.
Frequently asked questions
- What are ASO tools?
- ASO tools are software that help you improve how your app ranks in app store search. They show which keywords people search for, how competitive each keyword is, which apps rank for it, and how to use your metadata to target the right ones.
- Is ASO worth it for indie developers?
- Yes. Most App Store downloads start with a search, and choosing the right keywords costs nothing but time. For a small app, ranking for a few specific keywords is often more realistic and more valuable than chasing broad, crowded ones.
- How long does ASO take to work?
- Keyword changes go live with an app update. Rankings usually take from a few days to a few weeks to settle, so change one thing at a time and give each change time before judging it.
- What's the difference between ASO and SEO?
- SEO is about ranking web pages in search engines like Google. ASO is about ranking apps in app store search. The ideas are similar, but app stores use your app's title, subtitle, keyword field, ratings and downloads instead of web pages and links.
