[ Guide ]
App store optimization works on two things. The first is ranking: when someone searches the App Store or Google Play, the store decides which apps to show and in what order. It weighs how relevant your listing is to the search, and how people respond to your app: downloads, ratings and reviews.
The second is conversion: of the people who see your app in the results or on its page, how many install it. Your icon, screenshots, preview video, rating and the first lines of your description do that work.
The two feed each other. A better listing converts more of the people who see it, and more installs from a search help your app hold its place for it. That’s why app store optimization is ongoing work rather than a one-off task, and why an ASO tool tracks your results over time, market by market.
App metadata is the text of your store listing, the part of app store optimization you write yourself, and each store has its own fields and limits.
On the App Store: the app name (up to 30 characters), the subtitle (up to 30), a keyword field that users never see (up to 100 characters, words separated by commas), the promotional text (up to 170) and the description (up to 4,000). Apple’s search reads mainly the name, the subtitle and the keyword field, so every character there counts.
On Google Play: the title (up to 30 characters), the short description (up to 80) and the full description (up to 4,000). There is no keyword field: Google Play reads your descriptions, so the words you use there, and how naturally you use them, matter more.
Each language can have its own app metadata, which is where localization pays off: a listing written for each market, not just translated.
A good ASO tool turns your store data into decisions. Which keywords are worth targeting? Which words belong in your title? Which markets need attention? Some ASO tools stop at the data; others, like ASO Agent, also help you write the app metadata that acts on it.
Start with the data app store optimization runs on. An ASO tool should show each keyword’s search volume, its difficulty and your rank, country by country, how those ranks change over weeks and months, and the apps you compete with for them.
Then look at what it covers beyond keywords: your ratings and reviews and what people say in them, your screenshots and in-app events next to your competitors’, and your listing as each store shows it.
Finally, ask what the ASO tool does with all of that. Does it work for both stores? Does it handle every language you publish in? Does it keep a history of your changes? And does it help you write your listing, or leave the writing to you?
Both are about being found through search, and both start with the words people use. SEO (search engine optimization) works on websites and web search results; app store optimization works on your store listing and the store’s own search.
The rules differ. A web page can be as long as it needs; app metadata has strict character limits, so each word has to earn its place. Web rankings rely heavily on links from other sites; store rankings lean on your listing’s text, your downloads and your ratings. And ASO includes conversion on the listing itself: the screenshots and the rating that make people install.
They also meet. Your store listing can appear in web search, and AI assistants can quote it when someone asks for an app, so what it says travels beyond the store.
Most ASO tools show you the data and leave the writing to you. ASO Agent is an ASO tool that does both: keyword research, ratings and reviews and store preview, plus ASO Generation, which drafts your app metadata.
ASO Generation chooses its words from your keywords’ relevance, search trends, your own history and the competition. It writes the title, subtitle and keywords together, so they fit each other, plus the description if you pick it. Every change is marked against your live listing; you compare the versions and approve the one you want, or export it as XLSX.
As an ASO tool, it covers the App Store and Google Play in one place, and every language you publish in: an ASO Group drafts many locales in one run from a reference language, each saved in its own history.
[ FAQ ]
An ASO tool is software for app store optimization. It shows how your app does in the app stores: the keywords you rank for, your ratings and reviews, and your listing in each market. ASO Agent is an ASO tool that also writes your app metadata: ASO Generation drafts your title, subtitle, keywords and description in the languages you pick, for you to review and approve.
App store optimization (ASO) is the work of helping your app get found and chosen in the app stores. It covers your app metadata, your screenshots, and your ratings and reviews, market by market. It’s also called app store SEO, or Google Play SEO on Google Play. An ASO tool brings all of that work into one place.
The App Store and Google Play, in one ASO tool. You switch between your iOS and Android listings in the same app.
App metadata is the text of your store listing. On the App Store: the title, the subtitle, a hidden keyword field of up to 100 characters and the description; on Google Play: the title and the short and full descriptions. Each store matches searches against these words (the App Store mainly against the title, subtitle and keywords), so your app metadata shapes which searches your app can show up for, and AI answers can quote it too.
