Learn what App Store Optimization (ASO) is, how it works in the App Store and Google Play, and proven tips to boost visibility and downloads.
Here’s the reality: if your app doesn’t appear in those top search results, it might as well be invisible. Most users never make it past the first few options.
Think about it: around 65% of all App Store downloads start with someone typing a search. That means one thing: showing up for the right words isn’t just helpful— it’s everything.

It doesn’t matter how groundbreaking your app is. If people can’t find it, it won’t succeed. That’s why ASO isn’t a “nice-to-have” anymore—it’s your foundation. It’s what you do first, not last.

This isn’t about gaming the system. It’s about building something that gets found, chosen, and kept—day after day.
What is app store optimization?
App store optimization, usually shortened to ASO, is the process of making your app easier to find in stores—and more appealing once people land on your page. At its simplest, ASO does two jobs.

First, it helps your app show up when people search for something relevant. Second, it makes sure your store page looks good enough that people actually want to download once they find you.
Think of it as the app world’s version of SEO. Just like websites compete to show up on Google, apps compete to show up in store searches.

If your app doesn’t appear when people type in relevant keywords, you’re invisible to a huge portion of your potential audience. And even if you do show up, your store page has to work hard to convince people to download instead of scrolling past.

ASO pays off in a few simple but important ways:

  • Visibility. The higher you rank for the right keywords, the more people see your app before they see your competitors.

  • Relevant users. ASO puts your app in front of people actively searching for what you offer, which means better engagement and retention.

  • Cost efficiency. Organic installs lower your reliance on ads and keep acquisition costs under control.

  • Trust and credibility. Apps that rank at the top and carry strong ratings look more reliable, which makes users more likely to download.

Sustained growth. Ads stop the moment you stop paying. ASO keeps working as long as you maintain and update your app.
How ASO actually works
Forget complex explanations. ASO works because app stores want to make their users happy. They do this by trying to show the best possible app for every search.

Think of it like this: when you search for “photo editor,” the store’s job is to show you an app that edits photos, works well, and people actually enjoy using.

The stores figure this out by looking at:

  • Your words: do your title and description mention the things people search for?

  • Your reputation: do your ratings and reviews show people are happy?

  • Your staying power: do people keep using your app after downloading it?

  • Your looks: do your screenshots and icon make people want to tap “Install”?

  • Your activity: do you update regularly and keep your app fresh?

Here's the important part: Apple and Google do this differently.

Apple cares a lot about how you describe your app and what keywords you use, while Google is more interested in whether your app actually performs well on Android devices.

You already guessed: you can't use the same approach for both stores. What makes Apple happy might not impress Google, and vice versa.

Good ASO isn't about tricking the system—it's about clearly showing the stores and real people that your app is worth discovering.
Getting ASO right
You can’t just put your app’s store page up once and expect it to do the job forever. ASO works more like a garden—it only thrives if you keep looking after it, making changes, and letting it grow.

You optimize, you see what happens, you learn, and you try again. To make it work, you’ve got to master the fundamentals—these are the elements that decide whether people actually find your app and, more importantly, whether they hit “Download.”
Keywords and metadata
It all begins with keywords—the bridge connecting what people type into the store and whether your app shows up. Think of it this way: you want to sound like the answer they’re searching for.

You’ll need to balance high-volume keywords (which cast a wide net but come with stiff competition) and low-volume keywords (which may attract fewer people but often convert better because they’re specific).

The best strategies mix both.

  • In the App Store: your title is the single strongest signal for keywords, so every word counts. The subtitle also plays an important role—roughly on par with the hidden keyword field—making it another place to add relevant terms without cluttering your main copy.

  • In Google Play: the app title is the strongest signal for keywords, but descriptions matter too. Both the short and full description are indexed, and the algorithm scans them closely. Work keywords in naturally and keep the text clear and useful. Keyword stuffing won’t help—but a well-written description will.

A strong keyword strategy starts with research. Begin with “seed” terms that describe your core features, then expand with variations people actually search for.

Competitor analysis is another goldmine—look at which keywords similar apps rank for and spot gaps where you can compete.

If you're launching your app in different countries, don't just run your keywords through Google Translate.

What people search for in the U.S. is often completely different from what they type in Germany, Brazil, or Japan.

You need to do your homework for each place—see what words real people actually use when they're looking for an app like yours. It's the difference between sounding like a textbook and sounding like a local.
Visuals
Before people read a single word, they see your visuals. Your icon, your screenshots, your video—they set the tone. This is where you either win attention—or lose it.
Here’s how each piece plays its part:

  • Make your icon instantly recognizable and a quick signal of quality

  • Use screenshots to tell a story—highlight what your app does, how it helps, and why it matters

  • Let a preview video show your app in action and set clear expectations

Visual preferences vary by audience. A style that resonates in one region may not work in another.

For example, playful, colorful visuals might convert well for gaming apps in Asia, while clean, minimalist screenshots resonate more with productivity apps in Western markets.

This is where A/B testing comes in—test different layouts, captions, or styles to see which version actually drives installs.

Apple and Google give you plenty of room for media. Use it thoughtfully—these elements don’t just support your rankings; they directly influence whether someone installs.
Ratings and reviews
People trust people—not just catchy ads or clever descriptions. What actually convinces someone to download your app? Ratings and reviews. They shape first impressions more than anything else on your page—and yes, they directly influence how app stores rank you.

Here’s a hard truth: most people won’t even consider an app with fewer than four stars.

So when should you ask for a review? Not randomly. Ask right after someone does something satisfying in your app—finishes a level, completes a workout, or achieves a goal. That’s when they’re most likely to feel good about your app and share that feeling.
What happens after the download
It’s not enough to get the install. Stores also pay attention to whether people actually use your app—and whether it works well. If people download your app but never open it again, or if it crashes constantly, it’ll hurt your ranking.

Google, in particular, monitors technical quality through Android Vitals—tracking crash rates, battery usage, and overall stability. A good experience isn’t just good for your users—it’s good for your visibility.
Keep it fresh with updates and events
Regular updates signal that your app is alive and getting better. Even small updates help. Bigger launches are a chance to refresh your visuals and text.

On iOS, you can also promote in-app events—limited-time challenges, content drops, or special activities. These can boost engagement and remind users your app is active.
Don’t just translate—localize
If you’re reaching for a global audience, translation alone isn’t enough. You need localization—adapting your message to fit cultural nuances and local expectations. What works in one market may not resonate in another.

Localization goes beyond swapping words into another language. It’s about cultural context—choosing the right tone, imagery, and even pricing for each region.

An app that feels “local” stands a better chance of ranking higher because users engage with it more. Both Apple and Google reward that engagement, so thoughtful localization doubles as both a user experience upgrade and an ASO tactic.
Test, learn, repeat
Both Apple and Google let you A/B test your creatives and text. Use this. Try one change at a time—a new screenshot, a different description—and let data, not guesses, guide you.

In the end, ASO is a cycle: you research, you try something, you see how it performs, you learn, and you repeat. The apps that stay visible and keep growing are the ones that never stop optimizing.
ASO tools and metrics
ASO only works if you can measure it. Without tracking, it’s impossible to know which changes actually drive visibility or improve conversion.

Apple and Google give you the basics with their own dashboards and testing tools—enough to track installs, see impressions, and try out different screenshots or descriptions.

But that’s just the starting point. To really understand what’s working and to move faster, it helps to add extra tools for visuals, text, and keyword tracking. That way you see the full picture, not just the highlights.
Tools to use:
  • App Store Connect. Apple’s dashboard for managing your app. It shows impressions, product page views, downloads, conversion rates, and lets you run product page optimization tests.
  • Google Play Console. Google’s equivalent, with detailed stats on installs, uninstalls, ratings, retention, and Android vitals (crash rates, battery usage, performance).
  • Apple Search Ads. Even if you don’t run ads, it’s a valuable source of keyword insights. It reveals how users actually search in the App Store.
  • ASOMagic. Our free ASO design maker helps create screenshots, icons, in-app event cards, and promo assets.

It includes ready-to-use mockups for all major Apple and Google Play devices, plus curated color combinations. So even without design skills you can produce polished visuals.
  • MetaMagic. A free tool that simplifies metadata creation. It lets you integrate keywords quickly, track word counts in Google Play descriptions, compare old and new metadata, and export results.

  • Features like Google Natural Language integration and keyword insights make it easier to spot opportunities for visibility.

  • RankForge. A LoveMobile-powered platform, which helps you monitor how your app performs in search and how it compares to competitors. RankForge updates data up to six times a day and lets you monitor up to 200 keywords for free.

Beyond keyword tracking, the platform offers a visibility index that blends keyword popularity with your app’s actual rankings, giving a clear view of overall reach.
Key metrics to track:

  • Impressions: how often your app is shown in search results or featured placements

  • Conversion rate: the percentage of users who install your app after viewing the store page

  • Keyword rankings: where your app appears for its target keywords

  • Downloads and retention: installs are important, but ongoing use signals real value to the stores

  • Ratings and reviews: star ratings and feedback affect both rankings and user trust

The right data tells you not only what’s happening, but also why. Interpreting it correctly is what separates surface-level ASO from long-term growth.
Common mistakes in ASO
ASO looks straightforward on the surface, but many apps lose visibility because of the same recurring errors.

The most common issues include:

  • Targeting the wrong keywords or overstuffing them into descriptions

  • Neglecting visuals and relying only on text to sell the app

  • Ignoring reviews and ratings instead of actively managing them

  • Skipping localization and missing out on international audiences

  • Treating ASO as a one-time setup instead of an ongoing process
