App Store Optimization Checklist: How to Improve App Visibility and Downloads

App Store vs. Google Play: What Changes in Your Checklist

The two stores reward similar things, but the fields you can edit are different. That means some checklist steps change depending on the store.

Here is the quick comparison.

Element	Apple App Store	Google Play
Title	30 characters	30 characters
Subtitle / short description	30-character subtitle	80-character short description
Hidden keyword field	Yes, 100 characters	No
Long description	Not indexed for keywords	Indexed, up to 4,000 characters
Keyword repetition	No value	Helps, if natural
Screenshots in search	Shown for all searches	Mostly for branded searches
Backlinks	Not a ranking factor	Can help
Built-in A/B testing	Product Page Optimization	Store Listing Experiments

How to Improve App Store Optimization: Step-by-Step

This is a core part of the guide. Follow each step in the given order, here is a quick tip before you start the app store optimization.

Change one or two things per update cycle. If you change everything at once, you won’t know what worked.This is part 1 of 3, covering steps 1 to 4.

1. Audit Your Current Listing and Competitors

Don’t change anything yet. First, see where you stand. Start with your competitors. Sort them into three groups:

• Direct competitors solve the same problem for the same users.
• Indirect competitors solve it in a different way but show up in the same searches.
• Aspirational competitors are category leaders. They show you what “good” looks like.

Then audit your own metadata.

2. Keyword Research Checklist

Build a wide list of keyword research. Think about how real users describe their problem. Use their words, not your internal terms. Pull ideas from:

• Your app’s features and benefits
• Competitor titles and subtitles
• Autocomplete suggestions in both stores
• Your own reviews and competitor reviews
• Apple Ads search term reports, if you run them

That last source is underused. Paid search shows which terms lead to real installs, not just impressions. Then narrow the list. Filter each keyword on four things, relevance, search volume, competition, and conversion potential.

3. App Title and Subtitle Checklist

The title is the strongest text signal on both stores. Both give you 30 characters. Use them well.

A good title does two jobs. It names your app, and it tells people what it does. Users should understand your app from the name alone.

On iOS, add a second keyword and a clear benefit in the subtitle. On Google Play, the short description plays this role. It gives you 80 characters.

4. Keyword Field and Category Checklist

This step applies mainly to Apple. Google Play has no separate keyword field. The keyword field gives you 100 characters that users never see, but Apple indexes it.

Follow these rules:

• Separate keywords with commas.
• Don’t add spaces after the commas.
• Don’t repeat words already in your title or subtitle.
• Put higher-priority keywords first.
• Don’t waste space on your app name or competitor names.

5. App Description Checklist

The description works very differently in each store. This is one of the most missed differences in ASO.

On Google Play, the long description helps you rank.

• Google indexes all 4,000 characters.
• Put your main keyword in the first two or three sentences.
• Write for people first. Google reads context, so stuffing keywords can hurt ranking and installs.

On the App Store, the description is only for conversion.

• Apple doesn’t use it for keyword ranking.
• Repeating keywords here wastes space.
• Users see only the first two or three lines before tapping “more”. Make your first sentence count.
• Updating the description means submitting a new app version. Plan changes carefully.

6. Icon, Screenshots, and Video Checklist

The users spend about three seconds on a listing. They judge it before reading a word. So your visuals need to work fast.

• Icon. It is the first thing people see. Use one clear element, and strong contrast so it stands out from competitors.
• Screenshots. The first three matter most. They show in search results, showing one benefit per screenshot.
• Video. Show real app use, avoid time-sensitive content so it stays fresh.

7. Custom Product Pages and Store Listings 

Not every visitor wants the same message. Custom pages let you match your listing to the visitor.

• On the App Store, these are called custom product pages (CPPs). Each has its own URL. You can change screenshots, preview videos, and promotional text.
• On Google Play, the equivalent is custom store listings. You can target by country, pre-registration status, or Google Ads link.

8. Localization Checklist

Localization means adapting your listing for each market. It is not just a translation.

Translating your English metadata word for word is often the first thing teams try, and the first thing that fails. People in other countries search differently. The keywords, the competitors, and the habits are all different.

Don’t localize everything at once.

• Top revenue markets: full localization. That means metadata, screenshots, and possibly video.
• Growth markets: localized title, subtitle, and keywords, with default visuals.
• Long-tail markets: translated core metadata only.

9. Ratings and Reviews Checklist

Ratings do two jobs. They help your ranking, and they help people decide to install. A weak rating hurts both.

Apps below 4.0 stars can see tap-through and download rates fall by up to about 50%. Above 4.0, the differences are smaller. Also a steady flow of new reviews can matter more than the exact score. Recent reviews carry more weight than old ones.

10. A/B Testing Checklist

Do not guess things about the app, do A/B testing as it will tell you what actually works.

Both stores have free testing tools:

• Apple: Product Page Optimization. You can test up to three alternate versions of your icon, screenshots, or app previews against your current page.
• Google Play: Store Listing Experiments. You can test icons, screenshots, videos, and descriptions.

11. Technical Health Checklist

Both stores care about what happens after the install. Retention and stability now count more than they used to. A great listing can’t fix a buggy app.

Checklist for Technical Health 

• Check Android Vitals every week
• Fix crash and ANR issues before they pile up
• Set an update calendar (about 4 weeks for iOS, 6–8 for Google Play)
• Add clear “What’s new” notes to each release
• Plan in-app events or promotional content around key dates
• Nominate your app for featuring when you have a strong update or event
• Google Play: earn quality backlinks from relevant sites
• Track retention (Day 1, Day 7) alongside installs

12. Monitoring and Reporting Checklist

For monitoring and reporting, track these core metrics.

• Keyword rankings. Check weekly to spot sudden changes.
• Conversion rate. This shows how well your page turns views into installs.
• Organic downloads. Compare organic against paid to see ASO’s real contribution.
• Retention and engagement. These matter most on Google Play.
• Ratings and review sentiment. A slow decline is an early warning.
• Competitor changes. Watch their metadata and creatives.

How to Improve App Store Optimization Over Time

ASO is not a one-time thing, because rankings can move. So, the apps that grow repeat one cycle: research, update, measure, and adjust. Below are some tasks that you should do weekly, monthly, and quarterly.

Weekly (about 30 minutes)

• Check rankings for the top 15 to 20 keywords.
• Check Android Vitals if you’re on Google Play.
• Reply to new reviews.

Monthly

• Review conversion rate, organic installs, retention, and rating trend.
• Check what competitors changed.
• Compare Apple Ads keyword data with your organic rankings.
• Update one or two listing elements, not everything.

Quarterly

• Refresh keyword research.
• Add or improve one localized market.
• Plan seasonal updates about two months ahead.

How Long Does ASO Take to Show Results?

Below is a table that shows a timeline to get results based on the changes you make.

What you change	Typical time to results
Icon and screenshots	2-4 weeks
Keywords and metadata	4-8 weeks
Compounding organic growth	Month 2-3 onward

App Store Optimization Tools

You can start ASO with free tools. Paid tools save time once you manage more keywords, markets, or tests.

Free Native Tools for App Store Optimization

Both stores give you data and testing at no cost.

• App Store Connect (Apple): analytics, Product Page Optimization for A/B tests, custom product pages, and in-app events.
• Google Play Console: analytics, Store Listing Experiments, custom store listings, promotional content, and Android Vitals.
• Apple Ads search term reports: show which searches lead to real installs.

The limit: native tools show your own app. They don’t show competitor keywords or search volume.

Paid ASO Tools by Checklist Step

ASO tools are divided into five types

Checklist step	Tool type	What it does
Audit	Market research tools	Track competitor keywords, metadata, and creatives
2. Keyword research	Keyword research tools	Suggest keywords, show volume, difficulty, and your rankings
Creatives, A/B tests	Testing tools	Test icons and screenshots, sometimes before launch
Reviews	Review management tools	Monitor, sort, and reply to reviews at scale
Monitoring	Reporting tools	Combine store data into dashboards

ASO and the Future: AI Search and Beyond

Both stores now use AI to understand what people mean, not just what they type. Here is what that means for your ASO.

1. Search is Becoming Intent-Based

Apple and Google now read user intent. “Budget planner” and “expense tracker” may point to the same need.

• Write natural, human copy. It now beats keyword stuffing.
• Group keywords by user need, not just topic.
• Make your title, screenshots, and reviews all point to the same use case.

2. AI Assistants and ASO Tools

AI assistants are starting to influence which apps get recommended. The rules are still unclear, so watch this space rather than build a strategy on it. Keeping your listing clear, accurate, and consistent helps either way.

AI also speeds up ASO work: finding keyword gaps, grouping reviews, and drafting metadata ideas. Keep a person in charge and check every suggestion against store rules and real user language.

Conclusion

App store optimization helps people find your app and gives them a reason to install it. You do that by improving your keywords, your listing, and your app’s quality.

Use the checklist as your base. Audit first, then work through keywords, title, description, visuals, localization, reviews, testing, and technical health. Track your results as you go.

Keep three things for optimization, do one or two updates per cycle, creative changes can show results in weeks, fix the app, not just the listing.

Start small. Pick the weakest part of your listing today and improve that. Then repeat the cycle every month.
