ASO 101: Getting Started With App Store Optimization

What is App Store Optimization (ASO)?

App Store Optimization is the process of optimizing mobile apps to boost their app rankings and visibility on the app markets such as Google Play Store and Apple App Store, so that more mobile users can get to know about them and download them.

Have you ever heard of SEO before? SEO stands for Search Engine Optimization and includes the practises that a website needs to be more visible on Google search results pages and to attract more visitors. 

We can briefly define ASO as the App Store SEO.

Why is ASO Important?

Our mobile devices have definitely changed the way we live. For example, are you hungry? Do you want to work out to stay fit while at home or do you need a new pair of jeans? You don’t need to go out to find a restaurant, a gym or a store anymore. Just open your app market and type a few keywords. Then you’ll find tens of thousands of mobile apps to meet your needs.

According to the latest data, global app downloads are projected to reach unprecedented levels, surpassing 230 billion annually by 2024.

However, in line with the growing number of available mobile apps and amount of app usage, the continuously increasing competition in the market makes it more and more difficult for app publishers to get their products more visible on the major app stores. 

And this briefly summarizes why you should care about App Store Optimization and start focusing on increasing your app rankings. 

If you develop a strong App Store Optimization strategy and optimize your app accordingly, you can save your app from being lost in the crowd and maximize your chances of appearing at the top when mobile users make a search on the app stores. 

App Store Optimization (ASO) Checklist - 2024

1- Keyword & Category and Competitor Analyses

There are 33 app categories on Apple’s App Store and 24 on Google Play Store. Start with deciding the category that you think your app is going to fit the most. 

It is a very crucial step, especially when you’re going to publish your app on the iOS market as choosing an irrelevant category is against Apple’s App Store Review Guidelines and it might cause your app to be removed. 

As well as Apple, Google doesn’t approve apps with false categories and allow them to be released on its market either.

Also, the majority of mobile users check out categories while discovering apps so choosing the right category will help you increase your visibility and app rankings. 

After picking it, continue with analyzing the other apps in that category. Check out how they are doing, how their app rankings are, what features they offer but you don’t do, etc. 

Then, analyse the app store keywords that users are typing in the search bars while they’re looking for an app. Don’t forget to check out the app store keywords that your competitors are targeting.

ASO tools you can find on this page will provide you with very detailed data and insights that will help you a lot to perform analyses and maximize your results.

2- App Name

Picking the right app name is another crucial element that affects your app rankings. You should pick a unique, creative, searchable and memorable name for your app. 

Check out these 5 common mistakes to avoid when choosing your app name.

3- App Title & Subtitle

Yes, your app name is very important in terms of ASO. However, it’s probably not going to be enough to tell users what your app is about at first glance. That’s where app titles & sub titles come in.

Google Play Store allows publishers to add app titles up to 50 characters while Apple limits this length with 30 for subtitles.

You shouldn’t forget to include your main keywords in your titles, especially for Google Play Store as it puts more emphasis on them since it doesn’t provide a special ‘’keywords’’ area and focuses on the keywords used on the app page. 

Keep in mind that you shouldn’t do keyword stuffing and create informative titles to help users and the algorithms understand what your product is about.

4- App Description

App descriptions are another important element to tell people about your product and increase your app rankings, especially on Google Play Store. 

Google finds the keywords that you want your app to rank for in your descriptions. It offers two description areas; one for your short description which is limited to 80 characters and one for your long/full description which can be up to 4.000 characters. 

Use the short description area to give users a brief summary of your app and the long description area to cover more detailed information about your product. 

Don’t forget about the keyword density while creating your app descriptions and you can get help from ASO tools like AppTweak to write the most effective ones.  

In the meantime, Apple has an app description area too which can have up to 4.000 characters. The keywords you use here doesn’t affect your rankings on the App Store but writing an informative description will maximize your chances of conversing users.

5- App Icon

Mobile app icons are very effective in catching the attention of users, when created appropriately. Make sure to use a simple and attractive one that reflects your app, and avoid using too many elements as it might cause confusion. 

And don’t forget to check out your competitors’ icon designs and take into account the effects of colors on people.

To create your android app icon or ios app icon, you can work with a professional designer or get help from app icon maker tools such as Canva.

6- App Screenshots & Videos

App screenshots and videos don’t affect your app ranking in a direct way, but using them is one of the most effective ways to convert users and show them what your app/game looks like and functions.

Google Play Store allows you to add up to 8 screenshots and a promotion video between 30 seconds and 2 minutes, while App Store lets you add up to 10 app screenshots and 3 30-second videos.

7- Localization

If your app is available in different countries or you want to launch it in other markets, you need to do localization in order to climb the charts on the app markets. It’ll provide you with many advantages such as going beyond your current user base and higher ROI. 

There is a common misperception that localization is simply a matter of translating. But it’s definitely not. You need to localize and customize not only your texts, but also its images, sounds, currency, date & number formats and even its colors. In addition, you need to create a brand new keyword analysis. 

Luckily, ASO tools like AppTweak, and MobileAction also offer localization services.

8- App Ratings & Reviews

App ratings and reviews are the outcomes of the experiences that users had while using your mobile app and they play a key role in your app rankings on both Google Play and App Store. 

“Google Play ratings and reviews are extremely important in helping users decide which apps to install.”


‘’Ratings and reviews influence how your app ranks in search results, and can affect whether someone downloads your app. Users can rate your app on a scale of 1 to 5 stars. They can also add a written review for iOS and macOS apps.’’


According to a research, %79 of consumers check app ratings and reviews before downloading an app. 

So make sure you’re encouraging your audience to share their thoughts by leaving a comment and reply to every single review even if they’re negative. 

ASO tools which you can find above lets you access all of your app ratings and reviews in one place and makes it very easy to analyze and reply to them.

9- A&B Tests & Updates

Running A&B tests allows you to detect what’s working with your app store optimization strategy and what’s not. It offers higher conversion rates, less bounce rates and the ability to easily analysing the changes you’re planning to make to your app. 

According to the results you get, you can update your app and strengthen your ASO strategy for more conversions and higher app rankings. By the way, while updating your app, don’t forget to take into account the app ratings & reviews you get on the app stores, and the other comments you receive from different platforms such as social media, websites etc. 

A&B testing and the other App Store Optimization practises here are not simple tasks and need to be completed professionally. However, thanks to the ASO tools we’ve listed for you, you can maximize your results and get your app ready to rank higher on the app markets.
