If you have an app or on the point of developing app, you heard of app store optimization which is ASO in short. ASO is optimization of mobile apps to have higher search results in the app store. It is like SEO. The difference is that ASO is related with app optimization while SEO is website optimization.

I seem to hear asking “Why?” I think simple two graphs indicate the importance of ASO.


As you can see, both iOS and Android users found the app they downloaded lastly by searching on the app stores. Being able to be found easily is possible with ASO.

What Is App Store Optimization (ASO)?

As I said before, app store optimization helps you acquiring higher rankings in app stores. There are over 3 million apps and it makes competition tough. 47% of iOS users and 53% of Android users find and download the app they are seeking through app store searches. It brings the importance of ASO to light undoubtedly.
 
The ingredients of ASO in bold outline;

  1. Keyword Optimization
  2. Title Optimization

  6. App Preview Video (if yes)
  7. Localization

There are underlying points while determining the keywords.

  • Relevance: Make sure that keywords overlap with your purpose and core functions.
  • Competition:  Target being at top 10 for any keyword. To achieve this, track your rankings and ignore ones which don’t give you high traffic volume. Don’t forget to look at competitor’s rankings.
  • Volume: You can target high volume keywords as well as keywords that have lowest competition. There are multiple synonyms or similar keywords. You can pick the one that has the highest volume.

 

The Recipe of ASO

Let’s dig deeper for each point of app store optimization.

Keyword Optimization

It is important to find relevant keywords at the beginning because you benefit from them while forming a title and description.

There are several keyword tools which are;

Keyword Rankings which lets you see top 100 apps rankings for your specific keywords.
Keyword Research which shows the rankings of top 100 for specific keyword.
Keyword Suggestions which gives potential keywords related with your seed keywords.

App Title Optimization

According to research, having keywords in title boosts your rankings up to 10.3%.  App stores’ algorithm is so they scan the app name to match the keyword in its title and the keyword a user searches. If your app name includes the search keyword in title, it gets high priority in rankings.

While adding an app name, keep it short and simple. Then feed your app name with a few keywords.

  • Google Play Store is limited with the maximum of 50 characters.
  • iOS App Store is limited with the maximum of 30 characters.
  • iOS App Store lets you add a subtitle appearing under your app name. It was introduced with iOS 11. Again the limit is 30 characters at most.
  • Apple uses your app name while creating app URL, so avoid using any special character.

 

App Name Format

“Brand Name: Keywords” or “Brand Name – Keywords”

App Name Examples

Messenger – Text and Video Chat for Free
My Boo – Your Virtual Pet Game
LOOKS – Real Makeup Camera

By the way, it is important to keep in mind that keywords in the title rank 2x better than keyword field. I want to support this by an example. Pink Cloud raised its ranking of one keyword from #23 to #3 by moving it from the keyword field to the title.

Description Optimization

App description results in highlighting the features and benefits of  your app. While writing an app description, it would be better to try to understand your potential users. Read your app description with their eyes. Or you can read different kind of apps to find out the points drawing your attention. The points you should keep in mind;

  • The limit of short description is 255 characters which come up to a few sentences for iOS App Store while 80 characters for Google Play Store. So, try to give the underlying and attention-grabbing values of your app. It creates the first impression.
  • Expanded description is your playground. Add bullet points, social proofs, awards, mentions about you or anything else.
  • Use the tone of your brand and the terminology your potential users get understand.
  • Both app stores have a limit of 4,000 characters for the full description
  • Google Play Store lets you use rich formatting and emoji in the app description.
  • Use sub-headings to divide it into sections.
  • Use white spaces between paragraphs.
  • Be sure there is no typo.

There are two copywriting rules you should bear in mind.

  • KISS – Keep It Simple & Stupid

Try to avoid excessive and redundant words.
Don’t let the repetition of your app title waste the character limit.

  • You can add short caption texts on your screenshots to say that it is which part of your app. But, keep them short and clean.  
  • Avoid login, registrations, purchase forms, ads and even “Welcome” screen in your screenshots.

There are different app pricing strategies. You can develop a free app with in-app purchases, free app with ads and paid app.

  • Free apps with in-app purchases let you make money via different kinds of in-app purchases like buying in-game currencies for passing a level.
  • Free apps with ads let you make money via ads. It would be better to choose native ads as they fit the exact context of the app.
  • It requires paying money to use a paid app. $0.99 or $1.99 can be a good amount for a starting point.

 

Necessary Updates

There is a correlation between the update frequency and rankings. The graphic below shows the average number of days between last two updates for top 25 iOS apps.

Reviews & Ratings

It might be the most important part of ASO. Together with the importance, it is not controlled by you completely. The important numbers that show how important app store ratings are as below;

  • 4 star out of 5 is the average rating of the top 100 free iPhone apps.
  • %67 of the top 100 free iPhone apps have a 4 star ratings or better.
  • %92 of the top 100 free iPhone apps have a 3 star ratings or better.

Ratings affect consideration. All consumers consider downloading 5 star apps while more than 85% of consumers consider downloading 4 star apps.

I said you don’t have a control over your app totally. But you can improve your reviews and ratings.

  • Track a user’s behavior and ask for reviews at the most opportune times. The features of event triggered messages, real time personalization and intelligent events help you catch these times. It can be after a purchase or level completion.
  • While asking for reviews, avoid over-messaging. It annoys users and create a negative impact.
  • You can conduct A/B testing for your messages to find the most valuable one.
  • Give users a place to talk directly to the developer
  • Reply to app reviews and feedbacks as soon as possible

It is the most effective and also the most effortful step. There is a tricky dilemma. If your number of download is high, your review and ratings are good anyway. The thing is here to push users to leave comments and give a rating if they like.

Final Thoughts

To see the results of ASO, you need time and effort. Your job doesn’t end after completing everything. You need to observe and review ASO each month not to miss any trend of app ranking change. Now complete the changes, track the rankings and monitor the trends!
