Just follow this app store keyword optimization guide to find out how.

How Do App Store Keywords Work in the App Store?

First thing first: let’s find out how app store keywords work in the App Store…

Apple App Store actually indexes multiple app localizations in each App Store market.


It is because App Store users use different languages in each market.

For example, the U.S. App Store indexes BOTH English (U.S.) and Spanish (Mexico) localizations. Because of that, users of the U.S. App Store can search for an app using the keywords in both localizations.

So if you publish your mobile app to the U.S. App Store, you can use the 100 keyword character space in BOTH English (U.S.) and Spanish (Mexico) localizations.

A total of 200 character space. A double up!

In the Spanish localization, you can enter Spanish keywords. Or if you prefer, you can also enter English keywords there too.

Got the idea?

By using this trick, you will have a big advantage over your competition.

And the good news is:

This way, you can easily double the space available for your App Store keywords in English or any other language you prefer.

All you need to know are the localization languages that are indexed by your target App Store market.

But you may ask:

“How do I know which localizations are indexed by my target App Store markets?”

This leads to the next section…

Which App Localizations Should I Use?

App Store indexes at least two app localizations in each App Store market.

And some markets have even more!

For instance, Switzerland App Store indexes four localizations: German, French, Italian, and English (U.K.).

That means you can 4x your app store keywords in Switzerland App Store.

But how about the other App Store markets?

  1. Hi,Thanks for the great article!
    Do you know about this process in Google play as well?
    we noticed that english UK/Australia/Singapore/etc. App Name localisations do have an effect on the US keyword rankings!

      1. Hi, great article, thank you!
        I’d like to ask as well about Australia.
        Could you let us know (when you find it out) if the keywords we use in Australia have effects on other countries rankings? I’m talking about the App Store.
        That would be very useful.

  2. Hi Marcus,

    Do you, by any chance know, if English US and English CA has any effect on App Store China rankings?

    1. App Store China indexes Chinese (Simplifed), English (U.K.) and English (Australia) in our findings. So No, English US and English CA don’t have impact to it.

    1. Once you have released a new version with the new keywords, the new keyword rankings should take effect on the same day.

      And you should review your keyword rankings every week to make sure they are optimized.

      Keep those in top 10, drop the low ranking keywords, and add in your newly found keywords if you have spare space in the keyword field.

  3. Hi Marcus,
    I read this:

    Keywords cannot be combined. Meaning that if you have “food” in your Spanish (MX) keywords, and “delivery” in your English (U.S.) keywords, you won’t rank for “food delivery”.

    That is right?

  4. I have released a new app version and added some Japanese keywords to English (Australia) on iTunesConnect. I have mixed Japanese and English. All keywords from English (Australia) are ranking in Australia, but don’t in Japan at all. It did not have any effect. There are some long tail keywords with very low competition, but they don’t rank either. Any ideas? Should I try English (U.K.)?

    1. Thanks for giving it a try.

      According to our latest findings, Japan App Store indexes both Japanese and English (United States) localizations.

      So you should consider using English (United States) localization instead.

  5. Lets say I have one set of Keywords for English UK and another for English AUS.

    Now I am accessing the app store from the UK, If I search for keywords that are indexed in the AUS version will the app show? In other words when I search it checks all the localisations and not just the UK one?

    1. The UK App Store indexes both English UK and English AUS localizations (but not others).

      So if you search in the UK App Store, your app has a chance to show up in the search results of the keywords you specified in the English UK and English AUS localizations.

      Note however that the actual rank in the search results still depends on how strong your app is.

  6. Dear Marcus Kay:

    Thanks for all the great articles you offer.
    I am just wondering what languages App Store Taiwan index, and where can I find information like this?

    Thanks again, you save lots of indie developer

    1. Hello Danny, thanks for your kind words.

      We update the languages indexed by each app market including Taiwan in a spreadsheet.

      Just click on the map above to sign up, and you will get the most up-to-date version.

  7. You actually make it seem so easy with your presentation but I find this matter to
    be really something that I think I would never understand.
    It seems too complicated and extremely broad for me. I’m looking forward for your next post, I’ll try to get the hang of it!

  8. This is nice to know that this kind of actions is also possible with the apps and the keywords in the app store. Hope this will help the others as well.

  9. I have been looking for the app store keyword which has been helping users a lot. There are very interesting tactics which I got to know from here.

  10. Great article!

    Put the case I publish 200 keywords all in English in the US app store both for the English (US) and Spanish (Mexico) localization. Is there any risk if I also have my app in Mexico and I use only Spanish keywords over there? My question basically is: if the keywords I used for a localization in one country (only using English kws in the Spanish-MX localization in the US) can affect the localization in the “real” country when someone is searching there (having only Spanish kws in the Spanish-MX localization in Mexico)?

    1. If you use English keywords in your Spanish localization, your app’s ranking on Spanish keywords will be negatively affected. That’s a tradeoff of this trick indeed.

  11. Hiya, thanks for the article, it’s super useful.

    I’m new to ASO and I’m trying to wrap my head around this. If I release my app on say, the German App store (German & UK localizations) does that mean the app is only available in Germany and the UK? Or is it still available worldwide?

  12. App store optimization (ASO) has been slightly unnoticed of late with the development of machine learning and Artificial Intelligence AI, Google’s mobile-first index progression, and other obvious industry vicissitudes commanding the attention of every marketer.
    Whether you are fresh to app store optimization, or intense to refine your approach to ASO, this writes up will provide some applied visions which are proven to get the most out of app store success.

  13. Good day! Would you mind if I share your blog with
    my zynga group? There’s a lot of folks that I think
    would really appreciate your content. Please let me know.
    Thank you
