App indexing with several subdomains

[FashionLux]

Hi,

We are currently in the process of getting our app developed. From an SEO point of view I want the app to get indexed and am currently trying to get a step by step guide for it.

I've come across this helpful guide: https://moz.com/blog/how-to-get-your-app-content-indexed-by-google but need to go a bit deeper now.

Questions I have is related to the "apple-app-site-association" file

As far as I could find out the JSON code of that file has the following syntax:

{_    “applinks”: {__        “apps”: [],__        “details”: [__            {__                “appID”: “9JA89QQLNQ.com.my.bundle.id“,__                “paths”: [ “/myPath1”, “/myPath2/*” ]__            },__        ]__    }_

}

My question is related to the key "appID"

I'm wondering how the entry would look like if I have 10 country subdomains and would like to make sure  that the deep link clicked in the browser is going to the right subdomain page within the app.

Current website structure:
uk.example.com/english-path/
de.example.com/german-path/

Many Thanks in advance

As far as I am aware, the association file is just about which paths the app can handle - I think that if you register the root domain and handle all paths then it will handle all paths across all sub-domains (but you should test this).

When you are actually linking individual web pages to the universal page in the app, it uses a fully-qualified URL with protocol and subdomain so should work fine (see this documentation).
