I received a mail two days ago titled "AdMob starts implementing support for app-ads.txt files". My problem is that I am app developer and I don't have any domain. What should do for this purpose? Secondly, I have lots of app on the Play Store; do I need to buy new domain for every app?

Do i need to buy new domain for every app?
Yes it require to buy domain or change code from any of apps,you just have to setup app-ads.txt correctly in admob dashboard.
you can read official document about how to Overview of Setup app-ads.txt and to understand in detail about app-ads.txt you can refer IAB TECH LAB.pdf
Also for batter understanding can suggest you to refer this example
Note : here your publisher id and package name need above image is just example screenshot of admob guide

No ! you don't have to have/buy a domain for this. there is a free solution using Firebase Hosteing, as i explained here : https://stackoverflow.com/questions/57412259/admob-starts-implementing-support-for-app-ads-txt-files/61850551#61850551 – korchix May 17 '20 at 10:50
As long as i understand, all you need is to create a text file named app-ads.txt.
Just place this file in com.example.your_projectName.
Now, open the file. Add one line as,
com.example.your_projectName,your_admob_publication_id,DIRECT
(No spaces between ',').
Thats it for all.
Save the file and go with ads.

Viraj S i did not understand how i add this file in my app project name? – samsoon Aug 16 '19 at 05:58
No Need to Buy New Domain for Each App. for example if you have one developer account with Multiple apps then you just fill or update Storelisting-> website which root contain app-ads.txt file, admob will automatically crawl in 24 hours and Verified.
If you have Multiple Playstore Account with One Admob. in that case you should buy 2 domain and place same app-ads.txt file in both domain, admob will verify both play store developer account apps. if you tried to do same domain in multiple account , then it may chance that google will suspend your account as per policy one developer must have only one playstore account.

Well, I found the easiest way to let users use app-ads.txt
. I think we cannot use it without having a domain. So, I have a solution, Go to https://www.freenom.com and you can get a domain there for free! But only with extensions: .tk
, .ml
, .gq
, .ca
, .ga
.
After registering a domain there, you can use it as you like.

That's your wish what to do. My answer was my opinion on what you could have tried. That's AdMob's work to let your app-ads.txt work. Anyway, if you think that my answer is worth it, please accept it. – Gourav Aug 16 '19 at 14:46

I think you didn't understand. Let's start from the beginning. I said you can go to the link I provided and register a domain for free and then use it as you want it. The domain will be yours for free for 1 year and then you can add that to the `app-ads.txt` file. – Gourav Aug 17 '19 at 08:40
