 * Dear All,
 * Recently I have faced a problem about Ad.txt – that I am told that A third-party
   file exists of Ad.txt exists.
 * It tells me to
    – Move the content of the existing ads.txt file into Advanced
   Ads and remove it. – If your site is located on a subdomain, you need to add 
   the following line to the ads.txt file of the root domain
 * This problem has shown up in 2 of my website, one of which is the sub domain.
   However, I didn’t see any warning message in my Adsense account.
 * Now no advertisements are shown in my websites. I am wondering if I can just 
   ignore is for now (because there is no warning message in my Adsense account)
   or I need to take any actions to resolve this issue?
 * Thanks!
 * Best,
    Adrian

 * Hi Adrian,
 * thanks for reaching out.
 * If your ads.txt shows up correctly when you add `/ads.txt` to your main domain
   and it shows up correctly then all is fine and you can close the warning in Advanced
   Ads. The ads.txt is not necessary for the subdomain.
 * Please let me know if you need anything else.

 * Dear Thomas,
 * Thanks! So now I have one domain and one sub domain, and I add the same Ad.txt:
   –
   same domain name of the advertising system – same publisher’s account ID – same
   Type of account/relationship, and – same certificate authority ID
 * In this case, I don;t need to do anything, not even revise either Ad.txt?
 * Look forward to your reply.
 * Thanks!

 * Hi Adrian,
 * thanks for your feedback.
 * > In this case, I don;t need to do anything, not even revise either Ad.txt?
 * The subdomain should normally not need its own ads.txt file but it shouldn’t 
   hurt either. The official ads.txt standard has a parameter for subdomains, but
   AdSense doesn’t support it. If you are using other ad networks then better ask
   them because each network is responsible to parse the ads.txt on its own.
 * Best regards,
    Thomas
