Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
I have checked your main domain and subdomain from where you are redirecting the pages. I can’t seem to find any robots.txt file on your subdomain. You should consider getting in touch with your host for further clarification. Also Rank Math doesn’t add anything on different domain/subdomain.
I hope this helps. Thank you.
Thanks Ankit. I’ll follow this up with my host as suggested.
