What is the best way to check ownership of a site?

Question

Domain Name System

As a rule, well-known search engines offer 4 options for checking rights:
html file (extra "garbage" in the code)
meta tag (similarly, "garbage")
txt file ("garbage" on hosting)
via dns (?)
I understand that it's all the "little things of life", but still. How do you do it yourself?

Answer 1

And an extra entry in the DNS - not "garbage"?
You are overthinking.
Any of these methods has the right to exist. The main thing is not to add files to the VCS index.

Answer 2

personally, it’s more convenient for me to use the meta tag
PS after the initial indexing, you can also assign unique texts to yourself

Answer 3

Well, you can also offer sending an e-mail to [email protected], which, I remind you, according to RFC2821, the domain must have it, like the postmaster.
This is exactly what StartSSL does to validate domain rights when issuing an SSL certificate.
And so, indeed, all methods are permissible and really in everyday life.
