sometimes it’s just not feasible/easy to drop an account-id meta tag into an index page. for example, when a given site is simply set to work as a url shortener/redirector. twitter does not check that the redirected page contains the account-id meta. there are other relevant cases but this is the one we’re having.
the following methods are considered common and widely implemented by similar products:
- placement of a specific html or txt file in the domain’s root folder
- DNS TXT record
- email from WHOIS record
please implement an additional one and/or alternatively honor 3XX HTTP codes when verifying a domain.
