Implement twitter cards for



I work at We are going to support twitter cards soon, now doing a small research.

Because of our app architecture we have main domain and user subdomains: Each article that user posts will have address

  1. Will it be enough to approve cards only for domain?
  2. Also we have two twitter different accounts for cyrillic and non-cyrillyc user. Is it possible to provide two twitter accounts and set twitter:site based on our settings?
