Facebook API: post in domain feed

Situation: I've the facebook like button in my website in different URLs, for example: http://ift.tt/1aBdw6m

Now, I get that domain Id by calling in the facebook graph api:

/?ids=http://ift.tt/1GPKRJ0

and that returns me as id the same domain.

Now I want to publish as that domain, so users who liked that page, can see the status in their news feed. I try by posting into:

/<domain_id>/feed

and that gives no error, and returns an id, but is just strange

{
    "id": "965928793449764",
    "created_time": "2015-04-16T17:38:50+0000",
    "is_scraped": false,
    "type": "website",
    "updated_time": "2015-04-16T17:38:50+0000",
    "url": "http://ift.tt/1GPKTR6"
}

Is this possible? Can I fix it? It was possible once, but now it doesn't work.

Thanks!
