I want the rich preview to display the vanity URL, not the destination site.
Is there a way to display the vanity URL instead? On Facebook, this is possible when creating a post on mobile, but not on desktop (except with a paid ad, which will work on desktop). In Twitter, both desktop and mobile return the same result.
Whether in Twitter Cards, or using Open Graph tags, the URL always seems to pull from the destination URL, not the vanity.
Even when inserting the vanity URL into the OG tag makes no difference. E.g.
<meta property="og:url" content="http://foxtel.tv/" />
Any ideas appreciated.
