【Web】Open Graph Protocol

The Open Graph Protocol enables you to integrate your Web pages into the social graph. It is currently designed for Web pages representing profiles of real-world things — things like movies, sports teams, celebrities, and restaurants. Including Open Graph tags on your Web page, makes your page equivalent to a Facebook Page. This means when a user clicks a Like button on your page, a connection is made between your page and the user. Your page will appear in the "Likes and Interests" section of the user's profile, and you have the ability to publish updates to the user. Your page will show up in the same places that Facebook pages show up around the site (e.g. search), and you can target ads to people who like your content. The structured data you provide via the Open Graph Protocol defines how your page will be represented on Facebook.


看了上面的說明，好像網站都要加一下Open Graph Tags 會比較好。
發現很多大站也都加了。像是Youtube 跟 Vimeo，還有Xuite Vlog...
