Facebook today rolling out an update to "the way you restrict the audience for the Like button and resulting stories to give you more control." In short, like the Twitter's recent roll out of Age-screening for Brands, Facebook is now allowing certain brands to avoid presenting a Like button or Like stories to "people who are not allowed to see alcohol-related content."
Currently when you point a Like button at a URL with the proper metatags "we create an admin page through which you can establish the same age gating controls that are available to Facebook Pages. These controls prevent us from rendering the Like button and presenting the resulting story back to the wrong audience," Facebook stated.
Going forward, "in order to limit the distribution of these stories to people in the appropriate country or age group, you must include a metatag on your URLs indicating the restriction," Facebook explained.
You must implement metatags on your URLs in the next 90 days in order to continue age restricting the Like button on and post from your app.
If you previously used the Like button and an admin Page as a way to gather and publish to fans, you will no longer be able to. Instead, "you should create a Facebook Page and update your Like button to point to that page. People who select the Like button on your URL will then become fans of this Page and are eligible to receive Page posts from you," said Facebook.
To help make this change, Facebook created a migration setting in the dev app. To learn more about how to use it, read this developer doc about the Like Button Migration.
Please review documentation on how to do this.
Also, as the App Center Global rollout is underway, the company today launched the App Center to users in Brazil, France, Germany, Russia, Spain, Taiwan, and Turkey.
People in these countries will see the App Center bookmark in the left navigation menu on Facebook.com and in our iOS and Android apps.
