Q: Facebook: Liking content within facebook fan page application I have an application which will run inside a Facebook Fan Page tab. The only difficulty is, I have pages inside the app that I need to add a like button to.
It's easy to add a normal like button, as the content is obviously hosted on a website. However, when it appears on the users feed, I would like it to appear as a link to the application post page, not the website.
For example the actual URL would be something like:
www.example.com/news/article/id

And the post regarding the like would link to this page in a new window - displaying the app out of context.
Instead I need it to display as a link to the app, something like:
http://www.facebook.com/fanpagename?sk=APP_ID&url=/news/article/id

Is this possible?

A: Go to your page and click the Edit Page button.
On the left side, click Apps
Now click the link Link to this Tab for the tab you are interested in linking to, copy this link.
Finally, go to this link...
http://developers.facebook.com/docs/reference/plugins/like/
And using the link copied above generate your like button.
