1 – "Call-To-Action" Graphic
More of a piece of advice than a trick. The main purpose of your Facebook landing page is to convert visitors into fans. Place a clear call-to-action graphic in the landing tab, this will help getting more "Likes" from your visitors.
Example: RedBull’s "Red Bull" tab has nothing but a call-to-action on it.
2 – Embedding YouTube Video
An image is needed whenever you place a video because Facebook does not allow you to run flash instantly, you need to launch it with a click, until then you see the picture instead.
3 – Hiding content from non-fans
This can be use as a teaser to encourage visitors to "Like" your page and become a fan.
4 – Products commenting
This feature is great for setting a little store under your Facebook business page as you can have each of your products liked and commented.
5 – Insert "Share Button"
With this button you can have Facebookers share almost anything. Put the URL you wish to share in the code and once a person uses the Share button, all his friends will see this URL in their news feed.
6 – Image Rollover
People can go rather creative about this trick, but it’s really simple to do with HTML + CSS, which is supported by FBML box.
7. Track with GoogleAnalytics
Facebook analytics system has limited information? No problem! You can set Google Analytics on your Facebook page.
BONUS:
Add "Invite your friends" box
This is basically a standalone box, which is really hard to embed to a page design. However this is probably the best solution for a page footer that you can think of, as your visitors can instantly choose some of their friends and send them invitations to your page.
Pop-up dialog
If there’s too much content on your page, you can hide some parts of it under the pop-up boxes. The code adds a text link, which results in a pop-up dialog text box.
