Take a look at some past uses of the HTML FanGate Tab:
It's free, feature-packed, and extremely popular. We serve more than 100 million Facebook tab views per month.
With Woobox's Facebook page tab app, you can use your own tab icon or select one from the library.
Custom Tab lets you select different content to show to users before they Like your Facebook page.
The built-in WYSIWYG editor makes it easy to create and make changes to your tab without typing HTML.
You get complete stats for page views, visits, and likes segmented by fans and non-fans who view your tab.
The default tab name is Welcome, but you can rename your tab whatever you like.
If your page visitor is using SSL/HTTPS, your Woobox Custom Tab will still be shown and will use HTTPS.
Upload your own images and Woobox will host them for you. No hosting account is required.
Upload your own HTML complete with CSS and Javascript. There are no restrictions.
Why is it free? It's a great way for us to introduce you to our other apps. There isn't even a powered by link.
