If you want to embed an iFrame into one of your Facebook tabs, you’ll need to use an app. After doing a quick search, I found that the Woobox Custom Tab worked and was really easy to use.
Follow these steps to add an external URL link to your Facebook Tab:
Step 1: Go to Facebook.com
Step 2: In the search bar at the top of the page, type in ‘Woobox Custom Tab‘
Step 3: Follow the instructions (it is pretty straight forward)
After you’ve installed the custom tabs, don’t forget to go and rearrange it so that it is clearer. With the Woobox Custom Tab you can even add your own custom image. If you have any questions, don’t hesitate to contact me or Tweet @madewjoy.
EDITOR’S NOTE: You have to be careful what you want to embed, if it is a static page, you should be fine, when I tried to embed a dynamic page, it didn’t work as well.
