How to Add Widgets to Facebook
Facebook's default layout for pages gives ample opportunity to share content with your customers and followers. You can type text directly to your Timeline, you can upload pictures or videos, and you can link fans to external sites. To further expand your page, however, you can add third-party widgets from Facebook's App Center. With these apps, you can run contests on your page, collect data with forms, import external feeds and even use HTML to code your own content from scratch.
Log in to your Facebook account. Click the arrow next to "Home" and choose your page from the drop-down menu.
Type the name of the widget you want to add to your page into the Facebook search box.
Click the name of the widget in the drop-down search results to open the widget's page.
Click "Go to App" to open the widget.
Click "Add [widget name] to a Page" to reveal a drop-down box listing your pages.
Click the box and select your page.
Click "Add [widget name]" to add it to your Facebook page.
