The Roost Bar helps you build your brand and followers when you create or share great content. When you share a link via Facebook or Twitter, Roost shortens the URL for you automatically and then redirects any users to a custom link that frames the content you want to share with your brand at the top of the page.
Users will see a logo or picture of your brand, a link to your Facebook Fan Page and a like button. See the screenshot on the right of the page.
The Roost Bar is a great way to expose your brand to users that are not familiar with your brand but are viewing content that has been shared or retweeted.
