The Recommendations Bar allows users to like content, get recommendations, and share what they’re reading/products with their friends.

The Recommendations Bar is always docked to the lower right (or left) of the screen. When the page loads the Recommendations bar will be collapsed and the user will have the option to ‘like’ your page/product.
