"Whether you are a blogger or a big media company, SmartLinks bring fun, utility and the social dimension to your pages.

Let readers explore. Instantly connect your readers to related information: book reviews, similar movies, stock research, music videos - make the best of the web one-click away.

Give readers choice. Everyone has a favourite site: Amazon or Barnes & Noble, Last.FM or Yahoo Music, Netflix or Blockbuster - let the user decide where to go.

Bring readers previews. For each link - whether it's a book, movie, music album, and more - automatically get thumbnail images, descriptions and ratings all without navigating away from your content.
