The Official Swidget
The official Swagbucks Widget (known as the Swidget) is probably one of the best way to bring Swagbucks to your website! It will let people search using Swagbucks.com, show the latest blog post, see prizes, check for Swag Codes (Which is important!) and let people sign up with your referral link!
If you like the Swidget, but need something smaller or thinner for your website, you should check out the Mini-Swidget.
