Last week I found out about WidgetBucks from a post by fusion and decided to start testing it yesterday in Exoleb.com.
WidgetBucks shows visitors to your site a list of products with ratings and a link to buy it from the website with the cheapest price, the ad sizes are similar to the ones offered by adsense so I replaced two of my adsense ads with WidgetBucks ones to test them for a week and see how they perform.
If you are interested by WidgetBucks you can sign up here and you’ll get a 25$ Sign up bonus.
