Premium inclusion in StumbleUpon starts at 5 cents per targeted visitor. We show your site directly to StumbleUpon members (a demo is available here). Targeting by personal interest, history of rating similar sites, location, and demographics (age, gender) determines who will see your site. There is no ad impression or click-through. Rather than using intrusive forms of advertising (like popup ads), we display your entire page.
