StumbleUpon helps users discover and share great websites. As you click Stumble, the site delivers web pages that are matched to your personal preferences. Your friends or one of over seven million other web surfers has explicitly recommended these pages with interests similar to the ones you have indicated. Rating the sites you like, you automatically share them with like‐minded people, and assists you in discovering great sites your friends recommend.
The more positive reviews that a web page receives, the more traffic StumbleUpon sends to that web page. StumbleUpon uses thumbs up/down ratings to form collaborative opinions on website quality. This enables users to discover great content they probably would not find using a search engine.
Through StumbleUpon Advertising, you can select specific pages on your website to promote through the StumbleUpon network that is promoted to their over seven million users. The advertised page is included into the set of websites that StumbleUpon delivers to its users – it is not promoted as an advertisement. The end user will see the ad just as they would see any other page that is delivered to them through the network.
Your StumbleUpon advertising can be customized to selected target demographics, including: interests, geographic location, gender, and age. If the page that is submitted becomes popular with people thumbing it up, you will begin to get a natural wave of unpaid StumbleUpon traffic.
