Perhaps the most underrated social media and content discovery sites we’ve found for attracting traffic for our own site and our clients is StumbleUpon. StumbleUpon has over 30 million users. StumbleUpon offers both an organic user experience as well as a paid discovery service, StumbleUpon Ads.
It’s a pretty addictive platform that generates some deep engagement with its users. The average Stumble session for women is 30 minutes, 22 minutes for men.
