Navegg: Google Analytics for Behavior [50 FREE Invites]

Quick Pitch: Navegg is a web-based system that calculates demographic profiles based on users' online behavior.

Genius Idea: All website owners, regardless of industry or audience, want insight on their site traffic and visitors. Some of that information is crucial to securing advertisers, clients, customers, or press attention. Google Analytics is a great free solution, but it does little to identify the demographics of your visitors. Enter Navegg, a private beta site that provides you with behavioral analysis of your site's visitors so that you can serve dynamic content and ads to the most appropriate audiences.

Navegg isn't site specific: instead it's a network of partner sites that work collectively to tackle behavioral analysis of audiences. So, partner sites place content identification tags in their pages to help Navegg collect user behaviors. Navegg's algorithm then works to define demographics and subjects of interest based on the entire network. Essentially, Navegg is doing comparative analysis against each site in their extensive network to arrive at certain conclusions about your audience.

With Navegg, you'll be able to see segmentations of your audience to help you understand things like the percentage of your audience that is male, adult, and in college. You can also view breakdowns by gender, age, education, topics of interest, and country. Using that data, you can work with their API to adjust your site content or advertising to fit visitor profiles.

Supposedly, Navegg does all this without collecting personally identifiable information, making user data anonymous. They also allow end users to opt out of the Navegg network.
