Since I started doing Mobile SEO about 2 years ago, the main problem that I’ve encountered in my duties was that there’s no way to identify unique visitors when it comes to mobile surfing.

Indeed, as opposed to the desktop Web, where cookies or IP addresses (sometimes combined with user agents for better accuracy) are used to identify unique visitors, it’s another story with the mobile Web. Cookies aren’t supported by all phones and IP addresses aren’t unique to each end user, but it’s the one belonging to the WAP gateway used when you surf from your cell phone.

Today, Bango, a leading provider of mobile billing solutions and also of a mobile analytics suite announced today that it is the first company to provide an accurate unique visitor count.

This may sound surprising, but here’s how Bango explains how it works:

For each individual that clicks on an ad or browses a site, a privacy protected Bango User ID is created, compiled through sophisticated WAP gateway profiling, data from browser analysis, session information and network interactions. This unique user ID enables Bango to distinguish between new and repeat users and therefore quantify precisely the number of unique visitors.

Bango is close to many mobile phone carriers so it managed to work something out with them to profile users. But one thing that I’m not sure of is if this feature works with any carrier…I’ll ask this to Bango when I get a chance.
