They appear to be the “Neilson” rating company of the mobile world.

Mobilytics (http://www.mobilytics.net) and a handful other vendors have built applications that provide mobile webmasters with the same information they receive from their wired web sites.

It’s great to see such a serious interest in mobile from real players.

Congrats to M:Metrics!

comScore is up-front about collecting user data and the software’s ability to track all of a user’s internet traffic, including normally secure (https://) connections used to communicate banking and other confidential information.

comScore estimates that two million users are part of the monitoring program. However, self-selected populations, no matter how large, may not be representative of the population as a whole. To get the most accurate data, comScore adjusts the statistics using weights to make sure that each population segment is adequately represented. To calculate these weights, comScore regularly recruits panelists using random digit dialing and other offline recruiting methods to accurately determine how many users are online, aggregated by geography, income, and age. Correcting the comScore data requires having accurate demographics about the larger pool of users. However, some comScore users are recruited without being asked to give demographic information, and in other cases users may not be truthful about their demographics. To ensure the accuracy of the data, comScore verifies its users’ demographics during the course of measuring statistical data.

The corrected data is used to generate reports on topics ranging from web traffic, to video streaming activity,[18] and consumer buying power.”
