One of the continuing problems Web developers face is how to develop pages that look good and work properly, no matter what browser, connection speed or screen resolutions visitors use.
WebSideStorys StatMarket service provides some of these statistics based on daily traffic data collected from 150,000 sites visited by 50 million users. The service provides current and historical information on browser versions, screen resolutions, default language, top referrers, traffic volume and operating system statistics. The service doesnt provide connection speed, although it is a planned addition. Prices for access to the data start in the low thousands.
StatMarket was updated last month to segment these statistics by country and industry of the visited Web site. For example, I could see the browser type breakdown for all visitors to airline sites.
