Top Performing Mobile Web Sites

For week of December 17th Keynote's industry analysis group, Keynote Competitive Research, reported the following top performers in the usual 3 categories:

US Mobile Sites

• Best Response Time (secs.): Facebook (runner-up: Google)
• Best Success Rate (%): Mapquest (runner-up: ESPN)
• Fastest Download Speed (bytes/secs.): CNN (runner-up: ESPN)

European Mobile Sites

• Best Response Time (secs.): Facebook (runner-up: Google)
• Best Success Rate (%): The Weather Channel (runner-up: Facebook)
• Fastest Download Speed (bytes/secs.): Euronews (runner-up: Time)

By at least some measures ESPN in the US and Facebook in Europe seem to be consistently running high performance sites.  But when you look at the other categories in which either company is not top 1 or 2 (response time for ESPN and download speed for Facebook), the picture is not so cut and dry.
