A report released by Keynote Competitive Research finds that top mobile websites, in their opinion, are struggling to adapt to the needs of consumers. They cite response time (the average time in seconds to download a mobile website to a phone), download speed (average speed, in bytes per second, for a website to download to a phone) and success rate (how often a website was successfully downloaded).

Among the findings, Google ranked best in response time with 6.6 seconds, followed by Facebook at 6.7 seconds. Yahoo averaged 9 seconds, while CNN, MapQuest, MSN and ESPN ranked very low with a response time over 10 seconds. Beating the 10-second mark were Fandango, Schwab and the Weather Channel.

As far as download speed, CNN ranked the highest with 2,368 bytes per second, then ESPN (1,756 bps) and MSN (1,484 bps). Sites that ranked low (less than 1,300 bps) included Mapquest, Google, Fandango, the Weather Channel, Schwab and Facebook.

Success rate varied little - the highest was Google (99% of the time) and last was MSN (97%).
