Keynote Competitive Research announced Europe’s first performance index for the mobile Web. The Keynote Europe Mobile Index is a weekly performance ranking of 10 popular European mobile sites compiled from more than 26,000 measurements taken on multiple carriers from different geographical locations. Keynote recently announced a U.S. mobile index. The Keynote Europe Mobile Index provides insight into the overall performance and availability of popular mobile sites and can be used by customers to benchmark their mobile site performance against the biggest names in the industry.

“As the mobile Web increasingly becomes a part of consumers’ everyday lives, companies operating in the mobile space need to provide an ideal mobile experience for end users in order to thrive,” said Umang Gupta, chairman and CEO of Keynote. “Sites need to be responsive and fast. With our mobile indices, companies can see exactly how they stack up against the competition, providing the industry with an unbiased performance assessment. We believe our new mobile performance indices will hasten the improvement of the mobile experience so Web adoption via wireless devices will flourish.”

In order to collect this data, Keynote will use its newly available on-demand mobile test & measurement network to measure the response time and availability of the European mobile sites of The BBC; eBay (Nasdaq:EBAY); EuroNews; EuroSport; Facebook; Google (Nasdaq:GOOG) (LSE:GGEA); MSN (Nasdaq:MSFT); Time; The Weather Channel and Yahoo (Nasdaq:YHOO) (LSE:YAH).
