Priceline.com Selects Keynote Systems’ Web Performance Test & Measurement Products

Keynote® Systems (NASDAQ:KEYN), the global leader in on-demand mobile and Internet test & measurement solutions for continuously improving the online experience, today announced that priceline.com has recently adopted Keynote technology. Customers choose Keynote because its online test and measurement products are cost-effective, flexible, and comprehensive and deliver accurate data about its Web applications’ performance and availability. These capabilities allow them to proactively address glitches that arise and optimize the end-user experience on their applications.

"Keynote is very cost effective,” said Michael Diliberto, chief information officer of priceline.com. "In addition, KITE (Keynote Internet Testing Environment) allows us to easily create scripts and upload them into Keynote Transaction Perspective®. The scripts are run against our Web servers from a set of preselected nodes to simulate end-user transactions. This custom scripting is a very useful capability. Having an outside company with Keynote’s expertise regularly providing us with this insight is helpful in examining the variability in our site’s performance. This allows us to minimize our mean time to repair (MTTR) and optimizes customer experience, which in turn leads to increased revenue.”

Priceline.com helps users obtain discount rates for travel-related items such as airline tickets and hotel stays by providing comparative pricing from numerous service companies. The company uses Keynote Transaction Perspective and KITE to test the performance of its home page and a range of transactions customers typically perform, such as searching for a hotel room or a flight on priceline.com as well as on Booking.com, Agoda.com and other members of the priceline family of companies.

"Our customers’ connected and mobile Web applications are becoming increasingly mission-critical. The experience of priceline.com demonstrates that Keynote provides customers with the most accurate and comprehensive monitoring services and measurement data regarding Web application performance and availability from the end user perspective,” said Anshu Agarwal, vice president of marketing at Keynote.

Agarwal continued, "We are the industry’s market leading stand-alone provider of on-demand testing, measurement and monitoring services of online experience from the end-user perspective. We have a singular focus at Keynote which is to help our customers become ‘the best of the best’ in quality of experience of their connected and mobile Web sites. There is true value in that market position and Keynote customers experience it every day.”
