SAN MATEO, Calif. -- July 27, 2012

Keynote Competitive Research, the industry analysis group of Keynote® (NASDAQ:
KEYN), today announced that in honor of the London 2012 Games it will hold its
own International Summer Games for Mobile Retailers. Beginning next week
Keynote will publicly announce the top three performing mobile retail websites
from around the world based on its ‘Keynote Mobile Retail Index – World
Edition,’ an index assessing the download speed and reliability of leading
mobile retail sites as measured on smartphones from different countries around
the world.

The company will name Gold, Silver and Bronze winners based on the top scoring
sites on the index each week. The index score is a combination of each site’s
average speed and reliability as measured 24 x 7 over the previous seven days.
Reporters and analysts wishing to receive the names of the winning mobile
retail websites each Tuesday over the next three weeks should email Dan
Berkowitz at dberkowitz@keynote.com and request receipt of the latest results.

The Keynote Mobile Retail Index - World Edition shows the average response
times, success rates and a composite score for downloading the homepage of
selected sites of retailers using Mobile Web Perspective® over Air. Keynote
repeatedly tests the sites in the index hourly and around the clock over two
Tier 1 wireless networks in each country (Australia, France, Germany, Japan,
Sweden, UK and US) over popular smartphones. The retail sites that appear in
the Index were selected to provide an industry benchmark for well-known
company sites.

“Mobile technology will be put to the test during the London 2012 Games.
Keynote’s ongoing research regarding consumer satisfaction levels for
accessing Web content over smartphones and tablets shows that much work still
remains to be done, not only by retailers, but by companies in many important
industries,” said Ren Bloom, vice president of marketing at Keynote. “We
believe the London 2012 Games is an ideal time to shine a competitive light on
mobile retail; one of the fastest growing and most important industry sectors
benefiting from the consumer move to mobile, yet still experiencing
significant performance pains.”
