Look Voyages Boosts Customer Engagement and Drives up Conversion Rates With Autonomy Optimost

Leading French Holidays Provider Embraces Meaning Based Marketing to Deliver Compelling Online Experience and Convert Browsers into Buyers

CAMBRIDGE, England and SAN FRANCISCO, June 1, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that Look Voyages
is using Autonomy Optimost's award-winning Multivariable Testing (MVT)
solution to boost customer engagement and retention and drive up conversion
rates on its website, www.look-voyages.fr, which receives up to two
million unique visits each month. Autonomy Optimost offers the industry's
most advanced, meaning-based analysis, multivariable testing and marketing
optimization solutions for driving meaningful business decisions,
streamlining business operations and maximizing overall revenue. Autonomy
Optimost enables Look Voyages to test virtually limitless permutations of web
content and layout including text, pictures, video, page layout, and banners
to determine the winning combination and cost-efficiently optimize the
bottom-line performance of its website. Look Voyages is the third largest
provider of package holidays in France and a subsidiary of global tour
operator Transat.

Unlike legacy marketing approaches which rely on ill-defined metrics or
pure guesswork to gauge customer preferences and intent, Autonomy Optimost
performs tests in real-time and with actual online customers to reveal the
configurations that encourage conversions on the various landing pages, web
forms, shopping cart pages and banner ads. In today's highly competitive
market, the ability to gain an understanding of customer insights and
purchasing behaviour is essential for creating an online experience that is
compelling, meaningful and rewarding in order to boost customer engagement
and conversion rates.

As a means to uncover the combination of web content and layout that
visitors find most compelling, Look Voyages selected Autonomy Optimost's
award-winning MVT technology, which presents distinct holiday seekers with
different versions of the www.look-voyages.fr website enabling the
marketing team to instantly identify what layout and content combinations are
most likely to convert visitors into buyers. Thanks to Autonomy Optimost's
intelligent solution, Look Voyages has experienced a dramatic and measurable
improvement in its online business, including increases in online sales,
clickthroughs, registrations, and page views.

"After only a few weeks of testing, we were able to identify the exact
content and layout that drive up customer engagement and retention rates,"
said Damien Poulain, eCommerce & B2C Manager at Look Voyages. "Changes which
on the surface would seem quite minimal and inconsequential, such as the
change of a color or the location of a button or the background color of the
promotion page, can make a significant difference. Autonomy Optimost's
solution has provided us with invaluable information to help us improve the
experience delivered to our customers. Furthermore, we have been able to take
web design out of the IT office and into the playing field, where customers
have revealed to us, by voting with their clicks, the website content and
layout that most closely matches their preferences."

"While investing in traffic acquisition may bring customers to your site,
getting visitors to take action once they are there remains a big challenge
for online retailers," said Greg Kelton, VP EMEA Autonomy Optimost.
"Uncovering and acting on the content on your website that is motivating
visitors to convert is therefore essential for monetizing traffic acquisition
investments. Look Voyages became convinced of how invaluable this information
is to its business once it saw the dramatic increase in conversion rates as a
result of deploying Autonomy Optimost."
