Microsoft Advertising Selects Criteo as Preferred Partner for Personalised Retargeting Across Europe

Criteo to Provide Enhanced Ad Relevance to the Microsoft Media Network

LONDON, March 10, 2011 - Criteo (www.criteo.com/), the global leader in personalised
retargeting (www.criteo.com/us/retargeting), and Microsoft Advertising
today announced their partnership across Europe, to allow Microsoft
Advertising to implement Criteo's retargeting solution on its European
premium display advertising network Microsoft Media Network (MMN). This deal
will add value to each of the over 1000 top retailers implementing Criteo's
retargeting solution today, as well as the more than 300 quality partner
sites on MMN reaching up to 144 million European users a month[1]. As a
result of the successful existing relationship in individual European markets
over the last two years, with Criteo being one of Microsoft's most important
customers on the Microsoft Media Network, this partnership will now be rolled
out across the region. As part of the agreement Microsoft will deepen
Criteo's technical integration so as to further increase the volume of
business that both companies do together.

Microsoft Advertising selected Criteo following an extensive industry
evaluation based on key technology and industry criteria, including: value
proposition to advertisers; quality and growth of clientele; creative
capabilities; volume of impressions at competitive CPMs; and emphasis on
consumer privacy and publisher data protection.

"Criteo looks forward to further strengthening the relationship with
Microsoft Advertising as a result of this new partnership. Microsoft
Advertising's combination of scale and quality publisher sites across Europe
is an ideal partner for our advertisers, and we are excited to do more
together" said Jonathan Wolf, Criteo's chief business development officer.
"Microsoft has long been an innovator in online advertising, and has been a
core partner for Criteo as we have grown over the last few years in Europe.
We have always been delighted by the reach and performance of the high
quality inventory on their Microsoft Media Network. We see that this
partnership strengthens Microsoft's digital advertising solution, and we are
delighted to be delivering ever more relevant advertising to their millions
of users."

"We are continually dedicated to deepening the value of our premium
advertising network, and continue to set industry expectations about digital
advertising and advertiser ROI including audience targeting solutions," said
Laurent Delaporte, VP of Microsoft Advertising EMEA. "Expanding the presence
of Criteo's high quality personalised ads across the Microsoft Media Network
adds significant value to advertisers and consumers alike, and catalyses
momentum for digital advertising technologies. This is a win-win partnership
for all parties involved."
