Criteo Drives Record Growth and Propels Client Revenue Through 2010

Global PPC Retargeting Company Advances Leadership Position

LONDON, January 12, 2011 - Throughout 2010, Criteo, the global leader in pay-per-click (PPC)
retargeting, gained worldwide market leadership through innovative
advancements to its advertising technology and expanding globally to service
over 16 countries across Europe, North America and Asia. With this success
and momentum, the company catalysed record-setting e-commerce display
advertising conversion rates and revenue.

Globally, Criteo continues to grow as its personalised retargeting
technology gains international recognition. Throughout the past year, Criteo
served more than 50 billion ads, and experienced a:

    - Tripled (3x) client base, to over 1000 top e-commerce clients

    - 8x increase in ad impressions served

    - 10x increase in ad clicks

    - 11x increase in sales generated post-click

In the UK, post-click sales increased by 600 per cent, cementing Criteo's
place as market leader in personalised retargeting. Criteo now partners with
more than 200 well known UK advertisers who benefit from the advanced
technology.

"Major UK media agencies are forecasting for stronger growth in display
ad-spend compared to search - with most predicting a 12-13 per cent increase
in 2011. A key driver of this has been the re-assessment by advertisers that
display can now deliver a performance-based marketing channel with the added
benefit of branding. Personalised retargeting has played a significant role
in this shift as it affords a fully transparent and accountable channel
whilst delivering ROI comparable to search through highly relevant creative.
We fully expect this trend to accelerate in 2011." Michael Steckler, MD
Northern Europe.

Leadership and Innovation

Throughout 2010, Criteo solidified its industry leadership by announcing
its Advisory Board of e-commerce and online advertising veterans, and
securing $US7 million Series C round of funding from Bessemer Venture
Partners. Additionally, Criteo recently unveiled the Performance Optimisation
Platform, which for the first time allowed advertisers and agencies to define
and manage their retargeting campaign in real-time, down to the category
level. The platform's industry-first self-service CPC management capabilities
drive unprecedented ROI via a real-time automated bidding interface and
product-specific campaign management. This innovation has enabled Criteo to
become the go-to partner for e-commerce merchants that are seeking to
cost-effectively win back lost prospects and drive increased loyalty from
existing customers.
