Alimama Allows China's Web Publishers and Advertisers to
Trade Online Advertising Inventory

Localized Business Model Designed for China Market


    HANGZHOU, China, Nov. 20 /Xinhua-PRNewswire/ -- Alibaba
Group, a global e-commerce leader and the largest e-commerce
company in China, today announced the official launch of
Alimama ( http://www.alimama.com ), an online advertising
exchange which allows web publishers and advertisers to
trade online advertising inventory.  A wholly owned
subsidiary of Alibaba Group, Alimama has emerged from its
100-day beta period as China's largest online advertising
exchange platform and well positioned to help small- and
medium- sized web publishers monetize the estimated 80% of
web site traffic which goes unmonetized in China.

    Since launching the beta version of the marketplace on
August 10, Alimama has already signed up more than 150,000
small- and medium- sized web publishers and 135,000
personal blogs, covering more than 1 billion page views per
day.  The exchange has over one million registered users
with an inventory of more than 380,000 advertisement
positions available for purchase, with transactions for
more than 20,000 advertisement positions occurring each
day.  Alimama continues to grow at a rapid rate, adding
4,000 small and medium sized websites and 10,000 personal
blogs each day.

    Alimama is the newest innovation to come to market from
the Alibaba Group, applying the Group's expertise in
operating online marketplaces to the trading of internet
advertising inventory.  Building on Alibaba Group's strong
track record in pioneering e-commerce communities among
China's highly fragmented small- and medium- sized
businesses, Alimama's growth is expected to encourage the
growth of the Alibaba Group's five other wholly-owned
subsidiaries which operate in distinct, but complementary
areas of e-commerce.

    Alimama's unique business model is designed to meet the
needs of China's fragmented market for online advertising,
providing a system that is transparent to both web
publishers and advertisers.  To use the service, publishers
register on Alimama.com to provide a description of the
advertising inventory for sale, as well as the pricing
models based on which the inventory can be sold, such as
pricing based on impressions served, clicks or other
actions by Internet users.  Advertisers review the
information posted by publishers, along with independent
website traffic data.  Once they've decided to buy the
inventory, they simply click "Purchase" and
follow the steps to upload their ad.  Current advertisers
include large companies such as Bank of China and small
advertisers, such as restaurants and shops.

    "No longer will 80% of China's website traffic go
unmonetized," said Jin Jianhang, an Alibaba Group
spokesperson.  "The launch of Alimama makes web
publishing commercially viable for China's more than one
million small- and medium-sized web sites.  At the same
time, advertisers now have an affordable way to reach
targeted audience groups on the growing number of
specialized websites and blogs in China."
