TripAdvisor Becomes the First Travel Brand to Break the 40 Million Unique Monthly Visitors Barrier

Traffic to World's Largest Travel Site Up 60 Percent From Beginning of Year

LONDON, September 23, 2010 - TripAdvisor(R), already the world's largest travel site*, celebrates
becoming the first travel brand to have more than 40 million unique visitors
in one month.

TripAdvisor has experienced tremendous growth in site traffic, with more
than 40 million unique monthly visitors, according to comScore Media Metrix
July worldwide numbers for TripAdvisor sites, up 60 percent from the
beginning of the year. TripAdvisor additionally features 20 million
registered members, up from 15 million in January 2010.

TripAdvisor is now available in 14 languages, across 23 countries
worldwide. In 2010 alone, TripAdvisor has launched new websites in eight
markets globally - Turkey, Denmark, Mexico, Poland, Norway, Australia,
Singapore and Thailand.

"We are excited that TripAdvisor continues our aggressive growth
globally, to help new audiences around the world plan and experience the
perfect trip," said Steve Kaufer, founder and CEO of TripAdvisor. "We have
always believed that user generated content would greatly benefit the travel
community and are delighted that this belief has been demonstrated with the
site becoming the first in the travel arena to break the 40 million monthly
user barrier."

To put TripAdvisor's popularity into context for the UK market, the
TripAdvisor.co.uk site on its own boasts 4.5 million unique visitors per
month. That's more than Expedia.co.uk (3.4mm), HSBC.co.uk (4.1mm), and on a
par with BT.com (4.5mm)*.

"The tremendous reception of our site, created by travellers for
travellers, underscores the universal appeal of TripAdvisor as the go-to
source for travel reviews and planning," concluded Kaufer.
