Online Shoppers Browsing at Home, Buying at Work

In the U.K., 29.1 million people age 15 and over visited an online retail site
from a home or work location in May 2009, representing 79 percent of the total
U.K. online population. Approximately three quarters of the total visits, time
spent, and pages viewed in the online retail category were made from home
locations, with the remaining quarter occurring at work computers.

Interestingly, visitors from work computers were slightly more likely to
purchase goods online than those accessing retail sites from home computers.
While representing only 25 percent of total visits to the online retail
category, workplace visitors accounted for 36 percent of online retail
transactions and 35 percent of money spent at online retail sites, based on a
five-month average ending May 2009.

Although online shoppers visit retail sites about three times more frequently
at home than they do at work, they only spend twice as much at home, said Mike
Read, SVP and managing director, comScore Europe. That online shoppers are
relatively more likely to make a purchase at work is not entirely surprising. In
fact, we often see that people have very different browsing patterns between the
two locations, having a tendency to be task-oriented and transaction-minded at
work and more leisurely when browsing at home. By understanding such
differences, online retailers can better optimize their online marketing and
advertising strategies to reach consumers when they are closer to the point of
purchase.

Amazon is U.K.’s Most Visited Online Retail Destination from Home and
Work

Amazon Sites was the most visited retail property in the U.K., receiving a
total of 49.4 million visits in May 2009. Apple.com Worldwide Sites ranked
second with 27 million visits, followed by Home Retail Group (16.1 million
visits) and Tesco Stores (13.1 million visits). Apple.com, the U.K.’s
second most visited online retail site, drew only 13 percent of its total visits
from work locations, while NEXT Group attracted 35 percent of total visits from
work locations, a higher proportion than any other top 10 retailer.
