The
study
examined
data
from
two
of
the
UK’s
busiest
ecommerce
websites,
ASDA
and
William
Hill.
Given
that
more
than
half
of
all
page
impressions
on
these
sites
are
from
logged-‐in
users,
they
provided
a
robust
sample
to
compare
IP-‐based
and
cookie-‐based
analysis
against.
The
results
were
staggering,
for
example
an
IP-‐based
approach
overes3mated
visitors
by
up
to
7.6
3mes
whilst
a
cookie-‐based
approach
overes.mated
visitors
by
up
to
2.3
.mes.

“The
principle
of
garbage

applies
here.
[…]
what
makes
a
behaviour
targe<ng

<ck,
and
produce
results,
is
not
its
intelligence,
it
is
your
ability
to
actually
feed
it
the
right
content
which
it
can
then
target
[…].
You
feed
your
BT

crap
and
it
will
quickly
and
efficiently
target
crap
to
your
customers.
Faster
then
you
could
ever
have
yourself.”
