Dear Ben Kruger,
The most conservative estimations on how many users have cookies
enabled come from university and research sites. These are naturally
also the most trust-worthy statistics:
"90% of users have cookies enabled permanently on their browsers"
(SOURCE: School of Information and Computer Science, University of
California, Irvine, "Modeling the Internet and the Web: Modeling and
Understanding Human Behavior on the Web", Power Point Presentation -
requires Power Point ,
<http://ibook.ics.uci.edu/Slides/MIW%20Chapter%207.ppt> p. 14).
A researcher from Slovenia, also estimates that " Users can block or
delete cookies but it is estimated that well over 90% of users have
cookies
enabled.", (SOURCE: Miha Grcar, "USER PROFILING: WEB USAGE MINING",
Department of Knowledge Technologies, Jozef Stefan Institute
<http://eprints.pascal-network.org/archive/00000741/01/MihaGrcar-WebUsageMining.pdf>);
Grcar is basing himself on :
P. Baldi, P. Frasconi, P. Smyth. Modelling the Internet and the Web.
pp. 171?209. ISBN: 0-470-84906-1. 2003.
Of course, although these rates are already high, advertisers are
bending the information higher. Just for example, though this is
biased information and therefore cannot be seriously regarded:
"What happens if a customer does not have cookies turned on in their browser?
Our research indicates that nearly 97% of internet users have cookies
enabled on their browser. "
(SOURCE: Uniqupaid.com, <http://www.uniqpaid.com/advertisers/faq.shtml>).
I hope this answered your question. Please contact me if you need any
clarification on this answer before you rate it. Search strategy was:
"of internet users have cookies enabled" or
"of users have cookies enabled" |
