Below are gathered case study summaries from multiple authoritative
sources and are based on numerous research projects:
The benefits of good web design

experience improvements yielded more than $60.
IBM's website, the most popular feature was the search function,
because the site was difficult to navigate. The second most popular
feature was the 'help' button, because the search technology was
so ineffective. IBM's solution was a 10-week effort to redesign
the site, which involved more than 100 employees at a cost estimated
'in the millions.' The result: In the first week after the redesign,
use of the 'help' button decreased 84 per cent, while sales increased
400 per cent.
Box, June 2000. It's quite normal for e-commerce sites to increase
sales by 100% or more as a result of usability, but configurator-driven
sites can probably increase sales by at least 500% by emphasizing

The cost of bad web design
customer experiences will have a devastating effect on holiday

20 major sites audited, 51 per cent werecompliant with simple
web usability principles such as "is the site organized by
user goals?" and "does a search list retrievals in order
of relevance?" (in other words, the average site violated
half of these simple design principles).
sites will waste between $1.5M and $2.1M on redesigns next year
(1999). Why? Designers are engaged in an endless cycle of overhauls
that don't fix their problems. Their goals of achieving fast performance
and consistent look and feel are directionally correct but miss
out on at least 20 other more specific usability objectives. And
since ease of use is not measured, flaws go undetected.
