ARE THE WORLD’S TOP ECOMMERCE SITES
FAST ENOUGH FOR ONLINE SHOPPERS?
When websites are slow, every business metric suffers – from
page views and bounce rate to conversions and revenue.
Shoppers expect a speedy online experience, yet the average
ecommerce site doesn’t meet this demand. The culprits: bloated,
complex pages that take too long to render.
INTERNET USERS ARE INCREASINGLY DEMANDING
In 1999, the average user was willing to wait 8 seconds for a page to load. By 2010, 57%
of online shoppers said they would abandon a page after 3 seconds.
WHICH SITES WERE FASTEST?
Among the top 100 ecommerce sites, these were the fastest home pages.
THE PERFORMANCE CULPRITS: PAGE SIZE AND COMPLEXITY
Page size and complexity typically
correlate to slower load times. The
median top 100 page is 1354 KB
in size and contains 108 resource
requests (e.g. images, HTML, third-
party scripts).
PERFORMANCE
METRICS DEFINED
Time to Interact (TTI)
The point at which
primary page content
renders and becomes
interactive (e.g., feature
banners with functional
call-to-action buttons).
Load Time
The point at which all of
a page’s resources –
from images to third-party
scripts – have downloaded
and rendered.
TOP ECOMMERCE PAGES TODAY
DON’T MEET USER EXPECTATIONS
The median Time to Interact (TTI) for a top 100
retail website is 5.2 seconds. Only 14% of the top
100 retail sites rendered feature content in fewer
than 3 seconds. 9% of the top 100 pages took 10
seconds or longer to become interactive.

There are compelling reasons why companies – particularly
online retailers – should care about serving faster pages. In a
world where every second counts, are you helping or hurting
user experience – and ultimately your own bottom line? Three
seconds is all it takes for visitors to abandon a page if not loaded
quickly enough. Whether your goal is to convert browsers into
buyers or ensure that content is served to as many as possible,
your eye should be on this 3-second target.

MANY SITES FAIL TO OPTIMIZE IMAGES
Despite the fact that images
comprise 50 to 60% of the
average page’s total weight, 43%
of the top 100 sites failed to
implement image compression,
a core optimization technique.
TAKE CHARGE OF YOUR WEBSITE’S PERFORMANCE
There are opportunities for every site — even those that are relatively fast
already — to fine-tune performance by taking a more aggressive approach to
front-end optimization. Find out more: www.radware.com/Products/FastView/.
