Also,
they had similar pages that displayed pictures of all the items within a given
category. We call these pages product galleries. While the number of items and
the specific information that was presented with each product image varied, all
of the sites had basically the same galleries.
What was different were the pages between the home page and the galleries.
We call these "department pages", because they represent what's sold in a specific
store's departments. For these sites, "departments" were categories such as women's
swimwear or table linen.
Among the thirteen sites we studied, we found five different department-page
designs. Most listed the departments in a left navigation panel, with the galleries
for that department listed in the center. (Look at Macy's department pages --
http://www.macys.com -- by clicking on Women,
then Tops.)
However, some got clever. For example, the Gap and Victoria's Secret (http://www.gap.com,
http://www.victoriassecret.com) both
used a menu based department that wasn't a separate page, but instead used menus
at the top of the screen.
Old Navy (http://www.oldnavy.com) used
a combination department and gallery page where sometimes the left nav contains
galleries and sometimes it contains products. (Try clicking on Girls, then Accessories.
Compare that to clicking on Girls, then Skirts & Dresses.)
Lands' End (http://www.landsend.com)
used a design that had both product descriptions and departments. (Click on Women's,
then Swimwear to see their department page design.)
Finally, Eddie Bauer (http://www.eddiebauer.com)
combined text lists of all the products in the department with a toggle to see
the pictures for a gallery. (Click on Women, then Sweaters. Click on View Photos
to see a specific gallery.)
After realizing that there were five basic types, we got very excited about
seeing if the different types made a difference. While we'd expect differences
between individual sites, it wasn't clear that we'd see if an entire type of design
outperformed others.
After watching people shopping on the sites, we compared their behaviors. (As
with many of our e-commerce studies, these users came to our facilities with a
list of products they wanted to buy. We gave them the money to make the purchases
and told them to purchase as much on their list as possible. In this particular
study, there were 44 users who shopped for a total of 687 products.)
Studying the different designs on apparel and home goods sites turned out to
be a good thing. Out of the 687 shopping expeditions that we observed, users only
used the search engine 22% of the time. That means that 78% of the time they used
the categorization scheme to locate their desired products.
We found the sites with the standard left-nav design, such as Macy's, actually
performed the worst, selling the least amount of product. Lands' End's design
performed the best, with Old Navy's combination design being second.
It turned out, in our study, that the number of pages that a user visited before
they put something into their cart was inversely proportional to purchasing. The
more pages they visited, the less they bought. (Remember, our users knew exactly
what they wanted and were ready to make a purchase.)
When you look at the number of pages visited before a user put something into
their cart, users who traveled through Lands' End's design purchased by visiting
half the pages than users through Macy's design. Lands' End's design had fewer
visits to "wrong galleries" -- galleries that didn't contain the user's desired
content (often forcing the user to hit the "back" button -- a clear sign of a
problem).
If you compare Lands' End's design to Macy's, you see some interesting differences.
By just looking at Macy's ' "Women's Tops" department to Lands' End's "Women's
Sweaters", you can see that Lands' End goes to great length to let people have
information they need to make a decision. They give categories, such as "Twinsets",
"Cardigans", and "Cashmere".
Whereas Macy's just lists "Sweaters". Visiting the sweaters gallery shows every
sweater Macy's sells, with no distinction between the types of sweaters or fabrics
used. Users have to look at each sweater to determine if it's what they are interested
in.
With the Lands' End design, users could either go straight to a product that
was of interest to them or look at the category's gallery by clicking on a "View
these and more" link. While a lot of our users clicked on products, many viewed
the gallery before choosing their product.
The Lands' End design can serve as a model for other types of content. We could
see job listing databases, news stories, or other large content repositories using
a similar design. An example of a page that was changed to this type of model
is the In Focus page on the A.G. Edwards site. The old style simply lists a bunch
of vertical links. The current style categorizes these and also includes links
to the galleries.
Another example of a page that might be able to benefit from this type of layout
is the air conditioning page on the doityourself.com site.
The pictures on Lands' End's department page were helpful sometimes and ignorable
the rest. Seeing a picture of a "twinset" helps identify what it is, whereas the
pictures of "Fine Gauge Cotton" and regular "Cotton" could be swapped and nobody
would probably notice or care (except Lands' End's buyers). This means that content
that doesn't lend itself to pictures (such as diseases) doesn't really need them
-- it's not a necessary part of this specific design.
As we study the differences in the designs of these department pages, we can
learn more about how to design information displays that are more effective to
getting users to their desired content.
