Going Quantitative
Ok, testing web sites with users in the lab (we're talking usability testing) is the gold standard. You can't live without
it. You get that.
But there's a problem. Observational research in the lab means small sample sizes.
And small sample sizes means it's hard to generalize about some important things,
like users' opinions. Opinions need big samples.
Enter Kantuit Online. Why are opinions about web sites important?
Some usability purists need reminding that knowing users' opinions is critical.
You want to know what content users might give priority for example. You want to
know what features users value. You want to know what users might want to do
vs. what they actually do (which is what usability testing and observational research
is all about).
Why Not Just Do an Online Survey?
Most online survey tools make it easy to create survey questions and get responses
online. This is what makes them "online surveys". But just because you can create
them online and get responses online, does't mean they are good for testing
things that are online (i.e. web sites).
On the contrary, most online survey tools are designed to make it easy to collect
data on just about everything, from opinions about the president, to opinions
about a new potato chip bag design.
The way we do online research (that is research about web sites) is
very different. Most online surveys lack at least three key ingredients
we have.
- The ability to show users the proper stimulus (that is the ability
to show users a real web page)
- The ability to let users answer questions before, during, and after, they
interact with a real web site
- The ability to track the clickstream of the user while he interacts
with the web site (or sites) we're testing
All of this requires some fancy technology that has been developed precisely to
test web sites. The point of it all is to connect user opinions with behavior in
meaningful ways.
Getting the Stimulus Right
What's so bad about asking users to prioritze features or content without showing
them things?
It all has to do with memory. Not RAM. Human memory. Someone calls to ask you about
real estate web sites. Last week you visited sites looking at houses. The interviewer
ticks off a list of features that real estate web sites have and asks you to prioritize
them on a scale of 1 to 5.
Such questions assume that you know and remember what each item on the list actually
is—something that is unlikely for a signficant number of people.
Although you can still produce cool charts and graphs from surveys that collect
data this way, even though you might have a decent margin of error and so on, it's
basically garbage in garbage out.
What about Just Showing People an Image of a Web Page?
Showing an image of a web page and asking people to respond to it is better than
nothing. At least people can look at what you're asking them to respond to. And
sometimes we resort to this technique when there isn't a site to interact with,
because it's an early-stage prototype, or because it is a screenshot from a web
site that we can't let people interact with for other reasons.
But the problem with most online survey tools is that they don't show screenshots
of web pages very well. Most have a limit on the size of the image that can be shown,
or present other challenges for getting feedback on full page screenshots, all because
they are designed for testing shampoo bottle designs (and everything else) and not
web sites.
What do You Mean by "Connect Opinion with Behavior"?
It's a well known research phenomenon. People often answer survey questions in the
way they think they should or the way they think the interviewer wants them to.
In real life, people often say one thing and actually do another. How do you ensure
your users really mean what they say?
It's all about asking the right questions in the right way at the right time. By
way of example, here's what we recently did in a survey for the healthcare industry.
In healthcare, everyone is trying to get people to do stuff after using a web
site: talk to their doctor, choose a hospital, live a healthier life,
and so on.
We wanted to measure the effectiveness of hospital quality information on decision
making. Would people be more likely to choose a hospital for lower back surgery
after seeing information about the quality of the hospitals in their area?
Using Kantuit Online, we showed people three web sites (a non-profit, a government
site, and a health insurance site) that allow you to search for hospitals in your
area, providing quality scores on each across a range of criteria.
What we found was that people didn't understand hospital quality search results.
Only about half the time were people able to say which hospital had the best outpatient
experience for lower back surgery (even though all the sites provided an answer).
People reported they would use the results of a hospital quality search in roughly
the same ratio (about half the time).
The government and health insurance sites did slightly worse than the non-profit.
But when only half your users understand something, you've got a big problem on
your hands.
Looking for evidence that people say one thing and do another? In another part of
our healthcare research we found that, when asked, people said they felt they were
effective finding cause and treatment information for lower back pain about 80%
of the time. In reality (since we tracked their clickstreams) people only found
the information about half the time.

Ok, How Much Does It Cost?
The costs for Kantuit Online surveys tend to be higher than traditional online surveys,
with a typical project coming in at around $25-40k. You knew there was a gotcha!
But for many enterprises these types of surveys have become an indespensible tool
for site development, monitoring and enhancement.
But the gotcha really isn't one when you think about it, since as we've said, in
most cases doing a traditional survey about a web site is at best money down a hole,
and at worst, going to give you bad data which could result in bad decisions. Don't
let it happen to you!
