The
Print-to-Web Evolution and the Importance of Usability
Until
recently, the primary way to share information with the masses was
to publish it in magazines, newspapers, and newsletters or to broadcast
it over the radio or on television. Even a couple of years ago, most
printed publications were not available online, though perhaps a contact
from whom a printed copy could be obtained might have been offered
online. As bandwidth and Internet usage has increased, more and more
publications became available online as well as in print.
More recently, we are seeing publications whose primary medium of
distribution is the Web and for which print versions are secondary
or maybe even non-existent. Increasingly, people are making the Internet
their first stop to seek information, and that is encouraging many
publishers to go "Web first" or "Web only." Of
course, these Web publishers are also influenced by the relative ease,
speed, and cost-effectiveness of getting the information "out
there" online. Not only can information in its original form
be more quickly and less expensively disseminated via the Internet,
but additions, changes, and updates are relatively easy to make on
the Web and are practically impossible to do in a timely or inexpensive
way in hardcopy publishing.
The tragic events of Sept. 11 provide a good example. On that day,
many Americans went to the Internet to find the latest news about
the attacks. They were seeking quick and up-to-date news about the
crashes, the victims, the government's reaction, and so forth. Many
of the news sites found that the high volume of Internet traffic was
more than their servers could handle; many sites were inaccessible
during the first few hours after the attacks. News sites had to be
modified quickly to provide information to the public in the most
rapid and concise manner. This meant removing many graphics, photographs,
and video clips to slim down the size of their files so that downloading
time could be reduced. Within hours, sites were better able to accommodate
the increased traffic.
About five years ago, the only "web" that most Americans
were familiar with was a spider web or the web of a baseball mitt;
however, today, about 150 million Americans use the Internet and the
World Wide Web. Studies and industry experts state that data traffic
carried by network service providers has increased 30 percent to 40
percent over the past year (Interactive Week, Sept. 24, 2001). This
rapid increase has led to more problems with congestion during times
of high traffic during an average day.
We
are now finding that the print-to-Web evolution is more than simply
providing information online; it is the changing way that information
is presented. Information on the Internet cannot be presented in the
same manner as in print.
As a result of new and growing technology, our attention spans appear
to have shrunk significantly, especially when it comes to the Internet.
Research has shown that users often will not continue to navigate
through a site if the time to move from one page to another within
the site is more than one second (Nielsen). Slow downloading often
lowers the level of trust the user has in the site and ultimately
can cause lost traffic as users gravitate to faster sites. Sites must
be user-friendly to capture visitors and to keep them.
So, what's all this got to do with you? Most of the readers of Public
Roads are responsible for providing some content to some Web site.
If you want your content to be read, you need to do your part to make
sure that it is useable. Usability includes many aspects of design,
including the way content is written, navigation, graphics, and the
overall speed of the site. According to Designing Web Usability by
Jakob Nielsen, highly regarded as one of the leading experts on Web
usability, there are three main guidelines for writing for the Web:
-
Be succinct. Write no more than 50 percent of the text you would have
used to cover the same material in a print publication.
- Write for scannability. Don't require users to read long
continuous blocks of text; instead, use short paragraphs, subheadings,
and bulleted lists.
- Use hypertext to split up long information into multiple
pages.
