Ten Good Deeds in Web Design
When analyzing Web design, it is easy to
identify a large number of mistakes that reduce usability:
It is much harder to say what good things to
do since I have never seen a website that was truly stellar with respect to
usability. The best major site was probably amazon.com as of late 1998, but
during 1999 Amazon declined in usability due to the strategy of blurring the
site's focus.
Of course, articles that list 30 mistakes can be seen as constructive
criticism and a prescription for 30 things to do in a Web project: design to
avoid each of the mistakes!
Here's a list of ten additional design elements that will increase the
usability of virtually all sites:
- Place your name and logo on every page and make the logo
a link to the home page (except on the home page itself, where the logo should
not be a link: never have a link that points right back to the current page).
- Provide search if
the site has more than 100 pages.
- Write straightforward and simple headlines and page
titles that clearly explain what the page is about and that will
make sense when read out-of-context in a search engine results listing.
- Structure the page to facilitate scanning and help users
ignore large chunks of the page in a single glance: for example, use grouping
and subheadings to break a long list into several smaller units.
- Instead of cramming everything about a product or topic into a single,
infinite page, use hypertext to structure the content space
into a starting page that provides an overview and several secondary pages
that each focus on a specific topic. The goal is to allow users to avoid
wasting time on those subtopics that don't concern them.
- Use product photos, but avoid cluttered and bloated
product family pages with lots of photos. Instead have a small photo on each
of the individual product pages and link the photo to one or more bigger ones
that show as much detail as users need. This varies depending on type of
product. Some products may even need zoomable or rotatable photos, but reserve
all such advanced features for the secondary pages. The primary product page
must be fast and should be limited to a thumbnail shot.
- Use relevance-enhanced image reduction
when preparing small photos and images: instead of simply resizing the
original image to a tiny and unreadable thumbnail, zoom in on the most
relevant detail and use a combination of cropping and resizing.
- Use link
titles to provide users with a preview of where each link will
take them, before they have clicked on it.
- Ensure that all important pages are accessible for users
with disabilities, especially blind users.
- Do the same as everybody else: if most big websites do
something in a certain way, then follow along since users will expect things
to work the same on your site. Remember Jakob's Law of the Web User
Experience: users spend most of their time on other sites,
so that's where they form their expectations for how the Web works.
Finally, always test your design with
real users as a reality check. People do things in odd and unexpected ways, so
even the most carefully planned project will learn from usability testing.
