Is Your Website Accessible for
the Visually Impaired?
Don't Unwittingly Exclude Visitors to
Your Site.
Paul Smithson - 22nd December 2008
The Internet can be a difficult place to
navigate if you’re visually impaired and it has to be said that
far too many webmasters don’t make much effort to ensure that
browsing their site is as easy as it could be for visually
impaired visitors. Fortunately, making your site more
accessible isn’t all that difficult or
time-consuming.
One of the most basic and yet important
things you can do to improve your site’s accessibility is to
name links properly. Naming a link “click here” may work fine
for sighted people, but it’s not going to make much sense to
someone who is visually
impaired.
A link should be descriptive, such as
“Click here to download 1,001 cat food recipes.” This
also allows you to work keywords into your link text, which has
a knock-on benefit for search engine
optimization.
The next major thing you can do to improve
your site’s accessibility is to include alt text for every
image on your site. If you have a photo of a dress your
site is selling don’t have alt text that says picture01.jpg as
that means absolutely nothing to someone who is visually
impaired. Instead use something along the lines of “Image of
blue sun-dress with white floral
print.”
This is also another important SEO
technique, so it’s something you should be doing anyway.
Include keywords when possible, but make sure you describe the
image as thoroughly as possible for your visually impaired
users at the same time.
This is especially important if your image
needs to be clicked. If you have a photo of a dress, and
they can click the photo to order it, you should make the alt
text something along the lines of “Click here to order the blue
sun-dress with white floral print.” This is incredibly
important. Often webmasters will use graphical order buttons
and not realize that if the ALT text says ‘Image001.jpg’ any
visually impaired users won’t have a clue that they need to
click on that image to order.
Another important technique for making your
site accessible to visually impaired users is to use relative
font sizes, instead of using absolute font sizes. Although this
may make your site look a little odd at times, it will go a
long way toward making your site accessible to the visually
impaired. If a user who can’t see well visits your site,
they can change the font size through their browser so they can
see the words better.
Don’t count on things like color, bold, and
symbols to explain things. For example, if you have a
form on your site and certain fields are required, be sure to
put “(required)” beside the fields rather than making the text
red, or putting an asterisk beside the field. The
visually impaired user won’t be able to see these things, so
it’s important to actually use text to prompt them for required
fields.
If your site uses a lot of Flash or image
maps, you could go that extra step and make a special page
devoted to the visually impaired. You should offer a
clear link to this version, so it will be easy to
find.
Since Flash is often difficult to navigate
for the visually impaired, it’s very important to offer a
non-Flash version of your site. Also, many visitors
simply don’t like Flash-based websites. These visitors,
whether visually impaired or not, will appreciate having an
alternate version of your site.
Finally, there are also validators
available that can check your site for accessibility. You can
run your site through one of these to ensure compliance with
accessibility standards. XSitePro has this feature built into
the “Page Analysis” section so that you can check each of your
pages against best-practice and make the changes necessary to
make sure that the page meets the needs of visually impaired
users.
At the moment making your site accessible
to visually impaired users is optional in many countries, but
it is already a legal requirement in others and it is likely to
become increasingly important to comply with approved standards
as the Internet becomes an essential part of everyday
communications, and rightly so in my opinion. Just because
someone is visually impaired shouldn’t mean they are denied
access to information. And by making some of the tweaks
mentioned above can make all the difference and make your site
accessible to a whole new
audience.
