Preparing Effective Content Make Content Accessible
In order to make your content accessible you must
- use good keywords to support search engins
- write for international users
- plan for users with disabilities
Use Good Keywords
Keywords help search engines find your site by explaining what your site is
about. If users can't find your site, it won't matter how useful or elegant
it is.
A partial keywords tag for the Acme seed company might look like this:
<META name=keywords content="seeds, mail order, annuals, sun annuals,
shade annuals, perennials, Acme, bulbs, vegetables, herbs, gardening accessories,
plant accessories, seed-starting equipment, lawn statues, statuary, garden
statues, African Daisy, African Daisy Glistening White, African Daisy Mix,
African Violet Classic Hybrids Mix, African Violet Fantasy Hybrid Teacup,
African Violet Fantasy Hybrid Trailing, Ageratum Leilani Blue, Amaranthus
Hot Biscuits">
A description of the Acme site, for search engines to display in their
results, might look like this:
<META name=description content="Acme Seeds provides a wide selection
of annual, perennial, herb, and vegetable seeds for gardens, along with
gardening supplies, lawn ornaments, and gardening tips">
Write for an International Audience
Websites can be accessed by people all over the world.
To make your site more accessible for international users:
- Keep the language simple. Avoid idioms, jargon and humor.
- Keep sentences simple. Subject-verb-object syntax is the easiest for non-native
speakers to understand.
- Express quantities in a universal format if possible. (Remember that most
of the world uses the metric system.)
For example, write out dates (November 20, 2004) rather than abbreviating
them (Americans would write 11-20-04, while Europeans would write 20-11-04).
Plan for Users with Disabilities (Accessibility Guidelines):
Using the Web can be difficult for users with disabilities. But you can make
it easier by planning your content to accommodate screen readers. You can also
help users with motor disabilities by making your link targets and other clickable
items larger.
- Use the HTML "alt" tag to provide a simple text description of
all graphics, images, or icons. Keep these text descriptions brief and check
to see if they make sense out of context. Also describe the function of each
graphic, if appropriate. Summarize key content of graphs and charts using
the "longdesc" attribute.
- Provide detailed text descriptions for visual content (for example, a chart
or diagram) or auditory content.
- Provide text equivalents or at least detailed descriptions for multimedia
content.
- Consider providing non-text equivalents of text for nonreaders or users
who have difficulty reading.
- If you have image links, make sure you've included text alternatives.
- Make sure link text makes sense when read out of context. (Many screen
readers allow users to tab through the links on a page, so that only the link
text is read.)
- Make sure links are big enough for users with impaired sight or reduced
mobility (such as older users).
- Avoid blinking or moving text. Such text is less usable for most users,
but it can be especially hard for users with disabilities and is impossible
for most screen readers.
- Use headings, lists, and consistent structure for page content. Use style
sheets where possible.
- Use row and column headers even for tables used as formatting devices,
to make table content more understandable when accessed through screen readers.
Remember that screen readers will read tables line by line.
- Avoid frames. If you can't, provide a "noframes" alternative.
- Provide links to download any plug-ins that may be required to view your
content. Provide alternatives for plug-ins that may not be supported by assistive
technologies.
