Web Site Accessibility
and Web Standards -- Get More Visitors and Make More Money
By Jim Byrne
Most website commissioners are not interested in Web Standards
or Web accessibility - that is clear from the results of DRC
Research carried out in the UK in 2004. The research highlighted
the appalling lack of accessibility of most UK web sites - with
81% labelled by researchers as 'impossible' to use by many disabled
people.
So if you are a web developer, don't waste your time trying
to get clients excited by your ethical approach. Instead just
get on with the job of creating accessible standards based
websites -- and tell them you use development methods that
will help them attract more visitors -- and help them make
more money.
Use Web Standards -- money can be saved and money can be
made
Pages built using web standards tend to be smaller and they
tend to load quicker. This leads to the first and most obvious
saving -- lower bandwidth costs. What is not so obvious, however,
is that faster loading pages can also generate additional
traffic and revenue. For example, when Multimap.com redesigned
their site using web standards they estimated they saved 40,000
Gb of bandwidth per year -- but they also found that their
advertising revenues increased. The quicker loading pages
encouraged people to spend more time on the site - and consequently
advertising revenues went up.
Accessible websites make more money
Julie Howell, Digital Policy Development Officer at the RNIB,
talking about one of Tesco's websites -- a website designed
to provide easier access for blind and visually impaired people,
"Many fully-sighted people find Tesco’s simply
designed Access site offers them a better user experience
than any other supermarket website. Developed for vision-impaired
users, it now takes a surprising £13 million a year,
and seems to attract a much wider audience than originally
intended."
Accessible websites attract more people
Apart from the 10 million Disabled people in the UK and 50
million in America, accessible websites will be easier to
use by older people, people with slow connections or older
technologies and people with low literacy. Older people are
the fastest growing group of new users in many countries.
As many older people have multiple impairments, accessible
sites are likely to be more attractive to this group.
Disabled people and older people have money to spend
In the UK Disabled people have £50 billion of disposable
income, in the USA they have US$175 billion. Older people
currently control over 80% of the wealth of the UK. As was
demonstrated by Tesco -- making your website even a little
more accessible not only brings you good press -- it attracts
the attention of the community of older people and disabled
web surfers - who spend their money on your website rather
than your competitors.
Web Standards means shorter development times and re-usable
content
Production and maintenance costs are lower when content is
package in highly structured ways, for example, when standard
(X)HTML is used. Separating the structure of content, i.e.,
headings, lists, images, paragraphs, from the way that content
is presented opens up opportunities to create multiple 'views'
of that content. As a result, content can be optimized with
less effort for delivery on hand-held devices, formatted for
printing or delivered to assistive devices such as screen
readers. When the time comes around for a new design, it is
easier to substitute a new style sheet than to spend hours
changing hundreds of font tags and background colour attributes.
Web standards means you don't waste time battling with Browser
quirks
When using Web standards there is no need to produce multiple
versions of pages to cope with the quirks of different browsers.
The time and effort previously required to create and maintain
'browser sniffing' scripts can now be re-deployed to add value
to the site for visitors.
Web standards helps you break free from proprietary technologies
Using Web standards can free organisations from being captives
of browsers dependent on proprietary tags and rendering behaviour.
For example, IBM's move to Open Source desktop clients has
reportedly been held back due to their web based systems being
built on top of the non-standard Internet Explorer web browser.
Less errors in pages means less time dealing with complaints
Without working to standards - it is not possible to check
for markup errors; there are no rules to check against. Standards
base web pages can be checked against code validators such
as the W3C validator - highlighting any errors - and allowing
you to get those errors fixed. If you website works for more
people on more browsers you won't have to spend time replying
to emails from people complaining your site doesn't work.
Content is future-proofed and compatible with older browsers.
Pages built using web standards will display more consistently
across browsers and platforms, including older browsers. Your
content will not necessarily look the same in old 'non-standard
compliant' browser but the bottom line is that the content
will still be available.
Greater search engine visibility
Search engines are able to index web pages more accurately
if the content on those pages is well structured. For example,
when keywords appear in page headings many search engines
give extra weight to those words when indexing the page. A
web page where headings are improperly marked up is likely
to suffer in the search rankings compared with a page with
the same content that is marked up correctly. An accessible
website will have alternative text for images and multimedia
- and this will provide more text be indexed by search engines.
Accessible websites designed using Web Standards leads to
real measurable benefits: more visitors, increased income,
decreased cost, greater search engine visibility, faster loading
and easier to use pages. Sell the benefits to websites commissioners,
not the ideology.
