Website Checklist: Accessibility

Back to index

Evaluate your commercial website and be successful.

For your website to be successful you must know who your intended website audience is, what the goal of your web site is, and how the attainment of that goal will be measured. Without this knowledge, it will be hard to achieve success.

Accessibility



Accessibility
Validate the site using the "508 Standards for accessibility". Customer acquisition costs are high and if you haven't tested your site for color blindness you could be turning away 8% of your male visitors.

Text Browser
You might think that no one uses text browsers anymore, and you might be right however some people surf with images turned off especially if they are using their cell phone and paying for bandwidth. Knowing your audience will tell you if it is important for your content to display well in a text browser. However there are other reasons for viewing a text only version of your site. For search engines and crawlers the first text to load on the page can be important. Viewing your page in a text browser will help understand what they see first.

Windows size
Check how the site feels on a variety of window sizes. You do not need to cater to the lowest common denominator but you should at least know what their experience of your site is like.

Font size
Font size is a tricky subject. There are many competing viewpoints on the best practices for how to specify fonts and font sizes. Knowing your audience and your goal should help in making the decision.

Cookies
There are two kinds of cookies, persistent cookies that are written to the visitors hard drive and session cookies which are not. I only use persistent cookies at the visitors request for example with a "Remember me" feature. Persistent cookies should always optional and only used at the visitors request (IMHO). Any page that uses writes a persistent cookie should contain a link to information about what it means. Session cookies are different. I use session cookies in many of my sites. Knowing your audience and the features required will help choose the best method for maintaining "state" (jargon for remembering visitors as they move from page to page.)

Rating services
Use rating service headers to describe the suitability of your content. These ratings are used by net filtering products designed to facilitate safe family browsing. For more information refer to Internet Content Rating Association.
