Is Your Web Site Accessible?
Sometimes we would like to know quickly if a web page or a web site is accessible. Accurately determining accessibility is not a quick process, but there are some questions we can ask to figure out in a matter of minutes if our site is mostly accessible.
In the following you can read a list of questions which will help you determine if your site contains any of the most frequent errors. What you should be looking for is if you can answer with "yes" to any of the questions. If the answer is "no", most likely you will need to make your site more accessible.
The questions are designed so that they are easy to answer without having too much technical knowledge about web design, web development or accessibility.
The questions mostly follow the structure of WCAG 2.0, but they also ensure that they address the most frequent Section 508 non-compliance issues as well.
