Understanding Accessibility

How can I check if my site is accessible?

Its very easy to check to see if your site complies with the w3c's accessibility recommendations. You can use a variety of automated accessibility tools to scan and analyse any web page for accessibility issues.

You should be aware that automated accessibility tools are only able to automatically check some of the checkpoints. Other checkpoints will need to be verified through other means, normally manual checks. Nonetheless, it is a useful starting point. If your site fails an automatic check, you can infer that it does not meet the WCAG guidelines. The EU and the Irish government both recommend that all web sites in their jurisdiction meet the AA conformance levels.
