A quick Web Accessibility Checklist
Often we hear people asking how can they check for a website for accessibility and what needs to be checked. Here is a quick checklist and hope this would be handy to someone!
- Is the link “Skip to main content” exist? Although, there are several other ways to achieve quick navigation by providing heading mark-up, aria land marks, it’s still easier to hit on one link to reach the main content.
- Does the website provides any accessibility options, such as “Color options” “Font re-size option” etc? This would be good, if your target audience have learning difficulties or new to internet users, else, a help page with an article how one could use the existing accessibility options within the browsers would be helpful.
- Does all the informative images have appropriate alternate text?
- Does decorative images has given empty alt text i.e. alt=””?

- Does all the links have descriptive screen text?
- If an audio content is present, is there a synchronized captions or a text transcript available?
- If CAPTCHA is present, is it accessible to screen reader users and to Braille Display users? if not, is there an alternative method provided such as Audio CAPTCHA or logical questions based captcha
- Is semantic mark-up is used to designate headings and lists
- Are Table columns and rows have associated headers using “th” tags?
- Does tables have descriptive table summary and caption?
