Which issues in Accessibility are the most important to fix?

Siteimprove categorizes accessibility issues in accordance with WCAG 2.0 guidelines. You have encountered several accessibility issues found on your sites categorized by severity (A, AA, AAA) but which ones are most important to fix? Level A accessibility criteria covers the most basic accessibility issues while AAA criteria is the highest level of accessibility. It will be very difficult for a website to conform to all criteria on level AAA. For this reason the recommendation is to address accessibility issues based on priority pages and target groups. Most organizations choose to strive for AA conformance level (which consists of A and AA issues).
If you want to focus your efforts on issues that will immediately make a significant difference for users with disabilities and users of assistive technologies, work on fixing issues categorized within the Priority Issues list.

Click one of the options displayed in the Priority Issues list to visit the Issues page displaying issues specific to the category selected in the Accessibility Overview.

Alternatively, Priority Issues (along with all other issues) can be found and filtered in the Issues menu in Accessibility.

After fixing issues in the Priority list we recommend that you continue by fixing A issues as those types of issues can have a damaging effect on the user experience of people with disabilities. AA issues are next in line to fix. By fixing AA issues you can make sure that almost all users will be able to use the website and get a good experience on your site. When all of your Priority, A, and AA issues have been fixed, you can start focusing on AAA issues. 

The World Wide Web Consortium (W3C) states that "Level AAA conformance be required as a general policy for entire sites because it is not possible to satisfy all Level AAA Success Criteria for some content." Some content can be very difficult to conform to AAA success criteria (e.g. having captions, audio description, AND sign language interpretation on all video content) and sometimes you might run into criteria that clash slightly with each other. 

Note: You should always evaluate your user target group to best know which standards need to be complied with. So for instance, if your target user group is blind people then it would make sense to implement AAA standards that are useful for blind people.
