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 outlined within the "Fix These Issues to Improve Your Score" list on the Accessibility Overview page within the Siteimprove Intelligence Platform.

  1. Select Accessibility from the main menu

  2. Click on Accessibility Overview from the menu

  3. Choose the role you possess within your web team (Editor, Webmaster, Developer) or choose to view all issues by choosing the relevant tabs.

  4. Focus on fixing issues that have the biggest impact on your users as well as your Accessibility Score

Alternatively, all list of issues can be found and filtered in the Issues menu in Accessibility.

The World Wide Web Consortium (W3C) states that "It is not recommended 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.
