| Filtering & focus | ||

Report filter
Narrow results to Links, Images, Forms, Color & contrast, Page structure, or Keyboard & focus. Hand the right report to the right person.

Path & query exclusions
Skip URL patterns during the crawl - event listings, paginated archives, or any section that would inflate results without adding useful findings.
|

Violation suppressions
Hide known false positives or accepted risks from output. Raw audit data is preserved and suppressed items are noted at the bottom of each page.
