Exclude URLs from this report
Hide findings on pages you are not responsible for — a section another team owns, or legacy pages out of contract. One pattern per line: a plain substring that matches anywhere in the URL (/medicare/, .aspx) or a slash-wrapped /regex/ (/medicare|medicaid/i); # comments are ignored. A finding is hidden when every affected page matches; for findings with more than 25 pages this is judged by the listed sample. This only changes what this report shows in your browser — every page is still scanned, and your list is saved on this device.

Findings scoped to your excluded URLs, matching this view (counts use the same up-to-25-page sample).
Fix these first
| Issue | Severity | Pages | Who it affects | How to fix | Evidence |
|---|---|---|---|---|---|
| All page content should be contained by landmarks (WCAG criterion undetermined) (rule↗) | Serious | 1686 | — | Wrap all page content in landmarks (header, nav, main, footer) so users can navigate by region. | pages (CSV) |
| Images must have alternative text (WCAG 1.1.1) (rule↗) | Critical | 366 | Without vision, Limited vision | Give every <img> a meaningful alt attribute. Use alt="" only for decorative images so screen readers skip them. | pages (CSV) |
| <html> element must have a lang attribute (WCAG 3.1.1) (rule↗) | Serious | 355 | Without vision, Limited cognitive, language, or learning ability | Add a lang attribute to <html> (e.g. lang="en"). | pages (CSV) |
| Heading levels should only increase by one (WCAG criterion undetermined) (rule↗) | Moderate | 562 | — | Use heading levels in order (h1 → h2 → h3) without skipping; structure, not size. | pages (CSV) |
| Elements must meet minimum color contrast ratio thresholds (WCAG 1.4.3) (rule↗) | Serious | 341 | Limited vision, Without color perception | Increase the contrast between text and its background to at least 4.5:1 (3:1 for large text). Check both light and dark modes. | pages (CSV) |
| Document should have one main landmark (WCAG criterion undetermined) (rule↗) | Moderate | 482 | — | Each page should have exactly one <main> landmark. | pages (CSV) |
| Landmarks should have a unique role or role/label/title (i.e. accessible name) c (WCAG criterion undetermined) (rule↗) | Moderate | 461 | — | When a landmark role/type repeats (e.g. two <nav>s), give each a distinct accessible name with aria-label or aria-labelledby (e.g. "Primary" and "Footer" navigation) so screen-reader users can tell them apart. | pages (CSV) |
| Target size is at least 44×44 CSS pixels (Enhanced) (WCAG 2.5.5) (rule↗) | Moderate | 442 | — | See remediation guidance: https://alfa.siteimprove.com/rules/sia-r111 | pages (CSV) |
