Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.

Why this matters

Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.

Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Landmark Structure

REVIEW

7 landmarks

<main> landmark present

4 <nav> landmark(s) found

4 of 4 <nav> elements are unlabeled

Multiple navigations need aria-label to distinguish them for screen readers.

Skip navigation link is missing (WCAG 2.4.1)

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Page Structure — as a screen reader sees it

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more ▾

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Source: WAI-ARIA Authoring Practices

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more ▾

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Why this matters

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.

Learn more ▾

Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.

PWA Depth

REVIEW

2 PWA signal(s) surfaced

Manifest declares display="browser" -- no PWA UX

When `display` is `browser` (or unset, which is the spec default), the installed app opens in a regular browser tab -- no install prompt, no standalone window, no app-shell experience. The intended values for a PWA are `standalone` (most common; full-screen, no browser chrome) or `fullscreen` (games / immersive apps). `minimal-ui` is a middle ground (basic browser controls but no address bar).

Manifest has no maskable icon

Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).

Lighthouse Accessibility Audits

Score 89/100 — 3 failing, 25 passed

REVIEW

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Names and labels

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.

Navigation

Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.

Heading Text Quality

2 heading-text-quality issue(s) detected

PASS

2 heading-text-quality issue(s) detected

1 heading(s) are over 120 characters -- likely a misformatted paragraph

Headings beyond 120 characters are almost always full sentences or paragraphs that received heading semantics by mistake (e.g., a CMS editor selected the wrong block type, or a template wrapped a body paragraph in `<h2>`). Screen readers will announce these as "heading" and read the entire paragraph at heading prosody. Affected: - H5: 142 chars

Got: 1 >120-char heading(s)

21 heading(s) are all-uppercase (excluding short acronyms)

Headings rendered in all-uppercase are a styling choice that should be done via CSS (`text-transform: uppercase`), not by typing the text in caps. Capitalized text is read letter-by-letter by some screen readers (e.g., "H-E-L-L-O W-O-R-L-D" instead of "hello world"). It's also a soft signal of CMS-migration artifacts where the original lowercase intent was lost.

Got: 21 all-caps heading(s)

Alt Text Quality

1 of 65 images have issues

PASS

1 of 65 images have issues

1 image(s) missing alt attribute

Images without alt text are invisible to screen readers.

59 decorative image(s) correctly marked

5 image(s) with good alt text

65 images 5 good alt text 59 decorative 1 missing

Issue	Count
missing	1 image(s)

Images without alt text are invisible to screen readers.

Why this matters

Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.

WCAG 2.1 Level A requires text alternatives for non-decorative images. Empty alt='' is fine for decorative; meaningful images need descriptive text. Common fixes: CMS audit + bulk add, build-time linter (alt-text-required ESLint rule), CI gate on Lighthouse a11y score.

Tabindex Anti-Patterns

PASS

0 positive, 1 -1-on-focusable

tabindex="-1" on naturally-focusable <a>

tabindex="-1" removes an element from the keyboard tab order. Naturally-focusable elements (links, buttons, form controls) become unreachable for keyboard users. (Common false-positive: hidden honeypot fields. Verify the element is genuinely interactive before removing the tabindex.)
