Heading Hierarchy

REVIEW

42 headings, 1 skip(s)

Multiple H1 headings (2 found)

A page should have only one H1. Multiple H1s dilute the document outline.

Heading level skipped: H1 → H3 (missing H2)

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

A page should have only one H1. Multiple H1s dilute the document outline.

Why this matters

Multiple H1s blur the page's primary topic — screen-reader users and Google both prefer one H1.

Learn more ▾

HTML5's outline algorithm technically allows multiple H1s within sectioning content, but no browser implements it. In practice: one H1 per page. Use H2-H6 for subsections.

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.

Learn more ▾

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.

Heading Text Quality

3 heading-text-quality issue(s) detected

REVIEW

3 heading-text-quality issue(s) detected

1 heading(s) are too short (≤2 characters) to convey meaning

Headings with 2 or fewer characters are almost always emoji / typos / alignment hacks rather than real headings. Screen readers announce the heading level ("heading 2") and then read the content -- a single-character heading conveys no information. Affected: - H3: "\u200b"

Got: 1 ≤2-char heading(s)

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: - H2: 123 chars

Got: 1 >120-char heading(s)

5 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: 5 all-caps heading(s)

Why this matters

Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.

Add '(opens in new tab)' to link text or aria-label.

https://www.google.com/search?sca_esv=2a6646da058cd39e&si=AMgyJEtREmoPL4P1I5I…

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.

Icon-only buttons need an aria-label so screen readers can announce them.

button#comp-kd5px9q0_r_comp-kkmqi5tc

Why this matters

Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.

Mobile Keyboard & Autofill

Action

3/5 eligible field(s) missing autocomplete or inputmode

REVIEW

3/5 eligible field(s) missing autocomplete or inputmode

3 field(s) would benefit from inputmode attribute

Mobile browsers pick the on-screen keyboard layout from `inputmode=` when present (numeric pad, tel dialpad, email keyboard). Without it, users see the default text keyboard and must mode-switch -- 2-3 extra taps per phone-number or numeric-ID field. Type-based defaults exist (`type=tel` shows the tel keyboard on most browsers) but `inputmode` is the explicit, cross-browser way to control this. Affected types: email, tel, numeric.

Got: <input type="email" name="email" id="input_comp-mh99ypli5">, <input type="tel" name="phone" id="input_comp-mh99yplk">, <input type="number" name="zip-code" id="input_comp-mh9h54yn">

Landmark Structure

14 landmarks

PASS

14 landmarks

<main> landmark present

3 <nav> landmark(s) found

All <nav> elements are properly labeled

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

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.

No `<meta name="theme-color">` -- browser chrome falls back to default

Without `theme-color`, Android Chrome's status bar and iOS Safari's toolbar fall back to a generic gray. Adding a single hex color in `<meta name="theme-color" content="#0066cc">` tints them to your brand color across all mobile browsers.

iOS auto-link for phone numbers disabled (`format-detection: telephone=no`)

The page sets `<meta name="format-detection" content="telephone=no">`, which prevents iOS Safari from auto-converting phone-number-shaped strings into clickable `tel:` links. Common reason: the auto-detection rewrites mid-paragraph DOM and breaks CSS selectors / JS that depended on the specific text. If you want clickable phone numbers, declare them with explicit `<a href="tel:+1234567890">` and keep auto-detection disabled.

Lighthouse Accessibility Audits

Score 95/100 — 2 failing, 27 passed

PASS

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.

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.

Why this matters

Performance issues directly impact user engagement and conversion rates.
