Alt Text Quality

Action

2 of 3 images have issues

FIX

2 of 3 images have issues

2 image(s) missing alt attribute

Images without alt text are invisible to screen readers.

2 image-in-link without alt text

An image inside a link with no alt creates an empty link.

1 decorative image(s) correctly marked

3 images 1 decorative 2 missing

Issue	Count
missing	2 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.

Learn more ▾

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.

An image inside a link with no alt creates an empty link.

Why this matters

Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.

Learn more ▾

An <a><img></a> with no img alt is the worst-case for accessibility: AT announces the link but can't describe where it goes. Either add alt to the image OR add aria-label to the link.

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.

No dark mode signals detected

Consider adding CSS with @media (prefers-color-scheme: dark) and <meta name='color-scheme' content='light dark'>.

Print Stylesheet

Action

No print styles

FIX

No print styles

No print-specific styles detected

When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

Landmark Structure

5 landmarks

REVIEW

5 landmarks

<main> landmark present

2 <nav> landmark(s) found

2 of 2 <nav> elements are unlabeled

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

No contentinfo (footer) landmark

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.

Search landmark present

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.

Heading Hierarchy

3 headings

REVIEW

3 headings

Multiple H1 headings (2 found)

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

2 empty heading(s)

Empty headings appear in the document outline but provide no information.

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.

Source: WCAG 2.4.6 / Google Search Central

Empty headings appear in the document outline but provide no information.

Why this matters

Empty <hN> tags break the document outline — screen-reader users navigating by heading hit dead silence.

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.

Contrast

Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Search YouTube `ytm-search-bar-entry-point-view-model > div.search-bar-entry-point-buttons > div.search-bar-entry-point-button > span.search-bar-entry-point-text`

These are opportunities to improve the legibility of your content.

Best practices

Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more about the viewport meta tag.

Form Accessibility

1 of 1 controls have issues

1 control(s) rely on placeholder only

Placeholder text disappears on focus and is not a reliable label.

Got: <input type="text" name="search_query">

0 unlabeled

Control	Type	Label	Method
search_query	text	(Search)	placeholder only

Placeholder text disappears on focus and is not a reliable label.

Why this matters

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).
