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.

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.

404 Error Page

Action

FIX

Soft 404 detected

Soft 404: server returns HTTP 200 for non-existent pages

The server returns HTTP 200 for a path that does not exist. Search engines will index these pages, diluting your real content. Configure your server to return a proper 404 status code for missing pages.

Got: Status: 200 for /beavercheck-404-test-dwvaga

Landmark Structure

Action

7 landmarks

REVIEW

7 landmarks

<main> landmark present

Multiple <main> landmarks (3 found)

A page should have only one <main> landmark.

No <nav> landmark found

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

A page should have only one <main> landmark.

Why this matters

Multiple <main> elements violate the spec — there must be exactly one per page.

Learn more ▾

HTML5 spec: 'authors must not include more than one main element' visible to AT at the same time. Multiple <main>s confuse AT and break the 'jump to main content' shortcut. Refactor to a single <main> with nested <section>/<article>.

Source: HTML5 spec

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.

Source: WCAG 2.1 SC 2.4.1

Heading Hierarchy

Action

13 headings, 1 skip(s)

REVIEW

13 headings, 1 skip(s)

No H1 heading found

Every page should have one H1 that describes the page content.

Heading level skipped: H2 → H4 (missing H3)

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

Every page should have one H1 that describes the page content.

Why this matters

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Learn more ▾

The H1 is the document title for assistive tech and a strong signal to search engines about page topic. Pages without one force screen readers to fall back to the <title> attribute or page chrome. Add a single H1 that names the page's primary subject.

Source: WCAG 2.4.6 / Google Search Central

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.

Form Accessibility

Control	Type	Label	Method
input	text	(搜索资讯、博客、软件……)	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.

Learn more ▾

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).

Lighthouse Accessibility Audits

Score 87/100 — 4 failing, 24 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.

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.
