Landmark Structure

Action

1 landmarks

FIX

1 landmarks

No <main> landmark found

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

No <nav> landmark found

No banner (header) 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.

Page Structure — as a screen reader sees it

Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.

Why this matters

Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.

Learn more ▾

The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.

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.

Alt Text Quality

Action

2 of 5 images have issues

FIX

2 of 5 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.

3 decorative image(s) correctly marked

5 images 3 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.

Source: WCAG 2.1 SC 1.1.1 / WebAIM Million Report

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.

Link & Button Quality

Action

3 issue(s) across 5 links and 0 buttons

FIX

3 issue(s) across 5 links and 0 buttons

Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.

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.

Heading Hierarchy

No headings

REVIEW

No headings

No headings found

Headings (H1-H6) create the document outline for screen reader navigation.

No headings found

Headings create the document outline for screen reader navigation.

Headings (H1-H6) create the document outline for screen reader navigation.

Why this matters

A page with zero headings is unnavigable by assistive tech and reads as one undifferentiated wall of text.

Learn more ▾

Screen reader users navigate by jumping between H1-H6 elements. A page with no headings has no skip targets — users have to read every word linearly. Adding a heading hierarchy (one H1, then H2 sections, optional H3 subsections) makes the page skimmable for both AT and human readers.

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

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.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
footer > div > a > img `footer > div > a > img`
footer > div > a > img `footer > div > a > img`

Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn how to make links accessible.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
body > div#vivo > a `body > div#vivo > a`
body > div#vivo > a `body > div#vivo > a`
body > div#vivo > a `body > div#vivo > a`

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.
