Alt Text Quality

Action

5 of 23 images have issues

FIX

5 of 23 images have issues

5 image(s) missing alt attribute

Images without alt text are invisible to screen readers.

5 image-in-link without alt text

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

14 decorative image(s) correctly marked

4 image(s) with good alt text

23 images 4 good alt text 14 decorative 5 missing

Issue	Count
missing	5 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.

Link & Button Quality

Action

12 issue(s) across 178 links and 18 buttons

6 image-only link(s) without alt text

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.

Source: WCAG 2.1 SC 2.4.4

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

Why this matters

Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.

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

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.owl-dot (#579 on page); button.owl-dot (#581 on page); button.owl-dot (#583 on page); button.owl-dot (#585 on page); button.owl-dot (#587 on page)

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.

Lighthouse Accessibility Audits

Action

Score 45/100 — 4 failing, 2 passed

FIX

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

The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search. Learn more about document titles.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
html `html`

Screen reader users rely on frame titles to describe the contents of frames. Learn more about frame titles.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
body > iframe#main-iframe `body > iframe#main-iframe`

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.

Internationalization and localization

If a page doesn't specify a `lang` attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more about the `lang` attribute.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
html `html`

These are opportunities to improve the interpretation of your content by users in different locales.

Best practices

One main landmark helps screen reader users navigate a web page. Learn more about landmarks.

Landmark Structure

PASS

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.
