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

Generic link text like 'click here' doesn't describe the destination.

https://corporate.flix.com/flix-sustainable-travel/flix-innovation-catalyst-pioneer/ ("here")

Why this matters

Generic anchor text ('click here', 'read more', 'learn more') tells screen readers and search engines nothing about the destination.

Learn more ▾

Out-of-context lists of links read by AT (one navigation pattern) become useless when every link says 'click here'. Use the destination's title or topic as anchor text. Doubles as SEO win — Google passes anchor-text relevance to the destination.

Web Manifest

No web manifest found

No manifest at standard paths (/manifest.json, /site.webmanifest). A manifest is optional but enables PWA features like home screen installation and standalone display.

Dark Mode Support

Theme color only

FIX

Theme color only

Theme-color present but no dark variant

A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.

Got: #97d700

No dark mode signals detected

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

Detection limited to meta tags and inline styles

Alt Text Quality

3 image(s) missing alt attribute

Images without alt text are invisible to screen readers.

Issue	Count

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.

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.

Lighthouse Accessibility Audits

Score 93/100 — 2 failing, 32 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.

Names and labels

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
div.iBR9R > div.wFRu3 > span.hcr-tooltip-target-13-6-1 > button.hcr-btn-13-6-1 `div.iBR9R > div.wFRu3 > span.hcr-tooltip-target-13-6-1 > button.hcr-btn-13-6-1`

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.
