3 control(s) without accessible label
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

<input type="submit">; <input type="submit" id="gform_submit_button_1">; <textarea name="g-recaptcha-response" id="g-recaptcha-response-100000">

Why this matters

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

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.

Alt Text Quality
1 of 44 images have issues
PASS
1 of 44 images have issues
Critical::
1 image(s) missing alt attribute

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.

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
Learn more div.fc-dialog-content > div.fc-dialog-scrollable-content > button.fc-faq-header > span.fc-faq-label
List of partners. div.fc-dialog-scrollable-content > div.fc-footer > p > a.fc-vendors-list-dialog
Manage options div.fc-dialog > div.fc-footer-buttons-container > button.fc-button > p.fc-manage-options-third-button-label

These are opportunities to improve the legibility of your content.

Names and labels

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.
