No landmarks detected
Screen reader users have no way to navigate by region.
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
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.
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.

Images without alt text are invisible to screen readers.
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.

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

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.

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.

Generic link text like 'click here' doesn't describe the destination.
https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=w%401wt%2eeu&lc… ("Click here")
Generic anchor text ('click here', 'read more', 'learn more') tells screen readers and search engines nothing about the destination.

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.

CColor Contrast (Screenshot)Action20 text elements analyzed, 1 fail WCAG AAREVIEW
Analyzes text contrast against the actual rendered page, including background images, gradients, and overlays that CSS-based tools cannot detect.
1 contrast failures on background images/gradients
These failures are invisible to CSS-based accessibility tools like Lighthouse. The text may be fine on a solid background, but fails when rendered over an image or gradient.
