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

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.

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

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

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.

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.

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.

Skipping heading levels breaks the document outline. Screen readers may interpret missing levels as structural errors.
Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.
Learn more ▾ ▴
Screen reader users navigate by jumping between headings (H1 → H2 → H3). Skipping (H1 → H3) breaks the sense of hierarchy. Use sequential levels even if you don't like the default styling — restyle with CSS instead. WCAG 1.3.1 (Info and Relationships) treats this as an A failure.

Empty headings appear in the document outline but provide no information.
Empty <hN> tags break the document outline — screen-reader users navigating by heading hit dead silence.

BForm Accessibility2 of 3 controls have issuesREVIEW

| #languageSelector | select | Choose your language | for/id |
| input | search | (What do you want to learn?) | placeholder only |
| #g-recaptcha-response-100000 | textarea | (none) | none |
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.
<textarea name="g-recaptcha-response" id="g-recaptcha-response-100000">
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

Placeholder text disappears on focus and is not a reliable label.
<input type="search">
Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

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.
