275 links and buttons have descriptive text

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

https://pck-nbcapp.co/insider ("MORE"); https://www.nbcsports.com/?ref=nbcdotcom ("More"); https://www.nbcuniversalprivacy.com/privacy#accordionheader5 ("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.

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.

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.

404 Error Page

HTTP 403, bare page

Unexpected status code: HTTP 403

Every page should have one H1 that describes the page content.

Why this matters

No H1 means screen-reader users can't identify the page's primary topic, and Google's content-extraction degrades.

Learn more ▾

The H1 is the document title for assistive tech and a strong signal to search engines about page topic. Pages without one force screen readers to fall back to the <title> attribute or page chrome. Add a single H1 that names the page's primary subject.

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.

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.

Best practices

Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.

Why this matters

Performance issues directly impact user engagement and conversion rates.
