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.

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.
Performance issues directly impact user engagement and conversion rates.

LOADING STATUS… div.footer-module__ESbTrq__statusRow > a.link-module__Q1NRQq__link > div.status-indicator-module__razUwq__content > p.text-copy-14 |
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.
Performance issues directly impact user engagement and conversion rates.

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Tables and lists
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more about proper list structure.

Vercel logo nav > div.grid > div > ul.list-none |
These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.
Best practices
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more about the viewport meta tag.

ALandmark Structure5 landmarksPASS
The skip-link anchor (e.g., `href="#main"`) points at an ID that has no corresponding element on the page. Activating the link does nothing -- a silent WCAG 2.4.1 failure that the visual link presence hides. Add `id="main"` (or whichever matches the href) to the target landmark.
Skip link points at an ID that doesn't exist on the page. The link looks fine visually but does nothing when activated -- silent WCAG 2.4.1 failure.
Learn more ▾ ▴
Find the target landmark (typically <main> or the first <h1>) and add `id="..."` matching the skip link's href fragment. Test by tabbing to the skip link and pressing Enter -- focus should jump to the target.

A page should have only one H1. Multiple H1s dilute the document outline.
Multiple H1s blur the page's primary topic — screen-reader users and Google both prefer one H1.
Learn more ▾ ▴
HTML5's outline algorithm technically allows multiple H1s within sectioning content, but no browser implements it. In practice: one H1 per page. Use H2-H6 for subsections.
