A page should have only one H1. Multiple H1s dilute the document outline.
Why this matters
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.
Source: WCAG 2.4.6 / Google Search Central
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.

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.

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.

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.
ARIA
ARIA roles must have valid values in order to perform their intended accessibility functions. Learn more about valid ARIA roles.
Why this matters
