Everything LinkSweep checks
LinkSweep runs 13 checks across your whole site on a schedule you choose — broken links and images, SEO and accessibility issues, slow pages, security headers, mixed content, redirect chains and outdated content. It renders JavaScript sites in a real browser, works with common firewalls, and delivers a report grouped by severity so you know what to fix first.
The checks
Broken links →
404s, server errors and network failures on internal and external links.
Broken images →
Image sources that return nothing, on every page.
JavaScript & SPA crawling →
Real-browser rendering for React, Vue, Angular, Next.js and more.
Accessibility →
Missing lang, unlabeled inputs, inaccessible links and missing alt text.
Redirect chains →
3+ hops flagged as a warning, 5+ as an error.
Mixed content →
Insecure HTTP resources loaded on HTTPS pages.
Outdated content →
Stale copyright years, past dates and pages not updated in over a year.
