Everything LinkSweep checks

LinkSweep runs 14 checks across your whole site on a schedule you choose — broken links and images, malicious links, SEO and accessibility issues, slow pages, security headers, mixed content, redirect chains and outdated content.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 — with the last working copy from the Wayback Machine suggested for dead external pages.

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Outdated content →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.

Malicious & hijacked links

Outbound links that Google Safe Browsing lists, and links to domains that expired and now serve a for-sale, parked or spam page.

SEO issues

Missing titles, meta descriptions, Open Graph tags and image alt text.

Slow pages

Pages that take over five seconds to respond.

Security headers

Missing CSP, HSTS, X-Frame-Options and X-Content-Type-Options.

Missing references

Action links like "read more" that point nowhere.

Bot-blocked links

Reported as information, with allowlist guidance when a firewall blocks us.

How a scan works

  1. Add a domain.
  2. LinkSweep discovers pages from your XML sitemap and internal links.
  3. It renders JavaScript in a real browser when a page needs it.
  4. It checks links, images, metadata, accessibility, speed, headers and freshness.
  5. It prioritises findings and delivers them by your chosen channel.
