Broken Link Checker

Crawls a site to surface broken links (404s, 500s) and reports the source pages so you can fix them fast.

Marketing & SEOBeginner★ 3,913⑂ 496AI score 5/10Last updated: Oct 9, 2026

What it does

  • Crawls internal pages starting from the URL you give it.
  • Flags internal and outbound links returning errors such as 404 or 500.
  • Reports the source page for each broken link so fixes are straightforward.
  • The real procedure lives in the repo's seo/broken-link-checker/WORKFLOW.md; this skill file is the entry point that loads that workflow.

Who it's for

  • Owners of blogs, company sites, or docs sites who need to keep link hygiene.
  • Marketers producing recurring SEO audit reports.
  • Developers cleaning up leftover 404s after a redesign or URL restructure.

Example uses

  1. "Check https://example.com for broken links" → table of 404s plus the pages linking to them.
  2. "Are any outbound links on my blog dead?" → outbound-only status check.
  3. "Collect remaining 404s after the migration and draft a redirect map."

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/broken-link-checker folder from the GitHub repo nowork-studio/notfair-plugin into my ~/.claude/skills/broken-link-checker/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/nowork-studio/notfair-plugin.git && mkdir -p ~/.claude/skills && cp -r notfair-plugin/skills/broken-link-checker notfair-plugin/seo ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/nowork-studio/notfair-plugin.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy both the skill and the referenced workflow folder: cp -r notfair-plugin/skills/broken-link-checker notfair-plugin/seo ~/.claude/skills/
  5. Verify that ~/.claude/skills/seo/broken-link-checker/WORKFLOW.md exists — without it the skill has no instructions.
  6. Restart Claude Code and ask: "check my site for broken links".
