Broken Link Checker is a Chrome extension for finding dead, redirected, and working links on any webpage. It is used by SEO specialists, web developers, QA engineers, and content teams to validate links before publishing, during site migrations, and as part of routine content audits. The extension scans every URL on the current page — including anchor tags, navigation elements, meta links, and onclick handlers — and highlights each link with a color-coded status: green for working (200 OK), red for broken (4xx/5xx), and blue for redirects (3xx). Results appear directly on the page, making it easy to locate problems in context without switching to a separate dashboard. Key capabilities: — One-click scanning of all links on any open tab — Visual highlighting of link statuses directly on the page — Filtering by status type (working, broken, redirect) — CSV export with link text, destination URL, HTTP status code, and status description — Detection of URLs in navigation menus, buttons, canonical tags, and onclick handlers All checks run locally in the browser. No data is sent to external servers. No account, login, or API key is required. The extension has no background processes and does not affect browser performance when inactive. Broken Link Checker is used across several common workflows: pre-publish QA for content teams, post-migration link validation for SEO professionals, staging environment review for developers, and CTA verification for marketing teams. The CSV export provides audit-ready reports suitable for internal documentation or client deliverables.
