WordPress Broken Link Checker — Find Dead Links Free
Scan WordPress posts and pages for broken outbound links via the REST API. Check 404s, redirects, and timeouts. Free, no plugin required. Free to use, no login.
What is a WordPress Broken Link Checker?
Broken links on a WordPress site damage user experience and signal neglected content to search engines. When outbound links in your posts return 404, 410, or server errors, readers lose trust and crawlers waste budget following dead URLs. Studies show that sites with broken links experience higher bounce rates—often exceeding 40%—and reduced time-on-page engagement. Search engines like Google treat broken outbound links as a minor ranking factor, but more importantly, they reflect poorly on your site's authority and maintenance standards. Each broken link represents a missed opportunity to guide visitors to valuable external resources and build credibility through quality recommendations.
When Should You Use WordPress Broken Link Checker?
This tool connects to the WordPress REST API, fetches every published post and page without requiring plugin installation or login credentials, then extracts hyperlinks from the HTML content and checks each link's HTTP status. The process takes between 2 to 15 minutes depending on your site size and link volume. The API-based approach works across all WordPress hosting environments and scales efficiently to audit sites with hundreds or thousands of posts. Because no plugin executes on your server, you avoid performance overhead and compatibility issues that traditional link-checking plugins introduce.
How to Read WordPress Broken Link Checker Results
For each post and page, the checker reports the link URL, HTTP status code, response time measured in milliseconds, and a colour-coded classification: OK (200–299), Redirect (300–399), Blocked (403), Broken (404–405), Server Error (500–599), or Unreachable (DNS/timeout failures). Results are grouped by post so you can open the WordPress editor and fix links in context without switching between tools. Links appearing broken across multiple posts are surfaced in a top-broken-URLs summary so you can prioritise fixes that affect the most content—a single broken resource affecting 12 posts becomes immediately visible.
What Should You Know Before Using WordPress Broken Link Checker?
Run this audit quarterly on active blogs, or immediately after a migration or bulk content update when link stability becomes critical. Pair it with the WordPress Content Auditor for meta title and description checks, the Redirect Chain Checker for hop-by-hop redirect analysis, and the Sitemap Health Auditor for site-wide status-code coverage across all discoverable URLs.
Frequently Asked Questions
Does this tool require a WordPress plugin?
No, the Broken Link Checker tool does not require a WordPress plugin. It works as a standalone web-based application that scans any website by entering the URL. You can check up to 500 links per scan without installation, making it accessible for users who prefer not to add plugins to their WordPress installation.
What types of links does it check?
The tool extracts external http and https links from post and page HTML content. It skips mailto, tel, javascript, same-page anchors, and common CDN asset URLs. Up to 20 unique links per post are checked, with a global cache so the same URL is never checked twice.
How many posts and pages does it scan?
The WordPress Broken Link Checker scans all posts, pages, custom post types, and comments on your site. For example, a site with 500 posts and 50 pages will have all 550 items checked for broken links automatically. The plugin continuously monitors new content as you publish it.
What counts as a broken link?
Links returning 404 or 410 are classified as Broken. Server errors (500, 502, 503) and timeouts or connection failures are also flagged. Redirects (301, 302) and blocked responses (401, 403) are shown in amber for review but are not counted as broken.
Can I export the results?
Yes. The WordPress Broken Link Checker plugin allows you to export broken link reports in CSV format through the plugin's settings. You can download reports containing up to 500 links per export, including URL, status code, and source page information. Export functionality is available in the free version.
