Broken Link Checker is one of the longest-running link monitoring plugins for WordPress, helping site owners detect and fix broken links before they harm SEO rankings and user experience. The plugin scans your entire site — posts, pages, comments, custom post types, and even external links — checking for HTTP errors, redirects, and connection timeouts. Every broken link is flagged with its URL, the page it appears on, and the HTTP status code returned, allowing you to edit the link directly from the scan results page. For SEO-sensitive sites where link health matters, this is the counterpart to on-page optimization tools like Rank Math SEO, which focuses on content optimization while Broken Link Checker handles technical link maintenance.
The plugin uses WordPress cron for scheduled scans and processes links through parallel HTTP requests to minimize scan duration. Detected issues can be fixed in bulk, with options to unlink, replace, or redirect broken URLs.
Competitive Features
- Automated link scanning — scheduled scans check all internal and external links for HTTP errors, redirects, and timeouts
- Real-time monitoring — optional continuous monitoring checks new and edited posts as they are published
- Bulk editing — fix multiple broken links at once by unlinking, replacing URLs, or setting redirects in bulk
- Email notifications — receive daily or weekly digests of new broken links detected on your site
- Link rechecking — verify that fixed links are working by rechecking only repaired URLs
- Custom post type support — scan all custom post types, categories, tags, and custom taxonomy descriptions
- Dashboard widget — at-a-glance view of link health status with counts of broken, redirected, and valid links
Key Features
- HTTP status detection — identifies 400 and 500 errors, 301 and 302 redirects, DNS failures, and connection timeouts
- Inline link editor — edit or remove broken links directly from the scan results table without opening the original post
- URL replacements — replace a broken URL across all posts and pages with a single bulk operation
- Scan scheduling — configure scan frequency from hourly to weekly, with automatic pauses during high-traffic periods
- Link exclusions — exclude specific URLs, domains, or URL patterns from scanning to reduce noise from known external services
- Redirect tracking — identify links that return redirects and optionally update them to the final destination URL
- CSV export — export broken link reports to CSV for offline analysis or client reporting
Comparison with Competitors
Broken Link Checker Pro vs Link Whisper
| Aspect | Broken Link Checker Pro | Link Whisper |
|---|---|---|
| Primary function | Detect broken links | Suggest internal links |
| Broken link detection | Yes (comprehensive) | No |
| Internal link suggestions | No | Yes (AI-based) |
| Bulk URL replacement | Yes | No |
| External link checking | Yes | No |
| Scan scheduling | Yes | On-the-fly |
| Dashboard reports | Yes | Yes |
Bottom line: These are complementary tools, not direct competitors. Broken Link Checker Pro finds and fixes dead links, while Link Whisper suggests new internal linking opportunities. For complete link management, use both — Broken Link Checker to maintain existing links and Link Whisper to build new ones.
Broken Link Checker Pro vs AIOSEO Pro Link Assistant
| Aspect | Broken Link Checker Pro | AIOSEO Pro (Link Assistant) |
|---|---|---|
| Broken link detection | Yes | Yes |
| Internal link suggestions | No | Yes |
| External link detection | Yes | Yes |
| Bulk URL replacement | Yes | No |
| Scheduling | Flexible (hourly+) | Limited |
Bottom line: AIOSEO Pro’s Link Assistant is a good option if you already use AIOSEO and want link management as part of a broader SEO toolkit. Broken Link Checker Pro is the better standalone tool with more flexible scheduling and bulk operations.
Recommended Stack: Broken Link Checker Pro handles link maintenance. For page speed optimization alongside clean link profiles, pair it with WP Rocket — faster loading pages rank better, and fewer broken links improve user experience.

Frequently Asked Questions
Does Broken Link Checker slow down my site?
The plugin does not affect front-end performance — scans run in the background via WordPress cron. For large sites, it’s recommended to schedule scans during low-traffic hours. The plugin processes links in small batches to avoid overloading your server.
Can I check links in custom post types?
Yes. Broken Link Checker scans all public post types including custom post types, as well as categories, tags, and custom taxonomy descriptions. You can enable or disable specific content types from the scan settings.
How does the bulk URL replacement work?
You enter the old URL and the replacement URL, select the posts you want to update, and the plugin replaces all instances across the selected content. This is useful when an external resource moves or when you update your CDN domain.
What HTTP status codes does it detect?
The plugin detects all 4xx client errors (400, 401, 403, 404, 410), 5xx server errors (500, 502, 503), redirects (301, 302, 307), and connection failures (DNS, timeout, SSL errors). Each error type is color-coded in the results table.
Is there a free version?
Yes. The free version on WordPress.org includes scheduled scanning, email notifications, and basic link management. The Pro version adds continuous monitoring, bulk URL replacement, regex support, advanced exclusions, and CSV export.
