Description

Maintaining a healthy internal link architecture is critical for search engine rankings and smooth user experiences. ODC Internal Link Integrity Scanner is an on-demand maintenance tool designed to identify dead ends and eliminate inefficient internal redirect hops across your entire site.

Unlike heavy, automated monitoring plugins that constantly poll databases and bloat background server processes, ODC Internal Link Integrity Scanner runs strictly when initiated via safe AJAX batch requests.

Key Features

  • Comprehensive Internal Auditing: Scans Posts, Pages, Custom Post Types, Navigation Menus, Block Theme Templates (Header/Footer), and Widget Areas.
  • 404 & 301/302 Detection: Flags missing pages (404 Not Found) and outdated paths (301/302 Moved Permanently).
  • 1-Click Auto-Replace Engine: Instantly rewrites outdated 301 redirected links directly in the database with their final destination URL without opening the editor.
  • Server-Safe AJAX Batching: Processes items in small throttled batches, preventing PHP timeouts and server crashes on large sites.
  • Hardened Security: Built using strict WordPress standards, including cryptographic nonce verifications, user capability checks, validated widget option access, and SSRF prevention via wp_safe_remote_head().
  • Zero External Dependencies: Built with native WordPress Dashicons and scripts—no external fonts, CDNs, or tracking scripts.

SEO Benefits

  • Preserves Crawl Budget: Eliminates unnecessary redirect hops so search engines index your key content faster.
  • Protects Link Equity: Directs PageRank and anchor relevance straight to destination endpoints without dilution.
  • Faster User Experience: Prevents latency caused by multiple server-side redirect chains.
  1. Upload the odc-internal-link-integrity-scanner folder to your /wp-content/plugins/ directory, or install the plugin directly through the WordPress plugins screen.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Navigate to Tools > Link Integrity Scanner to launch your first scan.
Does this plugin run continuously in the background?

No. ODC Internal Link Integrity Scanner is built as an on-demand audit tool. It only runs when you manually click “Start Comprehensive Audit,” ensuring zero background server drag or database bloat.

Does this plugin check external links?

No. This tool is strictly optimized for internal link health (links pointing to your own domain name).

What does the “Auto-Replace” button do?

When an internal link returns a 301 or 302 redirect status, the scanner determines the final destination URL. Clicking “Auto-Replace” safely updates the source text in your database to point directly to that destination.

Can I scan custom post types?

Yes. Any custom post type registered as public => true (such as WooCommerce products, portfolios, and recipes) is automatically included in the audit.
