Milap

Did you know that every time you change a URL (slug), WordPress remembers the old one? It stores these in your database and automatically performs a 301 redirect to the new URL.
However, WordPress core has two major flaws: 
1. It provides no way to see this history in the admin dashboard. 
2. It often fails to record history for hierarchical Pages and certain Custom Post Types.
Slug Trace bridges this gap. It provides a simple, elegant interface to see every previous URL a post, page, or product has ever had. It also includes a “Universal Tracker” that forces WordPress to remember slug changes for Pages and Custom Post Types that are usually ignored by core.
<ul>
<li>Universal Support: Works with Posts, Pages, and any public Custom Post Type (CPT) like WooCommerce Products, Portfolio items, and more.</li>
<li>View Hidden Redirects: Instantly see which old URLs are still pointing to your current content.</li>
<li>The “Page Fix”: Adds a custom engine to ensure WordPress actually records slug history for hierarchical Pages—a feature missing from standard WordPress.</li>
<li>SEO Audit Tool: Perfect for checking if old backlinks are being redirected correctly after a site restructure.</li>
<li>Ultra-Lightweight: Written in clean, optimized PHP. No extra database tables and zero impact on site performance.</li>
</ul>
