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>

This plugin contains the lastViewed widget. This widget shows the users recently viewed/visited Posts, Pages, Custom Types and even Terms in a widget. Very nice to use in combination with Woo-commerce! 
Using caching plugins? No problem! By 2 easy clicks you can bypass the caching and still get the best performance out of this widget.
The widget is fully customisable:
<ul>
<li>Filter on Types and Terms</li>
<li>Set the maximum</li>
<li>Set thumbnail on/off</li>
<li>Show Content(rich or plain) or Excerpt</li>
<li>Set the excerpt length</li>
<li>Add links to elements</li>
<li>Set cookie lifetime</li>
<li>Set cookie same site</li>
<li>Set cookie secure</li>
<li>Set cookie by PHP or JS</li>
<li>load widget with PHP or AJAX</li>
</ul>
customise the widget template by copy the file “dd-templates/lastviewed-widget.php” from the plugin directory into your theme directory. You can now start customising the widgets template.
If one of the posts with the filtered types or terms gets visited in the front, a cookie sets/updates with an array of visited ids. Each widget has his own cookie, so you can set as many widgets as you want.
