<p>Stop losing visitors to broken links. <strong>404 Solution doesn’t just redirect errors to your homepage</strong> – it uses advanced spell-checking and intelligent matching algorithms to <strong>find the actual page your visitor was trying to reach</strong>.</p>
<p>When a visitor hits a broken link like <code>/prodcut/awesome-item</code> (typo), most plugins redirect them to your homepage where they get lost and leave. 404 Solution is different – it <strong>automatically finds <code>/product/awesome-item</code></strong> and redirects them to the right place.</p>
<h4>Why 404 Solution is Different</h4>
<p><strong>Intelligent URL Matching</strong> – Uses sophisticated algorithms (N-gram similarity, Levenshtein distance, multi-word matching) to find the closest existing page, not just blindly redirect to homepage.</p>
<p><strong>Spell-Checking Technology</strong> – Automatically handles typos and URL variations so visitors find what they want even when they misspell URLs.</p>
<p><strong>Zero Configuration</strong> – Works perfectly out of the box with smart defaults. Advanced users have full control over every aspect.</p>
<p><strong>WooCommerce Optimized</strong> – Specifically designed to work with products, categories, variations, and custom post types.</p>
<h4>Core Features</h4>
<ul>
<li><strong>Automatic intelligent redirects</strong> based on the best possible match for the URL</li>
<li><strong>404 error logging</strong> with detailed visitor data and referrer information</li>
<li><strong>Manual redirect creation</strong> for specific URLs to any existing page</li>
<li><strong>Page suggestions shortcode</strong> to display matches on custom 404 pages</li>
<li><strong>Automatic cleanup</strong> removes redirects when URLs match new pages or are no longer used</li>
<li><strong>Regular expression support</strong> for advanced redirect patterns</li>
<li><strong>Debug logging</strong> to troubleshoot redirect behavior</li>
<li><strong>Performance optimized</strong> for sites with 10,000+ pages</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Visitor hits a broken link (404 error)</li>
<li>404 Solution analyzes the URL and compares it to all your existing pages</li>
<li>Intelligent matching finds the closest match using spell-checking algorithms</li>
<li>Visitor is automatically redirected to the correct page</li>
<li>You can review all 404s and create custom redirects as needed</li>
</ol>
<h4>Perfect For</h4>
<ul>
<li><strong>eCommerce sites</strong> (WooCommerce, Easy Digital Downloads) with changing product URLs</li>
<li><strong>Content sites</strong> with evolving permalink structures</li>
<li><strong>Migrated sites</strong> where old URLs need to map to new content</li>
<li><strong>Large sites</strong> with thousands of pages where manual redirects are impractical</li>
<li><strong>Any WordPress site</strong> that wants to provide better user experience</li>
</ul>
<h4>What Makes This Different From Other Redirect Plugins?</h4>
<p><strong>vs. Redirection</strong> – Redirection requires manual redirect rules. 404 Solution automatically finds matches using intelligent algorithms.</p>
<p><strong>vs. 404 to 301</strong> – 404 to 301 redirects everything to your homepage. 404 Solution finds the actual page visitors want.</p>
<p><strong>vs. Simple 301 Redirects</strong> – Simple 301 only does manual redirects. 404 Solution creates intelligent automatic redirects based on URL similarity.</p>
<h4>Technical Details</h4>
<ul>
<li>Supports 301 (permanent) and 302 (temporary) redirects</li>
<li>N-gram similarity scoring for fast matching</li>
<li>Spell-checking with Levenshtein distance calculation</li>
<li>Custom post type support (products, events, portfolios, etc.)</li>
<li>Taxonomy-aware (categories, tags, custom taxonomies)</li>
<li>Query parameter preservation</li>
<li>Referrer tracking and logging</li>
<li>IP address logging (GDPR-compliant hashing available)</li>
<li>Automatic performance optimization for large sites</li>
</ul>
<p><strong>Note:</strong> For high-traffic sites with thousands of simultaneous users, disable “Create automatic redirects” and avoid using the shortcode to ensure optimal performance.</p>


404 Solution


I haven't tried all of the features that this plugin has to offer as I intended to just use it temporarily to redirect users to a designated 404 page, but it does so much more. I really appreciate the logs that show me the crazy urls people/bots are trying to access. Had a minor issue with a php notice that I reported, and the developer quickly jumped on it and released an update. Kudos!


Works as expected; fast support!

The smartest 404 plugin for WordPress - finds what your visitors were actually looking for.

<p>If you don’t like the typical 404 page than you can redirect all 404 page not found errors permantly (or temporarily) to the start page or any other site/page you like.</p>
<p>This will help you solve problems with external bad links which are not under your influence.</p>
<p>Chose between 301 – Moved permanently (default) and 302 – Moved temporarily.</p>
<h3>Remove plugin</h3>
<ol>
<li>Deactivate plugin through the ‘Plugins’ menu in WordPress</li>
<li>Delete plugin through the ‘Plugins’ menu in WordPress</li>
</ol>
<p>It’s best to use the build in delete function of wordpress. That way all the stored data will be removed and no orphaned data will stay.</p>
<h3>To do</h3>
<p>More translations. Does someone wants to help?</p>
