Must-Have Redirect is an intelligent 404 handling and URL redirection plugin. There are 2 available plans:

Single plan

You can use Must-Have Redirect with Single plan for 1 WordPress site. It's perfect if you have a single site or want to test the plugin's capabilities.

Configuration

Configure the basic functionality of the plugin in this section.

Smart 404 Handling

When enabled, the plugin automatically tries to find and redirect to the most relevant content when a 404 error occurs. This feature uses intelligent similarity matching to find the best possible destination.

Similarity Threshold

Choose how strict the plugin should be when matching similar content:

  • Close Match (10% difference): Only redirects to very similar URLs, best for catching minor typos
  • Likely Relevant (25% difference): Balanced approach, catches moderate URL variations
  • Fallback (50% difference): Most lenient, tries to avoid 404s by finding any potentially relevant content

Custom 404 Page

Select any WordPress page to serve as your custom 404 page. This page will be displayed when:

  • No matching redirect rule is found
  • No similar content is found
  • The found destination would create a redirect loop

Redirect Rules

Manage your redirect rules and view automatically generated redirects.

Manual Redirects

Create redirect rules with these options:

  • Pattern: The URL pattern to match (supports wildcards)
  • Destination: Where to redirect matching URLs
  • Status: HTTP status code (301 permanent, 302 temporary)

Wildcard Patterns

Use * as a wildcard in your patterns. Examples:

  • old-product/* → Matches all URLs starting with "old-product/"
  • *.html → Matches all URLs ending with ".html"

URL Handling

Learn how the plugin processes and normalizes URLs.

URL Normalization

The plugin automatically normalizes URLs for consistent matching:

  • Removes trailing slashes
  • Removes tracking parameters (utm_*, fbclid, etc.)
  • Sorts remaining query parameters alphabetically

Ignored Query Parameters

These query parameters are automatically removed:

  • UTM parameters (utm_source, utm_campaign, etc.)
  • Social media parameters (fbclid, fb_action_ids, etc.)
  • Analytics parameters (_ga, gclid)
  • Other tracking parameters (age-verified, rdt_cid, li_fat_id)

Bot Protection

The plugin automatically detects and skips processing for:

  • Empty or suspicious user agents
  • Known bot/crawler user agents
  • Malicious URL patterns
  • Direct file access attempts

Best Practices

  • Start with "Close Match" similarity and adjust based on your needs
  • Review auto-generated redirects periodically
  • Use wildcards carefully to avoid unintended matches
  • Monitor hit counters to identify frequently used redirects
  • Consider creating permanent (301) redirects for commonly used patterns

Available Filters

Customize the plugin's behavior using these filters:

mhredirect/current_path

Modify the normalized path before processing:

// Modify the normalized path
add_filter('mhredirect/current_path', function($path) {
      // Your modifications here
      return $path;
});

mhredirect/remove_query_params

Customize which query parameters to remove:

// Customize which query parameters to remove
add_filter('mhredirect/remove_query_params', function($params) {
      $params[] = 'my_tracking_param';
      return $params;
});
                        

mhredirect/similarity_threshold

Customize similarity threshold for specific words:

// Customize similarity threshold for specific words
add_filter('mhredirect/similarity_threshold', function($threshold, $word1, $word2) {
      // Your custom logic here
      return $threshold;
}, 10, 3);
