Query2Slug

Description

Query2Slug lets you turn filtered WordPress pages into clean, canonical URLs — perfect for ad campaigns (Google Ads, Meta), SEO landing pages, and shareable links.

Instead of sending users to ugly URLs like:

/shop/?product_cat=t-shirt&product_tag=disney

You create a clean slug that resolves to the same filtered view:

/lp/t-shirt-disney/

No pages to create. No content to duplicate. Just a simple mapping.

How it works

  1. Set a URL prefix (default: lp)
  2. Create rules that map a slug to a set of query parameters
  3. The plugin registers rewrite rules and handles canonical redirects automatically

Key features

  • Clean campaign URLs — create pretty URLs for any combination of query parameters
  • Canonical redirect — visitors arriving via query strings are automatically redirected (301) to the clean URL
  • UTM preservation — tracking parameters (utm_source, fbclid, gclid, etc.) are preserved through redirects
  • WooCommerce-friendly — works with product categories, tags, and attributes out of the box
  • Works everywhere — not limited to WooCommerce; supports any WordPress taxonomy or query var
  • Autocomplete — filter editor suggests registered taxonomies and their terms
  • Zero frontend impact — no CSS or JavaScript added to your site’s frontend

Use cases

  • Google Ads / Meta campaign landing pages
  • SEO-friendly filtered archive pages
  • Clean shareable links for filtered product collections
  • Any scenario where you need a pretty URL for a query string

Screenshots

  • Rules list with status toggle, URL preview, and filter summary
  • Rule editor with slug preview and filter autocomplete
  • Settings page with URL prefix configuration and overview widget

Installation

  1. Upload the query2slug folder to /wp-content/plugins/
  2. Activate the plugin through the WordPress admin
  3. Go to Query2Slug > Settings to configure your URL prefix
  4. Go to Query2Slug > Add Rule to create your first mapping

FAQ

Does this plugin require WooCommerce?

No. Query2Slug works with any WordPress site. WooCommerce taxonomies and attributes will appear in the autocomplete when WooCommerce is active, but the plugin functions independently.

What happens if I deactivate the plugin?

All your rules are preserved in the database. The clean URLs will simply stop working (return 404) until you reactivate. No content is lost.

Can I use this with custom taxonomies?

Yes. Any registered public taxonomy will appear in the filter key autocomplete.

How does the canonical redirect work?

If a visitor arrives at a URL with query parameters that exactly match a rule (e.g., ?product_cat=t-shirt&product_tag=disney), the plugin issues a 301 redirect to the clean URL. UTM and tracking parameters are preserved.
