2. 📖 Configuration & Verification Guide

The JaJuMa PRG Pattern Link Masking extension is designed for powerful impact with minimal setup.
The configuration is intentionally simple, allowing you to solve complex SEO problems with a single setting. This guide will walk you through enabling the module and, crucially, how to verify for yourself that it is working as intended.

To access the configuration, navigate to
JaJuMa -> PRG Pattern Link Masking
in your Magento Admin.

2.1 ⚙️ Enabling the Extension

The extension's functionality is controlled by a single dropdown field:
Module Enable.

• Yes (Recommended):
  This is the standard setting for all live stores. It enables the PRG Pattern for all applicable links (layered navigation, sorting, pagination), actively preventing crawl budget waste and consolidating link equity.

• No:
  This fully disables the extension, and Magento operates with its default link behavior. This setting should only be used temporarily for specific diagnostic purposes, such as during initial site development or when troubleshooting potential conflicts.

💡 Pro Tip: For most stores, the correct setting is Yes.
You should only disable the module temporarily for specific diagnostic purposes.
Enabling this extension is one of the most impactful single changes you can make to improve your store's technical SEO health.

2.2 🔎 How to Verify the PRG Pattern is Active

Trust, but verify.
This principle is core to effective technical SEO.

You can easily confirm that the PRG pattern is active and protecting your site by using the built-in developer tools in any modern web browser.
This process empowers you to see the extension's request flow in action.

Follow these steps:

1. Navigate to any category page on your storefront that has layered navigation filters.
2. Hover a filter option with your mouse
3. See the bottom left/right corner in your browser
4. The PRG module is
   1. Active if it shows NO link/URL
   2. Not Active if it shows a link/URL

Or take a deep-dive into the technical flow:

1. Navigate to any category page on your storefront that has layered navigation filters.
2. Open your browser's Developer Tools. This can usually be done by pressing F12 or Ctrl+Shift+I (Windows/Linux) or Cmd+Option+I (Mac).
3. Select the Network tab within the Developer Tools.
4. Ensure the "Preserve log" (or similar) checkbox is ticked. This prevents the log from clearing on page redirects.
5. On your category page, click any layered navigation filter (e.g., a color, size, or price range).
6. Observe the new entries that appear in the Network log. You are looking for a specific two-step sequence:
   • First Entry: A request to your category URL with a Method of POST and a Status of 303. This is the masked request that crawlers ignore.
   • Second Entry: Immediately following, a request to the new filtered URL with a Method of GET and a Status of 200. This is the final page your browser loads.

Seeing this POST -> 303 -> GET -> 200 sequence is definitive proof that the PRG Pattern Link Masking extension is working correctly.

⚠️ Warning: If you click a filter and only see a single GET request with a 200 status, the PRG pattern is not active for that link. Ensure the module is enabled in the configuration and that you have cleared all Magento caches.
