3. 📖 Advanced Recommendations & FAQ

While the JaJuMa PRG Pattern Link Masking extension is a powerful "set and forget" tool, its deployment strategy can be optimized based on your store's history.
Implementing the extension on a brand-new site versus a long-established one requires different supporting actions to maximize and accelerate the SEO benefits.
This guide provides strategic, experience-based advice for both scenarios.

3.1 🚀 Recommendations for Existing/Live Stores

If your Magento store has been live for some time, it's highly likely that search engines have already crawled and indexed thousands of your faceted navigation URLs.
This creates a "historical SEO debt."
Simply enabling the extension will prevent this problem from getting worse, but it won't retroactively remove the old, low-value URLs from Google's index.

To accelerate the cleanup process and reclaim your crawl budget faster, we recommend a three-step approach:

1. Enable the Extension:
   First and foremost, enable the module by setting Module Enable to Yes.
   This immediately stops the creation of new crawlable filter URLs.

2. Update robots.txt:
   Next, you must explicitly tell search engines to stop visiting the legacy filter URL patterns.
   Add Disallow rules to your robots.txt file for every filter parameter.
   This is the most direct way to conserve your crawl budget.

   Example `robots.txt` entries:
   User-agent: *
   Disallow: /*?color=
   Disallow: /*?size=
   Disallow: /*?price=
   Disallow: /*?dir=
   Disallow: /*?limit=

3. Maintain SEO Fundamentals:
   As a best practice and a fallback measure, ensure your category pages have correct self-referencing rel="canonical" tags and appropriate meta robots settings configured within Magento.
   The PRG pattern is your primary defense, but a strong foundation is always recommended.

💡 Pro Tip: The robots.txt update is the critical step for existing stores. It proactively tells Google, "Don't waste time on these paths anymore," which speeds up the process of Google focusing its crawl budget on your important pages. Without this step, it could take months for Google to naturally de-prioritize the old URLs.

3.2 🌱 Recommendations for New Stores

For new stores that have not yet been heavily indexed by search engines, the strategy is simpler as there is no historical SEO debt to clean up.

1. Enable the Extension from Day One: Activate the PRG Pattern Link Masking module before your site goes live or as soon as it is installed. This prevents layered navigation SEO issues from ever occurring.
2. Focus on SEO Fundamentals: You do not need to add aggressive Disallow rules to your robots.txt file for this purpose. Instead, focus on ensuring your core Magento SEO settings are correct, particularly the use of rel="canonical" tags for product and category pages to prevent any other potential duplicate content issues.

By starting with the PRG pattern active, you ensure a clean, efficient crawl path for search engines right from the beginning.

3.3 ❓ Frequently Asked Questions (FAQ)

Here are answers to common questions about the functionality and compatibility of the PRG Pattern Link Masking extension.

Q: Will this extension break existing bookmarks or shared links to filtered pages?

A: No. A key benefit of the PRG pattern is that the final GET request URL remains unchanged. Any existing backlinks, bookmarks, or links shared on social media will continue to work exactly as they did before. The optimization process is completely invisible to the end-user and preserves all existing URLs.

Q: Is this extension compatible with Hyvä Themes and Mage-OS?

A: Yes, the extension is fully compatible with both Hyvä Themes and Mage-OS. JaJuMa provides a dedicated compatibility module to ensure seamless integration and performance with these modern frontends.

Q: What about third-party layered navigation extensions, such as those from Amasty or WeltPixel?

A: This extension is developed and tested for the default Magento 2 Luma and Hyvä layered navigation systems.
While it is architected following Magento best practices, direct compatibility with heavily modified third-party navigation modules is not guaranteed out-of-the-box.
Customization may be required for such integrations.

Q: Is the PRG Pattern method better than just using a noindex tag on filter pages?

A: Yes, it is a significantly superior strategy.
A noindex tag only tells search engines not to show a page in search results; it does not prevent them from crawling the page in the first place. This means your crawl budget is still wasted.
The PRG Pattern solves the problem at its root by preventing the crawl itself, making it a far more efficient and effective solution for both indexing and crawl budget optimization.
