How to validate Fasterize optimizations on your website?
Introduction
Before putting your Fasterize-optimized site into production, it is essential to validate that everything is working correctly: visual rendering, performance, cache, and compliance with personal data regulations.
This guide provides step-by-step instructions for testing and validating Fasterize optimizations on your website to ensure smooth and compliant integration.
💡 This process complements your internal testing by focusing on the specific features of Fasterize.
Step 1: Install and use the Fasterize extension
Installation
To facilitate your testing, install the dedicated extension:
⚠️ Only use the extension on your website domain.
already connected to Fasterize in Discovery mode
Usage
Once installed, open the extension's Info tab. You will see a color indicator that informs you about the optimization status of the page:
- 🟢 Green → the page is optimized and served from the Fasterize cache
- 🟠 Orange → the page is excluded from the cache or not optimized
You can also compare two versions of the same page:
- See optimized pages: displays the accelerated version
- See unoptimized pages: displays the original version
💡 The Fasterize extension is your revenue dashboard: with one click, you can view the status and performance of a page.
Step 2: Check visual and functional optimizations
Check the images
- Confirm that all images are displayed correctly.
- Compare the visual quality before and after optimization to ensure that it meets your standards.
Check the site's features
Test all key interactions:
- Sliders and carousels
- Forms and back-office data reporting
- Menus, buttons, and navigation
- Log in / Log out
- Complete purchasing journey
- Filters and search
⚠️ If there is a difference in behavior between the original version and the optimized version, note it in the tracking file provided by your CSE.
Step 3: Check the Fasterize cache
Understanding how the cache works
Fasterize uses several types of cache, depending on the nature of your pages:
- Hidden pages: standard pages stored in the cache. In Discovery mode, reload each page 2 to 3 times to simulate real behavior. The extension turns green when the page is properly cached.
- Smartcache (User Cache) : dynamic areas (such as a basket or a custom block) identified by CSS selectors and excluded from the cache.
- In the Smartcache tab → Highlight dynamic areas, these areas appear with an orange border.
- Excluded pages: sensitive pages (shopping cart, checkout process, customer area) that are not optimized. The extension is displayed in orange.
Standard validation scenario
- Create a complete user session: log in, add products to the cart, add favorites, etc.
- Browse through several pages and reload them 2 to 3 times to cache them.
- Open an incognito window (or another browser), activate the extension, and repeat the same steps.
- Check the privacy settings: no data from your logged-in session should appear.
💡 This scenario ensures that the Fasterize cache respects data privacy while improving performance.
Step 4: Report anomalies and follow up on corrections
Your CSE (Customer Success Engineer) will share a recipe tracking file with you.
Use it for:
- Report each anomaly (with the URL and a screenshot if possible)
- Monitor their treatment and correction
- Validate fixes with your CSE
💡 The more precise your feedback is, the faster and more reliable the resolution will be.
Conclusion
By following these steps, you can verify that Fasterize has been properly integrated into your website before going live.
You hereby guarantee that:
- accurate visual rendering,
- smooth operation,
- an optimal cache configuration,
- and effective collaboration with your works council.
✅ You are now ready to finalize your site recipe and take full advantage of Fasterize optimizations.
