8 in score with pro plan CDN enabled, what are we missing? #score

Hello Cloudflare team,

We are using Cloudflare under the Pro Plan for our website sibarirepublic.com, aiming to improve performance and speed. However, we are still seeing very low scores on performance tools such as:

Google PageSpeed Insights (Mobile): 22

Cloudflare Observatory: 8

Here’s what we’ve done so far:

Enabled all recommended optimizations via the Cloudflare dashboard (image optimization, HTTP/2, Brotli compression, Rocket Loader, etc.).

Integrated with WordPress using the W3 Total Cache plugin.

Enabled deferred image loading and JavaScript/CSS minification.

CDN seems to be working, but we’re still getting flags for unoptimized images and render-blocking JavaScript.

We also noticed the image transformation feature shows “0 of 5000 images transformed”, even though it’s enabled.

Questions:
Are there any additional settings or requirements to ensure that Cloudflare is serving fully optimized images?

Is it better to use the official Cloudflare WordPress plugin instead of W3 Total Cache, even though the plugin hasn’t been updated in over a year?

Could you help verify if our current configuration is properly leveraging Cloudflare’s performance tools?

Any guidance you can provide to help us improve performance scores (especially on mobile) would be greatly appreciated.

Thanks in advance for your support.

Best regards,

I'm happy to help you with your performance concerns.

To address your questions:

Optimized Images: According to the documentation, Cloudflare's image optimization features may not help much if you are already optimizing your images in some way (Smush.it, etc.) [1]. It's possible that your existing image optimization setup is interfering with Cloudflare's image optimization. You can try disabling other image optimization services and see if Cloudflare's image optimization works as expected.
Cloudflare WordPress Plugin vs W3 Total Cache: The official Cloudflare WordPress plugin allows you to push necessary assets to your users using HTTP/2 Server Push, which can dramatically reduce the amount of roundtrips required to load CSS and JavaScript [2]. However, since the plugin hasn't been updated in over a year, it's essential to weigh the benefits against potential compatibility issues. You may want to consider using the plugin, but keep a close eye on its performance and compatibility with your WordPress setup.
Verifying Configuration: To ensure you're properly leveraging Cloudflare's performance tools, I recommend reviewing the documentation on caching anonymous page views [2], optimizing images [2], and enabling HTTP/2 [2]. Double-check that you've enabled all recommended optimizations via the Cloudflare dashboard and that your WordPress setup is correctly configured to work with Cloudflare.
Improving Performance Scores: To improve performance scores, especially on mobile, consider the following:
- Enable Mirage to optimize images for mobile visitors [2].
- Use Polish to compress images and strip metadata [2].
- Ensure that your website is loaded over HTTPS to enable HTTP/2 [2].
- Review the documentation on caching static HTML with WordPress/WooCommerce [2] to optimize your caching setup.

Please let me know if you have any further questions or concerns.

We have that options enabled and the score remains low

We also noticed the image transformation feature shows “0 of 5000 images transformed”, even though it’s enabled.

the toggle allows you to use the product, but won't do anything unless you're actually serving transformation requests:

Transform via URL

You can convert and resize images by requesting them via a specially-formatted URL. This way you do not need to write any code, only change HTML markup of your website to use the new URLs. The format is:
