slow page speed after importing reviews

[George-nelli11]

Super frustrated at this point. Every time I add reviews to the product page, my load time spikes. Is there any quick fix or should I just change to other review app?

Hello there George @George-nelli11  If you’ve already done the basic troubleshooting procedures such as clearing the cookies in your browser and trying to load on an incognito browser, then I suggest just using another product reviews app. 
Which one are you currently using? If it isn’t the judge.me product reviews app, I highly suggest switching to it.

Hello @George-nelli11

If your reviews widget is pulling in a ton of JS every time, that’ll definitely slow things down. Before you rip everything out, try these quick fixes:

1. Lazy-load the reviews
Wrap your reviews section in a placeholder and only fetch/render them when the user scrolls down. That way the page’s main content loads first, and the reviews load in later via a small script.

2. Use a static import
With Kudosi Reviews you can import all the review data into Shopify’s metafields and then render them directly in your Liquid templates. No extra external scripts means near-instant load times.

3. Defer or async your widget script
If you’re stuck with a client-side widget, add defer or async to its <script> tag so it doesn’t block the initial render.

If you’d rather swap apps, look for one advertised as “server-side rendering” or “minimal footprint”—but honestly, switching to Kudosi’s static-import approach is usually enough to keep your load times snappy while still showing off those reviews.

It might be due to the review app loading too many scripts or large assets. You can check the review app's built-in settings and see if there's an option to lazy-load the reviews (so they only get loaded after the rest of a product page), or limit the number of reviews shown initially (for example, show 5 and a 'Load more' button'). Otherwise, try a light review app like Judge.me or Loox if you don't mind testing them out. 🙂

Hi @George-nelli11

From what you said here, the app you used to add reviews may not be compatible with the theme used on the store. If you manage to resolve this issue, it is better to contact the related review app support team and get help from them directly. If they fail to resolve this situation, it is better to contact the theme developers for further help and analyze this issue together. A kind reminder here, thank you!
