1. What is lazy load?
By default, the review widget is prepared as soon as your page opens, even if the widget sits far down the page and the visitor never scrolls that far.
Lazy Load changes this. When it is turned on, WiserReview waits and only prepares the review widget when the visitor scrolls near it.
Benefits:
- Less work for the browser while your page is opening
- Faster first impression for your visitors
- Better Google PageSpeed and Core Web Vitals scores on pages where the review widget sits below the fold
Your widget still looks and behaves exactly the same once it appears.
2. Visitors will not see an empty space
Lazy Load does not wait until the widget is fully on screen.
It starts preparing the widget slightly before it reaches the visible area of the screen.
In practice, the reviews are already on screen by the time the visitor scrolls down to them, so there is no blank gap and no sudden pop-in.
3. What is supported
Available for:
- The Product Review widget (the main review section)
- Stores that add the widget using the Custom install option
Not available yet (these always load together with the page):
- Video Reviews carousel and other carousel widgets
- Floating review badge
- Review Wall
- Star rating badge, Q&A, UGC, popup, avatar and all other widget types
- Stores using a platform app or plugin – such as Shopify, WooCommerce, PrestaShop, OpenCart, Wix, Squarespace, BigCommerce and Ecwid – because on those platforms the widget is placed automatically for you
Suggested wording for support replies:
“Lazy Load is currently available for the Product Review widget when it is added using the Custom install option. We are working on extending it to other widget types and platform integrations.”
4. How to turn it on
1. Log in to your WiserReview dashboard.
2. Go to Widgets and open the Product Review widget you want to change.
3. Click Install to open the install panel.
4. Select the Custom tab.
5. In step 2 of the panel, tick the “Enable Lazy Load” checkbox.
The dashboard describes it as: “Widget loads only when the visitor scrolls near it. This improves page speed.”
6. The widget code shown below the checkbox updates straight away. Click it to copy.
7. Replace the old widget code on your website with the copied one.
8. Save or publish your page, then reload your storefront.
That is the whole setup. There is nothing else to configure.
5. How to check it is working
1. Open one of your product pages in a fresh browser tab.
2. Do not scroll. The review section should not be built yet.
3. Scroll down toward the review section – the reviews appear as you approach them.
If the widget still loads immediately:
- Make sure you replaced the old widget code with the new copied code, and that the page was saved or published.
- Make sure you copied the code from the Product Review widget (Lazy Load applies to that widget only).
- Clear your website cache and any CDN cache, then try again in a private browsing window.
6. Other performance points you can share
- The WiserReview script is loaded in a way that never blocks your page from appearing.
- A page only loads what it needs for the widgets actually placed on that page.
