FAQ
Q1: Will lazy loading affect my Magento 2 SEO and Google image indexing? A1: Googlebot supports lazy loading and can render pages that use both the native loading="lazy" attribute and JavaScript-based Intersection Observer fallbacks. Google has officially confirmed that lazy-loaded images are discoverable and indexable. However, you should exclude your most important product images — the ones you want indexed as quickly as possible — using the data-skip-lazy="1" attribute. This ensures that Google's crawler finds and indexes your primary product imagery without waiting for scroll simulation, while still benefiting from the performance improvement on lower-priority images throughout the page.
Q2: Does MageRa Lazy Load work with Magento 2 page builder and CMS blocks? A2: Yes. The extension's CMS Images toggle enables lazy loading for all images rendered within CMS pages and CMS blocks, including content created with Magento Page Builder. The extension processes image tags in the HTML output regardless of how they were authored — whether inline HTML, Page Builder components, or widget outputs. If you have specific CMS images that must load immediately (such as hero banners in a promotional landing page), you can exclude them individually using the data-skip-lazy="1" attribute without disabling lazy loading for the entire CMS content scope.
Q3: What happens if a customer has JavaScript disabled in their browser? A3: On browsers that support the native loading="lazy" attribute (Chrome 77+, Firefox 75+, Edge 79+), lazy loading works without any JavaScript at all — it is a browser-level feature. On browsers that require the JavaScript fallback (Safari, older versions of Chrome and Firefox), disabling JavaScript would prevent deferred images from loading. In practice, less than one percent of eCommerce traffic has JavaScript disabled, and those sessions typically cannot complete a purchase anyway since Magento 2's checkout flow requires JavaScript. If you need to support JavaScript-free browsing, you can disable the extension for specific store views via the Magento 2 configuration scope selector.
