Image use, alternative text and visible size
Check gallery images and foreign embeds separately. The platform output and an embedded third-party element can use different loading strategies.
Check the specific image in the respective element or app content. An image can perform different tasks as an informative graphic, linked card or pure decoration.
Where to check the setting in Wix
Select the specific image used or the app image and control its alternative text. After publishing, check the mobile image output. A background image has a different task than a linked product image and requires its own classification.
Example of this specific finding
Illustrative control case: Twenty images far below the first visible area load immediately. The large visible hero image, on the other hand, does not belong in the same delay rule.
follow-up audit in Wix
On the published mobile page, control the loaded image, its alternative and the reserved area. A change in the editor must then be published.
Suitable downstream images are loaded delayed and checked in the network protocol when scrolling. Continue to request visible key images in time.
Derogations and scope
Lack of lazy loading on the LCP image is often intentional. A blanket rule for all images can worsen the visible loading time.
Reference: published Wix/Wix Studio websites. SEO settings differ by static page, dynamic page type and installed app; do not require a freely managed server configuration.
