Lazy loading helps defer images that are not immediately needed, but a poor implementation can hide images from search crawlers or delay the first visible hero. Test both the visitor journey and the rendered HTML. The question is which images can wait, not whether every image should receive the same attribute.
Decision framework
| Step | Practical check |
|---|---|
| Classify images | Separate above-the-fold hero and product images from lower-page supporting images. |
| Check markup | Confirm important image URLs appear in rendered HTML and load without a click. |
| Test scroll and resize | Watch whether deferred images load when they enter the viewport. |
| Inspect search view | Use URL Inspection or an equivalent rendered view to confirm discoverability. |
How to make the decision
Make a page-level image inventory: URL, visible position, loading behavior, source attribute, dimensions and alt purpose. Keep the first meaningful image eager when it is critical to the page experience. For deferred content, use supported browser or intersection behavior rather than a custom click requirement. Recheck with JavaScript enabled, a slower connection and a crawler-rendered view. Preserve aspect ratio so loading does not shift text.
Worked example
Synthetic category page: product images below the first row load as the visitor scrolls, but the first product image is also deferred and remains blank until a script runs. The team removes lazy loading from that visible image, confirms lower rows still defer, and checks that URLs appear in the rendered page. The decision is scoped to the category template.
What can change the answer
Google Search does not interact with a page as a shopper does; content that requires a click or swipe to load can be missed. A no-JavaScript test is useful context but not the only search rendering check.
Review checklist
- Are immediately visible images prioritized?
- Do below-page images load when visible without a click?
- Can a rendered crawler view find the image URLs?
Common question
Should every product image be eager loaded?
No. Prioritize images likely to be visible at opening; defer later images and verify their loading behavior.
