LCP request discovery

Connor Clark

Optimize LCP by making the LCP image discoverable from the HTML immediately, prioritizing it, and avoiding lazy-loading.

How to pass this insight

If a page's LCP is an image:

Use fetchpriority=high on the image element, or on its preload directive.
Ensure the image is discoverable from the main document (either because it is directly in the HTML, or the image is preloaded).
Avoid loading=lazy for the image.

Important: When preloading the image, ensure fetchpriority=high is set on the preload as well as the image.
