resource-prioritization-strategy

To improve LCP, you apply fetchpriority and preload hints to critical assets like images and fonts, signaling their importance to the browser so they load faster and accelerate the page's Largest Contentful Paint.

Assets discovered late cause web performance issues because the browser delays fetching them until parsing reaches the markup. Applying preload or fetchpriority to these resources reduces input latency and visual delays by forcing early discovery.

The best way to prioritize critical images and fonts for Core Web Vitals is to apply targeted fetchpriority attributes and preload tags in your HTML markup, ensuring the browser fetches high-impact resources before others.

Yes, you can use resource prioritization hints to reduce input latency and visual delays. Applying preload and fetchpriority to late-discovered critical resources ensures they load earlier, improving FID, TBT, and CLS metrics.

You should not use preload or prefetch hints for non-critical assets loading or resources already easily discoverable in the initial HTML, as misusing these prioritization signals can waste bandwidth and delay more important page resources.
