9Don't prefetch everything visible in the viewport. Prefetch based on user intent to avoid wasted bandwidth.

11**Incorrect (prefetch all visible links):**
12 
13```tsx
14<Link href="/page" prefetch={true}>Page</Link>

17**Correct (intent-based prefetching):**
18 
19```tsx
20<Link href="/page" prefetch={false}>Page</Link>
