About

The rel="dns-prefetch" attribute on HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.

It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.

The rel="prerender" attribute on HTML <link> elements is a deprecated browser hint that instructed web browsers to preload and render a web page in the background before navigation occurred.

It was used to improve perceived performance by preparing and rendering likely next pages before users opened them.
