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.

SearchAction is a structured data type from Schema.org that describes a website's search capability.

Before November 2024, it was used by Google to enable the "Sitelinks Search Box" feature, which displayed a search bar for a website directly within the search results snippet. However, since Google deprecated this feature, there is no evidence that other search engines or apps currently support it.
